HP Multi Jet Fusion technology oers speed advantages and control over part and material properties beyond
those found in other 3D printing processes.
HP Multi Jet Fusion technology starts by laying down a thin layer of material in the working area. Next, the
carriage containing an HP Thermal Inkjet array passes from left to right, printing chemical agents across the full
working area. The layering and energy processes are combined in a continuous pass of the second carriage from
top to bottom. The process continues, layer-by-layer, until a complete part is formed. At each layer, the carriages
change direction for optimum productivity.
English
a. The material is recoated across the work area.
b. A fusing agent (F) is selectively applied where the particles are to fuse together.
c. A detailing agent (D) is selectively applied where the fusing action needs to be reduced or amplied. In this
example, the detailing agent reduces fusing at the boundary to produce a part with sharp and smooth
edges.
d. The work area is exposed to fusing energy.
e. The part now consists of fused and unfused areas.
The process is repeated until the complete part has been formed.
NOTE: The sequence of steps above is typical, but may be changed in specic hardware implementations.
HP Multi Jet Fusion technology can realize the full potential of 3D printing through the production of highly
functional parts. Using HP Thermal Inkjet arrays, HP Multi Jet Fusion technology is built on HP’s technical core

competency of rapidly and accurately placing precise (and minute) quantities of multiple types of uids. This
gives HP Multi Jet Fusion technology a versatility and potential not found in other 3D printing technologies.
In addition to fusing and detailing agents, HP Multi Jet Fusion technology can employ additional agents to
transform properties at each volumetric pixel (or voxel). These agents, transforming agents, deposited point-bypoint across each cross-section, allow HP Multi Jet Fusion technology to produce parts that cannot be made by
other methods.
For example, taking advantage of HP’s in-depth knowledge of color science, HP Multi Jet Fusion printers could
selectively print a dierent color at each voxel with agents containing cyan, magenta, yellow, or black (CMYK)
colorants.
The long-term vision for HP Multi Jet Fusion technology is to create parts with controllably variable—even quite
dierent—mechanical and physical properties within a single part or among separate parts processed
simultaneously in the working area. This is accomplished by controlling the interaction of the fusing and detailing
agents with each other, with the material to be fused, and with additional transforming agents.
HP Multi Jet Fusion technology can provide design and manufacturing possibilities that surpass the limits of our
imagination. That’s what technological breakthroughs do.
Usage recommendations
1. Prepare your design for printing: Open your 3D model and check for errors with easy-to-use HP software.
2. Pack models and send to printer: Place multiple models into the software and submit the job to the printer.
3. Add materials: Insert the material cartridges into the processing station.
4. Automated mixing: You will have a clean loading and mixing experience because the processing station is
enclosed and automated. Materials are loaded into the build unit.
5. Remove the build unit from the processing station.
6. Slide the build unit into the printer.
7. Printing with voxel-level control: Just tap Start to get extreme dimensional accuracy and ne detail, thanks
to HP’s unique multi-agent printing process.

5 Printer and processing station networking
The printer provides a single RJ-45 port for a network connection. In order to meet Class B specications, the use
of shielded I/O cables is required. For optimal performance, you are recommended to use Cat 5/5e or Cat 6
cabling and gigabit-capable local network equipment.
A correct network setup is required to operate the printer, as all communication with printing and management
software happens through the network.
Conguration
To access the network settings, tap and then on the front panel.
Hostname
English
You can assign a customized hostname to the printer. If the network infrastructure supports it, the printer will
attempt to register the hostname to the DNS service, making it possible to address the printer using the
hostname rather than the IP address.
Similarly, you can assign the domain suix, to dene the printer’s fully qualied domain name.
IPv4 conguration
You can select whether the printer should try to discover automatically the IPv4 network settings using the DHCP
protocol, or whether you want to congure them manually. These settings include:
● IP address: The unique Internet Protocol address assigned to the printer.
● Subnet mask: The mask corresponding to the printer’s IP address.
● Default gateway: The IP address of the network gateway.
● DNS conguration method: Whether DNS servers should be assigned by DHCP service or manually.
● Primary and secondary DNS servers: The IP addresses of the DNS servers.
Link speed
The embedded network controller supports connection to IEEE 802.3 10Base-T Ethernet, IEEE 802.3u 100BaseTX Fast Ethernet, and 802.3ab 1000Base-T Gigabit Ethernet compliant networks. When connected and powered
on, the printer auto-negotiates with your network to operate with a link speed of 10, 100, or 1000 Mbps, and to
communicate using full- or half-duplex mode. However, you can manually congure the link using the printer's
front panel, or through other conguration tools once network communication is established.
ENWW Conguration 35
English
Troubleshooting
Link issues
The printer has status lights (LEDs) beside the network connector that indicate the link status and network
activity.
● When the green light is on, the printer has successfully linked to the network.
● When the yellow light is blinking, there is transmission activity over the network.
If the printer fails to connect to the network, both LEDs will be o. In this situation, try the following steps:
1. Check the cable connections at both ends.
2. Consider replacing the cables with ones that are known to work.
3. Consider switching to another network connector in the network switch, hub, or device to which the printer
is connected.
4. Manually congure the link setting to match the port conguration of the network hub or switch.
5. In case of doubt or misconguration of link settings, reset the network parameters to their factory settings.
Restore factory settings
In the case of accidental misconguration, you can reset the network settings to the factory defaults by tapping
Restore factory settings in the Network Settings conguration menu.

