UV Light Safety
This product uses a light engine that outputs ultraviolet light in the UV-A range, with possible trace amounts in the
UV-B range. This product is compliant with the international standard ISO 3059:2012 in accordance with non-destructive
penetration testing of UV irradiance. This product encloses the light engine in opaque and UV-filtered material to
prevent UV light exposure. However, incidental UV light may extrude from the machine due to any of the following:
• Leaving the door open during usage
• Gaps or holes in the sides of the machine
• Transparent or translucent resins
During operation, do not stand near this product for prolonged periods of time, and do not look directly into the lighted area. Improper
exposure to UV light can cause painful eye and skin injuries.
UV Protective Gear
Prolonged Exposure
UV light exposure is most potentially damaging to the eyes. Wear UV-filtered glasses, goggles, or a
face shield to protect your eyes from the damaging effects.
Eye Protection
Thick Clothing
Other areas of the skin may be exposed, especially if the product is used in cramped environments.
Wear long-sleeved shirts with collars, long pants, and even cloth hats to protect your skin from
incidental exposure.
Skin Protective
Substances
Topical agents such as sunblock, sun cream, or similar substances can protect against the effects of UV
light, but these are generally designed for outdoor use. Do not rely on such substances in lab
environments, but use them as an extra layer of protection if necessary.
Gloves Skin exposure is most likely on the hands, which are oftentimes closest to the product during operation.
Wear thick cloth or rubber gloves to protect your hands from UV exposure.
Direct UV-A light into the eye can lead to irritation, temporary blindness, and the forming of cataracts
on the lens of the eye. UV-B light can compound the cataract-forming effect, and can also lead to
photokeratitis and photoconjunctivitis.
Eye Exposure
Skin Exposure Direct UV-A and UV-B light on the skin can cause localized tanning, burning of the skin, and can lead
to skin cancer in extreme long-term situations.
Resin Safety
Resins provided by Ackuretta are non-carcinogenic acrylic-based photopolymer liquids that give off a light odor. These
resins may cause skin, eyes and respiratory system irritation, and skin sensitivities or allergic reactions by skin contact.
Inhalation of a high high-vapour concentration may cause headaches and nausea. Ackuretta recommends the
following protective gear when handling photopolymer resins, whether from Ackuretta or from another company:

Resin Protective Gear
The hands are the most likely affected area when handling resins. Wear rubber, nitrile, polyvinyl
chloride, or other chemical-resistant gloves.
Gloves
Face Mask or
Respirator
If the room does not have sufficient ventilation, wear a respirator or medical face mask to protect
against inhalation or accidental exposure to the mouth.
Thick Clothing
Prolonged exposure to resin may cause irritation or may cause allergies to develop where they
previously did not seem to occur. Wear long-sleeved shirts with collars, long pants, and even cloth
hats to protect your skin from incidental exposure.
Eye Protection While using air compressors or due to usage or handling, resin may splash into the eyes. Wear protective
goggles, safety glasses with side shields, or a face shield.
Acute Exposure
This product may cause skin irritation. Symptoms may include a slightly localized redness or rash and
swelling. Repeated exposure may cause sensitization and allergic skin reaction in some individuals
resulting in contact dermatitis, severe irritation, dryness and cracking.
Skin Contact
Inhalation
This product is a suspect slight respiratory tract irritation hazard, especially if used at elevated
temperature or processes which may generate aerosols or mists. Symptoms of irritation may include
coughing, headache and nausea, mucous production and shortness of breath.
Ingestion
This product may be harmful if swallowed. It may cause nausea, headache, vomiting, diarrhoea, and/or
central nervous system effects. Keep all food in an area separate from storage and use locations.
Prohibit eating, drinking and smoking in areas where there is a potential for significant exposure to this
material. Thoroughly wash hands before eating.
Eye Contact This product may cause eye irritation. Symptoms may include excessive tearing, itching, irritation,
blinking and redness.
Chronic Exposure
Prolonged contact may cause sensitivities and allergic reactions. People with pre-existing skin conditions
may incur more significant irritation. Repeated exposure may cause sensitization and allergic skin
reaction in some individuals resulting in contact dermatitis, severe irritation, dryness and cracking.
Skin Contact
Inhalation Prolonged or repeated overexposure may cause irritation, headaches, and nausea.
Ingestion Prolonged or repeated swallowing may be a slight ingestion hazard. Chronic ingestion of high doses
has shown damage to testes in studies with animals.
Eye Contact Prolonged contact may cause redness of eye tissue.

