MJF technology
HP Multi Jet Fusion technology oers control over part and material properties and speed advantages beyond
those found in other 3D printing technologies.
The HP MJF printing process begins by depositing a thin layer of material in the printer’s work area. Next, the
carriage containing an HP Thermal Inkjet array passes over the full work area, printing chemical fusing, detailing,
and coloring agents. During another pass of the carriage, the work area is exposed to fusing energy, which bonds
part layers together. The process continues, layer-by-layer, until a complete part is formed.
2 Chapter 1 Welcome to your MJF system ENWW
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.
By leveraging proven HP Thermal Inkjet technology and HP’s in-depth technical knowledge of rapidly and
accurately placing precise, minute quantities of multiple types of uids, MJF enables customers to produce highly
detailed parts and prototypes.
As agents are deposited point-by-point across each cross-section of each part, MJF technology can transform
part properties at each voxel, or volumetric pixel.
For example, when printing in color, MJF technology selectively prints color at the voxel level with cyan, magenta,
yellow, and black agents.
With MJF technology, HP will enable customers to realize the full potential of 3D printing.
Usage recommendations
1. Prepare design: Open your 3D model(s) and check for errors in the easy-to-use HP SmartStream 3D Build
Manager software.
2. Pack models and send to printer: Arrange your 3D models in the HP SmartStream 3D Build Manager and
submit the job to the printer.
ENWW Usage recommendations 3
3. Prepare printer: Clean your printer, check your long-term consumables, automatically check mechanical
systems.
4. Printing with voxel-level control: Just tap Start to start building parts with extreme dimensional accuracy
and ne detail, thanks to HP’s unique multi-agent printing process.
5. Automated material management: Unused material is automatically reclaimed and stored to be reused in
the next print job.
6. Retrieve and clean parts: The beacon and front panel indicate when parts are ready for retrieval. Retrieve
your parts from the build chamber and remove excess material with a bead and air blast system.

5 Printer networking
Introduction
The printer provides a single RJ-45 port for a network connection. For optimal performance, HP recommends
using 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 goes through the network.
IMPORTANT: In order to print, the printer must be connected to the Command Center, and the Command Center
must be connected to the cloud.
Connectivity requirement and remote monitoring
The customer will allow HP to install the HP Command Center software (or other applicable HP software that
controls the HP product and enables remote monitoring) on the customer’s computer.
The customer will keep that computer connected to the HP product, and the customer will keep the
HP Command Center software running on that computer and connected to the HP product at all times.
The customer will provide, at the customer’s sole expense, permanent HP Command Center software
connectivity to the HP secure cloud via permanent Internet connection through an HP-approved communications
channel and ensure such connectivity at all times as further specied in the site preparation guide. The customer
is responsible for restoring connectivity in a timely manner in the event of interruptions.
THE CUSTOMER AGREES THAT FAILURE TO MAINTAIN THE PRODUCT’S CONNECTION TO THE HP CLOUD AS
SPECIFIED IN THE SITE PREPARATION GUIDE WILL RESULT IN LIMITED OR NO PRODUCT FUNCTIONALITY AND
LIMITED SERVICE LEVEL.
HP products may collect the customer machine data. The customer grants HP and/or an HP authorized agent
permission to access remotely, via the HP Command Center software, the customer machine data from
HP products.
The customer machine data will be used by HP and/or an HP authorized agent for the purpose of providing
remote support, enabling enhanced diagnostics, preventive maintenance, software updating, calculating
supplies and consumables usage and statistics, and evaluating improvements to HP’s products and oerings in
the future. In addition, the customer machine data will help HP to determine how HP products are being used,
which product features are used the most, and to calculate various aggregate HP product usage statistics.
HP and/or HP authorized agents respect your privacy, are committed to protecting your machine data, and will
take reasonable precautions to prevent unauthorized access or disclosure and ensure the appropriate use of
your machine data. In the event that some data may be categorized as individual level data, HP and/or an
HP authorized agents will maintain the privacy of any such data, as well as all data collected, in accordance with
the HP Privacy Statement (http://www.hp.com/go/privacy) and the Personal Data Rights Notice
(http://welcome.hp.com/country/privacy/privacynotice) where applicable.

les, job names, job contents, part geometries, thermal maps, user names, or part names.
Conguration
To access the network settings, tap and then on the front panel.
Hostname
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.