NOTE: If the new printhead is rejected or you are asked to reseat it, try cleaning the printhead contacts (see
Clean the printhead contacts on page 136).
Printhead cleaning roll
The printhead cleaning roll is a roll of absorbent material used in the normal operation of the printer to wipe the
printheads periodically: at the beginning and end of printing, while printing, on printhead check and clean, and so
on. This helps the printheads to deliver agents continuously and maintain print quality.
The roll should be replaced whenever it is used up, to avoid damaging the printheads. The frequency of
replacement depends on your use of the printer. A single roll will last for approximately 10 full build jobs or
50,000 layers in Balanced print mode.
An alert is displayed when 75% of the roll has been used, and again when 95% of it has been used. You can
choose to replace the roll at any time. The printer will not print when the roll has been 100% used.

● The HP Jet Fusion 4200 and 4210 accept cartridges with a capacity of 30 or 300 liters.
● The HP Jet Fusion 4210B accepts the use of the rellable HP Material Loading Tank allowing the use of bulk
material. It also accepts cartridges with a capacity of 30 and 300 liters.
The weight of the cartridge varies according to the material type. Special care must be taken to avoid personal
injury when handling heavy cartridges.
If pressure is put on a cartridge while it is being vacuumed, and the connection is removed, material spills may
happen. To avoid spills:
● Do not remove the handle while vacuuming.
● Never place anything heavy—more than 1 kg (2.2 lb)—on top of a cartridge.
● Take care not to drop a cartridge.
● Do not try to force the last of the material out of an almost-empty cartridge by pressing the bag inside the
cartridge.
Replace a cartridge
A cartridge should be removed and replaced when it is empty or past its expiry date. An empty cartridge is
indicated in the front panel and by the LED beside the cartridge.
CAUTION: Removing a cartridge before it is empty is not recommended. Cartridges are not designed for storing
material after removing the seal, and storing an opened cartridge containing material can render the material
unusable and cause safety hazards, such as a cloud of material if dropped. Depending on the material, it can be
sensitive to temperature, humidity, or other factors. Using cartridges under uncontrolled conditions can aect
the functionality of the equipment or severely damage it.

4. Use a lift trolley to move the full material loading tank next to the external tank.
NOTE: If the material loading tank has been stored for some time before use, HP recommends using a
drum rotator to rotate it in order to uncompact it. For this operation, the storage lid must be used (not the
loading lid) and properly closed with the clamp. The number of turns to uncompact the material depends
on the material and on the level of compaction; however, in general 90 seconds at 20 rpm should be
enough. If you take no material from the material loading tank for some time, you may need to use the
drum rotator again.
CAUTION: If you use a drum rotator, take care that it does not rub against the base or the cover of the
material loading tank while rotating.
5. Connect the material loading tank connector to the lid.
NOTE: HP recommends using tanks in the same order in which they were lled from the bulk material

