installing, operating, maintaining and inspecting.

- It is designed to help ensure your own personal safety and to help protect your
equipemnt from potential damage.

- Failure to observe the safety notes may lead to serious injuries and to significant
damages to the system.

! Place the machine in well-ventilated place due to smell of the resin.

! Do not insert tools or parts of body into machine during the printing process.

! Never look directly into light beam in order to protect your eyes.

! Never use gasoline for printing. Please keep it away from the machine.

Also, 3D prints or resin residue shouldn't be swallowed, as It could causedisorientation

and suffocation.

! Stop the printer from processing and take the resin tank out not to overflow resin. and

then turn off the machine and move it.

! Do not turn power switch off when it's on. It reduces life span of engine and could be

one of errors. Get it ended as given in manual

! Putting some of liquid or metal pieces into printer is harmful for fire disease or

electric shock. Also, Do not operate the machine with wet hands protecting from fire or
electric shock.

! Do not ruin main power of printer. Neither change or ruin USB cables or supply power

raised from outside.

! Carefully choose place for installation protecting from pet or child injuries made by

printer

! Standard accessories include sharp tools such as cutter or nipper. Be careful not to cut

yourself on any sharp edges.

! The space inside machine is designed to be taken up by light of engine.

please do not insert anything else inside.

! Protect the machine from dampnes, such as rain and now, and dusty weather.

! Install and operate the machine on a flat level and dry surface. Kepp the machine away

from flammable liquids, gases, and aerosols.

! Do not impose excessive force on the machine.The external housing of your machine

may be damaged Also, Read all instructions before using the machine.

Use of resin

! Be careful about resin from contacting skin or body part.

- If in contact, rinse in running water and make sure to wear gloves during work.

Replacement of resin

Lifetime of optical engine

3

! Remove alien substances and scraps at the bottom of tray.

- Remaining scraps may have adverse effects on the output.

! After replacing resin, stir well before use since precipitates can be formed.

Cleaning of build plate and tray

! Check for alien substances and scraps on build plate and tray every time.

- Remaining scraps may have adverse effects on the output.

- Regular management and cleaning of tray are necessary.

! Coating can be damaged if the tray is cleaned with a sharp object.

- Use a spatula or dry cotton cloth as cleaning tool.

! Poor cleaning can lead to poor quality of output and lifting or cracking of floor.

Lifetime of optical engine lamp is 3,000 ours, and brightness of the lamp can be
reduced by exceeding its lifetime. Replace the lamp after using it for 3,000 hours
to increase quality of output.

Preparation for A/S request

Record error situation, interior of the printer, and LCD display as photograph or

Build plate lock knob

Build plate

Build plate handle

Loosen

When printing is done, loosen the build plate to detach it by rotating
build plate lock knob counterclockwise. Grab build plate handle and
take out. Reverse the order when attaching the build plate.

Precaution

When detaching the build plate, resin on the build plate may fall off or
spatter over the exterior or equipment to damage or contaminate the
equipment. After removing output, the build plate must be wiped out
cleanly to remove any remaining resin.
Resin left intact for long time can harden and affect output.

How to Refill Resin

9

Resin

Refill resin as shown in the figure.

Precaution

If possible, refill resin before printing. If it is inevitable to refill resin

while printing, press “pause” button and slowly add resin after the

work comes to a complete stop. Refilling resin while printing can
result in foams that have adverse effects on output.

Amount of Resin Refill

Standard

Shell

In general, we recommend filling resin between shell line (250g) and
standard line (500g). Do not exceed max line (800g) when printing
large output.
When filling resin above the max line, resin can flow over the tray with
up-down motion of motor depending on shape of output.

VAT Check

11

Surface of VAT sheet shows holes, ripping and loosening. These
are natural phenomena that appear when it is used for long time.
When the sheet surface has hole or ripping, resin will enter into

the hole or ripping and result in printing failure. Attach a new VAT

in this case.

This appears in short time if surface of the sheet is scratched by
output or hardened scrap made carelessly by the user.

Ch3. System Control

3) Print Setting Know-how

1. Exposure time refers to time during which output image is exposed in the
optical engine when printing a layer. Long exposure time causes over­hardening of output and short exposure time causes under-hardening. It is
necessary to enter accurate time for resin being used.

2. Initial exposure time should add 1~3 seconds to default exposure time.

3. If ‘Movement of Build Plate While Building’ is short, building time is
shortened. If movement distance is too short, it can have adverse effects on
output. This distance is 5~15mm in general.

4. ‘Movement of Build Plate After Building’ refers to distance by which the
build plate it lifted automatically after building. Value of 40~60mm is most
convenient.

5. Split exposure time refers to time that splits exposure time. Since light of
the optical engine contains high energy, long-time exposure has adverse

effects on the tray. Therefore, setting of split exposure time can lessen damage

on the tray. Value is 3~5 seconds in general. This function is deactivated by
setting split exposure time to 0.

Precautions for Post Work

Preparation for post work: Materials (cutter blade, spatula, cleaning
alcohol, pincers, toothbrush)

<Precautions>

- Use of cutter blade: The mold can be damaged if taken off by hand or
ordinary knife. The build plate can be damaged if it adsorbs strongly
to the build plate.

- Alcohol: Only use pure ethanol. Never inhale alcohol since it is
hazardous.

- Air compressor: Use an air compressor with 1 horsepower or above so
that remaining residues can be wiped out sufficiently. If the
compressor is not ready, dry alcohol completely at room temperature.

- Cleaning time: Since the mold can be deformed if immersed in alcohol
for long time, make sure to clean it quickly after detachment.

- Hardening time: Hardening is done in about 10 minutes since
secondary hardening (UV hardener) can cause bending or deformation
of thin mold.

- Treatment of waste after printing: Wastes are separated into liquid and
solid. Liquid is entrusted to a waste treatment company, and solid is
treated as general waste. (Refer to the back page)

37

Take the mold out and place it on the work
table.

Use the cutter blade to remove the mold from
the build plate.

Remove remaining resin cleanly using alcohol.
Use a toothbrush with thin hairs to clean gaps
between.

Since the mold can be deformed by alcohol,
use the air compressor to clean it.

Dry the cleaned mold using the UV hardener.
Since light of the UV hardener is extremely

intense, make sure to wear protective

equipment before using it.

Handling Resin Waste

1. Overview

Method of safely managing and lawfully handling chemical
substances and general wastes generated while using the device
according to environmental safety regulations

2. Type and Definition of Waste

1) Wastewater from cleaning of output
Wastewater generated when cleaning liquid resin on output

2) Output waste
Solid waste generated from printing of output

3) Hazardous waste (liquid)
Waste resin liquid remaining after printing of output

3. Waste Handling Procedure

1) Wastewater from cleaning of output
It can be drained if there is a treatment system in the building. It
must be entrusted for treatment by a waste treatment company if the
building does not have a treatment system.

2) Output waste

Output waste and general wastes listed below are handled as
general wastes instead of entrusting to a company.

3) Hazardous waste (liquid)
It is entrusted to a waste treatment company in a way that general
wastes are not mixed with hazardous waste (liquid).

- Items below are handled as general wastes.
└ Household chemicals like soap and detergent
└ Solid wastes after printing
└ Toilet paper and paper without chemicals