26 Chapter 6 Design and printing guidelines ENWW
Introduction
3D printing oers a much higher level of freedom in terms of design than any other traditional manufacturing
technology. Designers and engineers can benet from this, and use new geometries and concepts that were not
feasible before. However, in order to optimize the design to be printed with MJF, you should be aware of some
characteristics of the printing process and its capabilities, as this could help to get the best of the technology.
The design and printing guidelines oer an overview of the steps to follow before sending a job to print, from le
preparation to the considerations that should be taken into account in the design of the parts and the orientation
of them in the build chamber to optimize the nal part quality and printing performance.
File preparation
File usage in the end-to-end workow
In the end-to-end workow of the printing process, the les pass through dierent software applications. For
example, the rst design may be done in a CAD program, while the job preparation will be handled in
HP SmartStream 3D Build Manager. If required, the printed part can be scanned in 3D and compared with the
original design.
Minimum specication for parts
When designing parts in your 3D modeling software, HP recommends keeping this minimum specication in
mind to avoid issues with parts and to achieve the best quality.
The minimum printable features in planes X, Y, and Z are as follows:
Minimum hole diameter at 1 mm thickness 0.5 mm (0.02 in)
Minimum shaft diameter at 10 mm height 1 mm (0.04 in)
Minimum printable font size for embossed or debossed letters or numbers 6 pt (2.1 mm) (0.083 in)
Minimum clearance at 1 mm thickness 0.5 mm (0.02 in)
Minimum slit between walls 0.5 mm (0.02 in)
ENWW Introduction 27
● Engraving. Multi Jet Fusion technology allows you to print letters and drawings with a very high resolution
and denition.
For the best possible output, any text, number, or drawing included in a part of the same color should have
at least 1 mm of depth or height. When using contrasting colors, there is no minimum.
The best orientation for embossing and debossing letters is to place them upside down in the build
chamber.
28 Chapter 6 Design and printing guidelines ENWW
● Solid part or structural ll. Multi Jet Fusion allows you to print topology-optimized, generative designs or
even small lattice structures. This kind of design helps to reduce the weight of the part and the quantity of
material used, which not only reduces the cost of the part but also helps to reduce the operating cost in
applications that are very weight-sensitive.
The minimum gap recommended in a lattice structure to ensure that all the material inside the part can be
removed is 5 mm.
● When printing a cantilever, the minimum wall thickness depends on the aspect ratio, which is the length
divided by the width.
Aspect ratio = Length/Width
For a cantilever with a width less than 1 mm, the aspect ratio should be less than 1. There are no specic
recommendations for widths greater than 1 mm.
ENWW File preparation 29
● In general, the minimum recommended wall thickness is 0.5 mm for short walls oriented in the XY plane,
and 1 mm for short walls oriented in the Z plane.
For parts with a high aspect ratio (>10:1), HP recommends increasing the wall thickness, or adding ribs or
llets to reinforce the part.
Very thick walls can accumulate heat and cause spot shrinkage in dense areas with an accumulation of
material.
For best results, ribs should be no thicker than their base wall.
TIP: Hollow out the part as much as possible, saving agent and material, and reducing sink marks.
● Minimum gap between parts to be assembled after printing. Sometimes a pair of printed parts need to t
together for the nal application. In these cases, HP recommends gaps of at least 0.5 mm between the
interface areas that should t together, in order to ensure correct assembly.