The customer is responsible for tracking bulk material usage and material loading tank contents.
English
You should maintain logs that, at minimum, track the history of the bulk material received (part number, lot
number, expiration date, and so on). In addition, each material loading tank requires identication of the bulk
material details (part number, lot number, expiration, ll sequence) and any other relevant remarks (such as date
of lling). The material loading tank details should be placed in a visible area.
Fill the material loading tanks from the bulk material supply
The recommended method is to create your own infrastructure to transfer the material according to the
requirements of the material. Check the form in which the material supply arrives, and its requirements.
CAUTION: It is important to transfer only material into the processing station. Your own infrastructure must
protect against the suction of small parts into the processing station, which can cause safety risks and
malfunctions.
You can connect a material loading tank to the processing station: it is capable of transferring the material. At the
front panel, tap , then Fresh material > Ooad.
IMPORTANT: Ensure that the material type in the bulk supply is the same as the material currently loaded in the
processing station.
Ensure that the material loading tank does not contain any other material type.
If you want to change to a dierent type of material, rst clean the inside of the tank with an explosion-protected
vacuum cleaner (do not use cleaning products). Also clean the pipe thoroughly, removing all material.

8. At the end, make sure the part of the tube coming from the external equipment and the bulk supply is not
in contact with the material and tap Continue on the front panel. Processing will extract the material
remaining in the tube.
9. Disconnect the tube from the top of the processing station and put back the rubber, tap, and clamp.
10. Place the external tank.
It is the responsibility of the owner to maintain records of material batch information and usage.
● Identify each tank with product number, batch number, and warranty/expiration date. Do not use materials
after their expiration date has passed.
● In order to ensure the traceability of fresh material, be sure that the material loading tank is empty of
material from previous batches before the rell operation.
● If you also need to ensure the traceability of recycled material, you will need to empty all the build units and
processing stations that will work with the new material batch, using the Clean Workow and installing an
empty overow tank when starting. Otherwise the recycled material will have a random composition of
material coming from previous batches.
● Bulk supply must be stored and handled following the HP guidelines applicable to that specic material.
● Not following these traceability practices can invalidate claims against the warranty of the equipment or
consumables.
Material cartridge troubleshooting
1. Check that the cartridge is designed for your printer.
2. Use the correct procedure to change cartridges, through the front panel.
ENWW Processing station 61
3. Check that there is no obstruction in the cartridge connector.
English
4. Check that the cartridge is correctly oriented (compare with another cartridge).
5. Ensure that you have inserted the connector correctly and fully. You should hear a click.
6. If the problem still remains, call your support representative.
Maintain the cartridges
Before use, the material must acclimatize to the environmental conditions of the room for at least two days.
During the normal lifetime of a cartridge, no specic maintenance is required. However, to maintain the highest
quality, replace a cartridge when it reaches its expiration date. An alert noties you when any cartridge reaches
its expiration date.
Store the cartridges
Cartridges should be stored according to cartridge specications. Before use, a cartridge should be kept at
processing-station environmental conditions for at least 2 days.
CAUTION: HP recommends storing only sealed cartridges. Cartridges are not designed for storing material after
removing the seal, and storing an opened cartridge containing material can render the material unusable and
cause safety hazards, such as a cloud of material if dropped. Depending on the material, it can be sensitive to
temperature, humidity, or other factors. Using cartridges under uncontrolled conditions can aect the
functionality of the equipment or severely damage it.
Storage and build unit
CAUTION: HP recommends not to store material in the build unit for long time periods (>1-2 weeks approx.).
Storage and external tanks
When unpacking, all reused material is stored in the storage tank until it is full. After that, the reused material is
stored in the external tank. The mixer is fed with fresh material from the material cartridge and reused material
from the storage tank. If the storage tank is empty, you can ll it from the external tank by going to the front
panel and tapping , then Reused material > Fill. You will be asked to follow these steps:
1. Unlatch and open the lid.
62 Chapter 6 Supplies ENWW
2. Connect the external tank collector and pipe. You are recommended to wear gloves and goggles.
English
Replacement
3. The pipe sucks up material in its immediate vicinity. If you leave it in one position, it will consume all the
material in that area, while there is still material elsewhere in the tank. You should therefore move the pipe
around in the tank to access all the available material.
NOTE: You can insert the pipe with the vacuum switched o, if you like.
4. The process ends when the storage tank is full or the external tank is empty, whichever happens rst.
5. Unplug the external tank collector.
6. Close the lid and latches.
If you are loading material into the build unit, but there is not enough reused material in the storage tank to
process the job as specied, the front panel will ask you to ll it from the external tank. In this case, only the
reused material needed to load the build unit will be transferred.
If both tanks are full, or there is not enough space for unpacking, the processing station will ask you to replace
the external tank when the build unit is inserted.
CAUTION: Use HP-certied external tanks only. The use of third-party external tanks can cause safety risks,
material leakages, and malfunctions in the processing station; and may aect your system warranty.