Resins provided by Ackuretta are not readily biodegradable. Releasing these resins into the environment may be illegal according to
the regulations in the usage area.
* Properly dispose of resins in accordance with all applicable federal, state, and local regulations.
For more information, please refer to the Material Safety Data Sheet for your particular resin.
Disposal
To clean prints, Ackuretta recommends using solutions of 95% ethyl alcohol or 95-99% isopropyl alcohol (IPA). Both compounds are
colorless, transparent, and naturally give off strong odors. Both compounds have the following major safety concerns:
•Highly flammable and potentially explosive.
•Toxic and can cause adverse conditions from ingestion, inhalation, or direct contact.
•Evaporate quickly so they can become an airborne toxins.
Adverse conditions may include:
Skin Contact This product may cause skin irritation. Symptoms may include skin discoloration, dryness, and cracking.
Eye Contact This product may cause eye irritation. Symptoms may include excessive tearing, itching, irritation,
blinking and redness.
Inhalation This product is a suspect slight respiratory tract irritation hazard. Symptoms may include nose, throat,
and lung irritation, coughing, and/or shortness of breath.
Ingestion This product may be harmful if swallowed. It may cause nausea, headache, vomiting, and/or
unconsciousness. It can also affect concentration and vision.
Chronic Exposure
Skin Contact
Prolonged contact may cause sensitivities and allergic reactions. Repeated exposure may cause
sensitization and allergic skin reaction in some individuals resulting in contact dermatitis, severe
irritation, dryness and cracking. Alcohol can be absorbed through the skin and may result in
symptoms similar to those listed under acute ingestion.
Eye Contact Prolonged contact may cause redness of eye tissue.
Inhalation Repeated high exposure may affect the liver and the nervous system.
Ingestion
Occupational exposure is unlikely to cause cancer, but direct and repeated ingestion may increase
the risk of liver, esophagus, breast, prostate, and colorectal cancers. Pregnant women should not
ingest alcohol, and repeated exposure may cause spontaneous abortions, birth defects, and other
developmental problems. Repeated ingestion may also reduce fertility in males.
To avoid these potential issues, do the following:
•Store in cool, dry, and well-ventilated areas.
•Label containers with instructions regarding handling and storage.
•Keep away from any sources of heat, fire, and sparks.
•Keep away from strong oxidizers, acetaldehyde, chlorine, ethylene oxide, acids and isocyanates.
•Close containers tightly with a strong seal immediately after use.
•Dispose in accordance with all applicable federal, state, and local regulations.

Consider the following when choosing where to set up your FreeShape 120 and your printing work space.
3. Setup Environment
4. Calibrating Your Build Platform
A. Temperature: 18°- 25° C
Keep your printer and your resins in a dry, temperature-controlled room around 22° C (72° F).
Resins become more viscous when they are too cold. If the environment is around 15° C (59°
F), Ackuretta recommends increasing all curing times by 15%. Even colder temperatures may
require increasing curing times further or may cause print failures.
Similarly, resins may become very thin in hot temperatures. If the environment is hotter
than 35° C (95° F), resins may overcure or may melt during the print process.
B. UV-Filtered Lighting
The UV-protected hood of the FreeShape 120 protects the resin from outside lighting while
the hood is on the printer. As you use the printer, the door will be opened many times, and
the resin will be exposed to outside light.
To protect the resin, set up the printer in a place where the lighting is controllable or covered
by a UV filter. Similarly, use the same UV filtering in your finishing space and your resin storage
location.
C. Ventilation
Resins and cleaning alcohol evaporate over time like all liquids. These substances
can be corrosive to other equipment and may be harmful if inhaled over a long time.
Keep your printer, resins, and your cleaning work space well ventilated at all times.
Avoid lingering in the same room with uncovered resins for a long period of time.
Adjust the fit of your FreeShape 120 build platform when you first open your machine. If you do not calibrate your
build platform, your prints may be uneven, or you may encounter print failures. After calibrating once for the
machine, you do not need to calibrate your build platform again, unless you use it on a different FreeShape 120,
or unless you purchase a new build platform.
Start your build platform calibration with a dry, clean vat and build platform.
FreeShape 120 Manual