30 Chapter 6 Design and printing guidelines ENWW
● Minimum spacing and clearance between parts printed as assemblies. Assembly parts that are printed
together should have a minimum clearance of 0.7 mm. Parts with thick walls should have a larger gap to
ensure suicient material escape paths.
● Hollow closed geometries. Multi Jet Fusion is a process in which the parts are built by selectively fusing the
desired areas of a material-based layer. If the parts printed are hollow, drain holes need to be added to the
design to remove the material. The minimum recommended diameter of the holes is 5 mm; preferably
larger, for ease of cleaning. HP recommends including at least two holes.
● Glue lines. Parts larger than the maximum build size can be printed with Multi Jet Fusion by splitting them
into dierent parts. They can then be joined together by glueing, welding, or by pin inserts.
If you plan to glue parts together, HP recommends including interlocking features such as those shown in
the pictures below: as a guide to position the parts, to help them to bond together, and to facilitate the
glueing process. Remember to leave an additional space of 0.2 mm between parts for the glue, in addition
to the minimum spacing between parts printed as assemblies (see above).
ENWW File preparation 31
● Ducts. To remove material from narrow ducts, consider designing and printing a strip or a chain through the
duct. When the parts have been printed, you can pull out the chain to dislodge most of the material. Any
remaining material can be removed by the normal cleaning process.
Coloring parts
After creating your 3D model, it is recommended to color your model before bringing it into the HP SmartStream
3D Build Manager since coloring options are limited there. There are two primary ways of adding color to 3D
models:
● Color addition by part, face, or shell: Commonly seen in CAD programs, this allows you to color specic
areas of a part.
A model with the entire part colored
A model with the dierent colors on dierent faces
32 Chapter 6 Design and printing guidelines ENWW
● Texture mapping: Commonly seen in graphic art programs, texture mapping takes an image and wraps it
around a 3D object.
A model with a texture map
See your CAD or graphic arts software guidelines for how to use these features. You can also color previously
uncolored models in a free program, such as Microsoft 3D Builder, which is free on all Windows systems. 3D
Builder has easy-to-use color and texture map additions for beginners.
Saving and exporting les
After your les are designed and colored, your model needs to be tessellated, or converted into triangles, which
are used by the printer to create layers. Tessellation occurs when you save or export your model le into specic
le formats. The HP SmartStream 3D Build Manager accepts four dierent le formats:
● 3MF
NOTE: 3MF is the preferred le format for HP SmartStream 3D Build Manager.
However, defer to the recommended le export format chart below for color models.
● VRML 2 (.wrl)
● OBJ
● STL
NOTE: STL les do not carry color information. Use 3MF, VRML 2, or OBJ le formats for color models.
When saving or exporting your le, note that a normal le size for a model is about 1–200 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. HP does not recommend working with les of more than 4 GB—beyond that size, the extra resolution in the
le may have no eect on the printed part.
When exporting to STL, OBJ, or VRML 2 from 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 recommended parameters when exporting parts are an angle tolerance in the range 1–5
and a deviation chord height in the range 0.05–0.2. The angle tolerance should be reduced for parts with
cylindrical or spherical shapes, and the chord height should be minimized for parts with ne details and small
features.
Below, you will nd some recommended export parameters/settings for common 3D modeling programs.