Introduction
A print job can be created in either of the following ways:
● By using the HP SmartStream 3D Build Manager
NOTE: HP SmartStream 3D Build Manager supports STL and 3MF les.
● By using plugins added to Netfabb and Materialise Magics
The software creates slices that the printer can convert to layers in order to prepare the job. This preparation
process may take from 15 minutes to 2 hours depending on the complexity of the job. It can be done while
printing other jobs. Once ready, you can select the job to be printed from the job queue on the printer’s front
panel. If an error occurs while processing, a message appears on the front panel, and the printer cancels the job.
To retry, you have to resubmit the job.
The rest of this chapter may help you to avoid such errors.
File preparation
Tessellation
Before sending a job to a 3D printer, the model to be printed needs to be tessellated. That means that its
geometry needs to be converted into triangles, which are used by the printer to create layers. It is very important
to pay attention to this step: if not done correctly, it can cause problems such as inaccuracy or slow processing.
Standard formats in the additive manufacturing industry include 3MF (with more information about the model)
and STL.
A normal le size for a model is about 1–30 MB, but the size depends on the type of software that created it, the
number of triangles, the number and level of details, and so on.
When exporting to STL in a CAD package, you are often required to introduce some parameters such as angle
tolerance and deviation chord height. These parameters dene the resolution and le size of the part. The
following tips may help you to export with the best surface to le size ratio.
Solid Designer settings
Save as STL, click Options, and check the ASCII option. The recommended values for the Distance and Angle box
are 0.05 and 1.
66 Chapter 7 Design and printing guidelines ENWW

2. Select STL (*.stl) as the le type.
3. Click Options.
4. Choose the Binary option. Binary les are smaller than ASCII les for the same tessellation.
5. Choose Custom resolution.
6. Set the deviation tolerance to 0.05 mm.
7. Set the angle tolerance to 1°.

1. Click File > Save As.
2. Select STL (*.stl) as the le type.
3. Click File Name > Save.
4. Select Binary.
5. Select Detail Controls from the Mesh Options.
6. Set the maximum angle to 1, the maximum aspect ratio to 6, and the minimum edge length to 0.05.
STL problems
● Too many or too few triangles
ENWW File preparation 67
English
Too many triangles are diicult to process and, when a certain size is reached, the extra triangles do not
provide any further accuracy. For this reason, an excess of triangles could increase processing time for no
benet.
Triangulation of a surface causes faceting of the 3D model. The parameters used to output an STL model
aect how much faceting occurs.
Example of tessellation
● Holes in triangles
STL models commonly suer from surfaces that are not joined to their neighbors, and missing surfaces.

ENWW 71
English
Loading procedure
1. Ensure that the build unit is located on the processing station.
2. Ensure that the build unit printing platform is clean.
3. If you want to change the mix ratio, HP recommends cleaning the build unit rst. See Clean the build unit
on page 213.
NOTE: If you do not clean the build unit, it will contain some remaining material with the previous mix
ratio. In fact, some of the previous material may remain even after cleaning, so you may prefer to use a
dierent build unit. Check the material compatibility specications.
The default and recommended mix ratio for HP and Certied Polyamide 12 material is 20% fresh and 80%
reused; for HP and Certied Polyamide 11 it is 30% fresh and 70% reused. In some exceptional cases you
may want to change this ratio; for example, when using the processing station for the rst time you may
need to use 100% fresh material.
4. If you want to change to a dierent type of material, you should rst clean and purge the processing
station. See Purge the processing station on page 198. Then see Change to a dierent type of material
on page 75.
NOTE: If you do not intend to change the type of material, you may sometimes decide to clean the
processing station without purging it, perhaps because you think there is a problem with the particular
material that you have been using. See Clean the processing station on page 196.
CAUTION: A small amount of material may remain after cleaning. If your new material cannot tolerate any
contamination at all, you should use a dierent processing station.
5. Ensure that the material cartridges are loaded.
6. At the front panel, tap Build unit > Load.
7. Clean the sieve when requested by the front panel. See Clean the sieve on page 187.
8. Clean the loading nozzle sensor. See Clean the loading nozzle sensor on page 188.
9. Ensure the material loading inlet is properly clean.
10. Open the lid of the material loading inlet of the build unit.
72 Chapter 8 Load material into the build unit ENWW
11. Attach the material loading nozzle.
12. Dene the height by scrolling up and down the right bar. You can change the mix ratio if required.
English
The loading time depends on the mix ratio used and the quantity to load; here are some approximate
examples:
100% fresh material 80% recycled, 20% fresh
Full chamber 20 min 60–90 min
75% full 15 min 45–70 min
50% full 10 min 30–45 min
25% full 5 min 15–25 min
NOTE: The percentage full assumes a 20% packing density.
13. Tap Load to continue.
14. If the external laser tool is provided with your system and internal measurement seems to not work for any
reason, you can use the tool. To use it, attach the laser tool to the material loading inlet, use the lever to
turn on the laser tool and wait until the reading is done.
15. Tap Start.
NOTE: To ll the build unit completely with a mix ratio of 80% recycled, 20% fresh, you may need to do it
in two steps.
16. The supply container of the unit is lled. Wait for front panel to report that it has been successfully loaded.
ENWW Loading procedure 73

You cannot add a job while the current job is annealing.
NOTE: Adding a complex job during printing may slow down the processing of the current job, which could
cause printing problems.
Cancel a job
If you need to cancel the job while printing, tap Cancel and conrm it in the build status app on the printer's home
screen. The printer will cancel the job immediately.
IMPORTANT: Wait until the printer tells you it is safe to remove the build unit.
Proceed with the cooling process and unpacking if relevant. If no parts have been printed, the build unit should
be cleaned and loaded before using it again.