34 Chapter 6 Design and printing guidelines ENWW
Creo Elements recommended export settings
Recommended export format: VRML (.wrl)
Recommended le export formats for color models
In addition to having the correct export settings, HP recommends saving your color models in specic le
formats, depending on which 3D modeling software program you use. Note that not all programs can export
texture maps, even though texture mapping features may be available in the software. If this is the case, it is
recommended to bring your uncolored model into a software that can export texture maps, and then add the
texture map in that software. There are free software options, such as Microsoft 3D Builder and Blender, that
allow you to do this.
Software Recommended le export format Can export texture?
3D Builder (16.1.651.0) 3MF Yes
Adobe Photoshop (19.1.4) VRML or OBJ Yes
Autodesk 3ds Max (2019) VRML Yes

NOTE: If you are saving your color models in the recommended format and are still experiencing issues
correctly opening your color models in HP SmartStream 3D Build Manager, see the printing tips and tricks
document.
ENWW File preparation 35
Tesselation problems
These are some common problems that you could experience during tessellation/exporting your les:
● Too many or too few triangles
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.
Repairing les
File-repairing software
● Magics – Materialise
● Autodesk Netfabb
● HP SmartStream 3D Build Manager
Common errors
Some common errors that cause part-quality-related issues are illustrated below. They can be xed in the native
CAD software; or, if that is not available, in Magics, Netfabb, or HP Smartstream 3D Build Manager. If these les
are not xed before attempting to build the design, either the software will not allow you to proceed due to poor
le quality, or your part will not have good quality. Therefore, it is prudent to spend time at this stage to check
that the CAD le designer produced a high-quality and printable design.
● Triangles not joined
36 Chapter 6 Design and printing guidelines ENWW
● Overlapping triangles
● Holes in parts
● Flipped-direction triangles
● Tiny shells
ENWW File preparation 37
HP SmartStream 3D Build Manager
The HP SmartStream 3D Build Manager must be used to send jobs to print. Therefore, after les are exported,
either from your CAD, graphic arts, or separate 3D build manager software, they must be brought into
SmartStream 3D Build Manager.
NOTE: For optimal dimensional accuracy, export parts separately instead of grouping them within one le.
In HP SmartStream 3D Build Manager, you will be able to access some color editing features, including:
● The ability to color an entire part with one color of your choosing
● The ability to edit the hue, lightness, and saturation of existing colors
● The ability to display a print preview of the color part to be printed
● The ability to print a color set model to test colors
See the HP SmartStream 3D Build Manager User Guide (http://www.hp.com/go/SmartStream3DBuildManager/
manuals) for full descriptions of these features, or view this video: https://www.youtube.com/watch?
v=3IfrpLMrJ4U&t=14s.
The software 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.

Material
The printer uses a mixture of fresh and reusable material—the conguration for PA12 material is 20% fresh,
80% reusable. The reusable material slot serves two functions:
● Adding reusable material. You may be prompted to put more reusable material into the machine if there is
● Removing excess reusable material. You may be prompted to remove reusable material if there is not
Material states
● Fresh: New, unused material.
● Reusable: Material that the printer has reclaimed from previous jobs, which may be reused for future jobs.
● Waste material: Used material that will not be reused.
● Mix ratio: A mixture of fresh and reclaimed material.
● Empty: Empty cartridges should be stored and used to reclaim material.
Mix ratio

through installing a reusable material supply.
enough space to hold all reusable material that the job will generate; the front panel will walk you through
installing an empty or partial supply to accommodate the excess material.
The default mix ratio is 20% fresh and 80% reusable material. However, when submitting a job through HP
SmartStream 3D Build Manager, you can select your preferred mix ratio.
When a job is selected to print, the correct levels of both fresh and reusable material can be added through
guided workows on the front panel before the start of printing.
Some jobs can be printed successfully only by adjusting the mix ratio based on the printer capacity.
If the submitted job exceeds the capacity of the printer, return to the build submission software to reduce the
height of the build or the packing density.
Material cartridges
The material cartridges dispense the material in the printer. Each material cartridge has a capacity of 10 liters.
The printer will not accept cartridges that have been modied or tampered with. See the material list for ordering
information.
There are two material cartridge slots, one for fresh material (on the left) and the other for reusable material (on
the right).
Any time you remove an empty cartridge from the fresh slot, be sure to peel o the fresh material label to reveal
the reusable material label underneath. This cartridge can now be lled with reusable material and used in the
reusable material slot.
Both fresh and reusable cartridges must be installed in order to print.
NOTE: Waste material that has not been automatically reclaimed should not be reintroduced into the system: it
could cause print-quality issues.
ENWW Material 45
You can store empty, partially full, or full reusable cartridges for later use.
Do not throw away the blue material cartridge cap. Storage for the caps is provided on the interior of the material
door. Any time you remove a material cartridge from the printer, be sure to put the cap back on.
Special care must be taken to avoid personal injury when handling heavy cartridges.

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 on the front panel 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 the
printer’s environmental conditions for at least 2 days.
CAUTION: HP recommends storing only capped cartridges. 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 printer or severely damage it. Placing the cap back on the cartridge
is necessary for storage to prevent material from spilling; if excess material is lost, the cartridge may not be
recognized by the printer because it is considered to have been tampered with.