10 Unpack the build
As the build is at a high temperature while printing, you must wait about 30 minutes before extracting the build
unit from the printer. Then there is some further cooling time required in order to preserve part quality.
Tips
● Wear high-temperature-resistant gloves.
● Unpack calmly.
● There are physical buttons with which you can raise or lower the printing platform to make the unpacking
process more convenient.
● The sides and corners of the build chamber are colder than the center.
● If the parts are large, or the material around the parts seems very hot, leave them aside to cool down.
● If you notice that the vacuum speed slows down, try to unpack material from cooler locations or from
cooled parts.
1. When the printer tells you to proceed, open the door, extract the build unit, and place the safety lid over it.
2. Put on heat-resistant gloves and vacuum the top surface of the build unit with an external explosion-
protected vacuum cleaner.
3. At this point you can follow the natural cooling process; or, if your processing station is equipped with fast
cooling, you can choose fast cooling as an alternative.
Natural cooling
a. Move the build unit aside to cool down further.
CAUTION: You are recommended to lock the wheels of the build unit while it is outside the printer.
b. Wait. The cooling time depends on the size of the build; see Time scheduling on page 5.
86 Chapter 10 Unpack the build ENWW
c. Insert the build unit into the processing station.
English
Fast cooling
a. The build unit must be left to cool naturally for 3 or 4 hours before fast cooling can start. It does not
need to be inside the processing station during this time.
b. When you have inserted the build unit into the processing station, go to the processing station’s front
panel and tap Build unit > Fast cooling.
Fast cooling starts. You can tap at any time to cancel fast cooling. To resume the process, ensure
c.
that the build unit is inserted, and tap Fast cooling.
Default cooling times for PA12 material
Fast cooling Natural cooling (to reach 80°C)
Half-full build chamber (190 mm) 6.9 h 18.4 h
Full build chamber (380 mm) 9.4 h 33.4 h
Before starting the fast cooling process, you can modify the timing by tapping Modify.
TIP: Modify can be locked so that only administrators can modify the timing.
The timing is changed based on a cooling factor, which is related to speed; it is used to calculate the
fast cooling time for dierent job heights. Modifying this value may compromise part quality.
NOTE: The use of fast cooling may cause less uniformity in part cooling rates, and parts may nish
at higher temperatures than with natural cooling.
ENWW 87
English
d. Connect the reusable material collector to the safety lid, and tap Start on the front panel, which will
tell you the remaining time.
IMPORTANT: Ensure that the reusable material collector is in the high-suction position.
4. When cooling is complete, remove the safety lid and park it on the front of the build unit.
5. Use the build unit app on the processing station’s front panel to check that the build is ready for unpacking.
6. At the processing station’s front panel, tap Build unit > Unpack > Start to start the unpacking process.
IMPORTANT: The vacuum is activated when you tap Start, and the dust extractor is activated to keep the
process clean.
CAUTION: Wear heat-resistant gloves.
TIP: Close the hood to improve the performance of the dust extractor.
88 Chapter 10 Unpack the build ENWW
7. Redeploy the reusable material collector. You can use one of the following nozzles:
● Crevice nozzle, for cleaning the feed tray and narrow areas
● Unpacking nozzle, for normal unpacking
● Fine mesh nozzle, with a 2 mm mesh, for unpacking very small parts
● Wide nozzle, for cleaning the working area rapidly
CAUTION: Do not use the wide nozzle to clean the mesh shaker (on the feed trays of the build unit),
as you could damage the accessory and leave residues inside.
English
NOTE: You can regulate the suction power by rotating the tip of the material collector hose.
Low suction High suction
8. Vacuum the external perimeter of the platform (this step is unnecessary if you have used fast cooling).
ENWW 89
English
9. Raise the platform by pressing the button.
10. Vacuum the build to reveal the parts.
11. Clean each part separately to avoid having big clumps of material covering the part. You don’t need to clean
every surface thoroughly because:
● The material that is closest to the part or attached to it may reduce the overall quality of reused
material.
● That material will be removed anyway during sandblasting and postprocessing.
The example below shows a part that is ready for the bead blast.
Continue until all parts are extracted from the build chamber. Use the physical buttons to lift the platform
to reach all parts.
90 Chapter 10 Unpack the build ENWW
12. After checking that all parts are unpacked, put them in a box and take them to the postprocessing section.
13. Ensure that the printing platform is at its highest position.
14. Vacuum the empty printing platform and feed tray.
English
15. Tap Finish on the front panel.
16. Clean the surface of the build unit. See Clean the surface of the build unit on page 208.
17. Vacuum the platform control buttons to prevent loose material from blocking them.
ENWW 91
English
11 Part cleaning and postprocessing
Once parts have been unpacked from the build in the processing station, they should be cleaned. There are
dierent processes that can be followed, depending on your needs. In general, you will need equipment not
provided by HP. The main process recommended by HP is a combination of bead blasting (rst) and air blasting
(second).
● Bead blasting consists of applying compressed air mixed with an abrasive to the part in order to remove the
attached material. This is a generally appropriate solution; however, you may want to select dierent
abrasives or pressures for specic purposes.
● Air blasting consists of applying compressed air to the part in order to remove any material remaining after
bead blasting.
Depending on your specic needs, other postprocessing methods may be suitable for you.
The following options are available to improve surface nishing:
● Tumbling: The part is immersed in a vibro-tumbler full of abrasives, to smooth any surface roughness.
● Hand sanding: The surfaces of the part are smoothed by abrasion with sandpaper.
The following options are available for color-related nishing:
● Bead blasting with other additives consists of applying compressed air mixed with an abrasive and a
colored additive to the part in order to achieve homogeneous surface color.
● Dyeing consists of immersing the part in a controlled dyeing bath. All details and cavities of the part can be
reached.
● Painting the part with spray can, spray gun, or brush. For specic color nishing, HP recommends applying a
primer before painting the part. Repeat the process several times for optimal results.
Other industry-standard postprocessing methods may be used:
● Gluing, bonding, sealing
● Drilling, tapping
● Plating
● Coatings for wear resistance, conductivity, temperature resistance, strength, watertightness, resistance to
chemicals, gloss properties, UV protection, and so on
Contact your HP support representative to discuss solutions for your specic needs.
Consult your usual EHS specialist for advice on the appropriate measures for your location depending on the
post-processing method you use. Consult your local authorities to determine the correct manner in which to
dispose of wastes.