In the event of an error, the printer cancels the job immediately.
Proceed with retrieval if relevant.
NOTE: The printer needs to cool down before unlocking.
ENWW Check status remotely 55
11 Cooling and part retrieval
At the end of printing, a cooling period is required. After cooling, unused build material will be reclaimed
automatically unless previously disabled within HP SmartStream 3D Build Manager. Light vibration and airow
will remove unused build material for later reuse. Following material reclamation, the front panel noties you
that parts are ready to be retrieved.
Parts may be retrieved early, after a safe cooling period. Early retrieval may degrade part quality and is not
recommended. The top cover will remain locked until parts have reached a safe temperature.
NOTE: Parts will still be hot to the touch. Safety gloves are recommended.
If any residual material remains in the build chamber after parts retrieval, there is an option to perform additional
reclamation.
Part retrieval
1. Tap Retrieve parts or Finish build in the build status app.
2. Open the top cover.
3. Use the up and down buttons to raise or lower the platform to make the part retrieval process more
convenient.
CAUTION: Tall, vertically-oriented parts could fall over and become wedged while the platform is being
raised. If this happens, stop and rearrange parts before continuing to raise the platform. The printer may
disable further platform movement until the next job.
CAUTION: Wear safety gloves. The parts may be hot.
4. For optimal part and color quality, remove each part with all attached material. Do not allow any excess
material to fall back into the build chamber.
The examples below show a part with attached material when removed from the build chamber, and the
same part after bead blasting.
56 Chapter 11 Cooling and part retrieval ENWW
CAUTION: Do not brush or forcibly scrape loose material attached to the parts back into the build
chamber.
5. Continue until all parts are retrieved from the build chamber. Use the buttons to lift the platform to reach
all parts.
CAUTION: If you see colored material in the build chamber, use an explosion-protected vacuum cleaner to
remove this colored material, so that it will not be reclaimed and recycled in future builds.
6. After parts have been removed from the printer, additional cleaning with hands or a brush may be used
before bead blasting. This will preserve the color of the nal parts as well as the lifespan of the beads and
lters. This material may not be returned to the printer as it will compromise the part quality of subsequent
builds.
7. Material may remain on the build platform. Additional reclamation may be initiated by pressing the Reclaim
and Finish button.
NOTE: All doors, and the top cover, must be closed before starting to reclaim material.
CAUTION: Do not reclaim material that has been fused or colored.
NOTE: Some material may remain at the edges or frame of the platform.
Once the front panel tells you that the process has nished, you may want to check whether all material
has been reclaimed. To remove any remaining material, use an external explosion-protected vacuum
cleaner.
8. With all parts clean and excess material reclaimed, resume normal printing.
ENWW 57
Keeping the printer clean
If a signicant amount of material falls from the top cover after a build, the following precautions may be useful:
1. Tap along the front of the top cover before opening it.
2. Slowly open the top cover about 25 cm (10 in), and use an explosion-protected vacuum cleaner with a soft-
brush nozzle to remove material from the edge of the cover.
3. Continue opening the cover slowly, without releasing it, until it is fully open.
4. Vacuum the interior surface of the cover to remove any remaining material.
5. Place a vacuum hose near the top of the build chamber to remove dust during parts retrieval.
58 Chapter 11 Cooling and part retrieval ENWW
12 Post-processing
Once parts have been retrieved from the printer, they should be cleaned of excess material. HP recommends
removing loose excess material and large clumps of material from each part before bead blasting. This will
preserve the color of the nal parts as well as the lifespan of bead-blaster lters and glass beads. After this loose
material is removed, the remaining material will have to be removed in a bead- and air-blast machine. All parts
should be bead blasted (rst) and air blasted (second).
● Bead blasting consists of applying compressed air mixed with an abrasive material to the part in order to
remove the attached material.
HP recommends blasting parts with glass beads of diameter 210–297 µm (50–70 mesh).
● Air blasting consists of applying compressed air to the part in order to remove any material remaining after
bead blasting.
The following options are available for color-related nishing:
● Dyeing: The part is immersed in a controlled dyeing bath. All details and cavities of the part can be reached.
● Painting: The part is painted with a 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.
Depending on your specic needs, other postprocessing methods may be suitable for you, including:
● Hand sanding: The surfaces of the part are smoothed by abrasion with sandpaper
● Clear coatings for wear resistance, water resistance, gloss, and so on
● Gluing, bonding, and sealing
● Drilling, tapping
● Coloring of monochrome parts, including dyeing and painting
Contact your service 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.

roll needs to be replaced.

prevent the printer from keeping track of roll usage, in which case you may see incorrect error messages, and a
