Handling
Printing
Materials
Printing materials (resins) are flammable –Do not expose them to flames, heat or
sparks.
Keep resins away from food and drink.
Uncured resin is toxic - minimize direct contact with the skin to prevent irritation
and other health hazards. Prolonged contact may cause burns.
Always wear protective gloves.
First Aid for
Working with
Resins
If respiratory irritation occurs, expose the victim to fresh air immediately.
If uncured resin comes in contact with the eyes, flush immediately with large
amounts of water for 15 minutes and seek medical attention.
When handling resins or material containers, wear protective goggles to
prevent uncured resin from splashing into the eyes.
If uncured resin comes in contact with the skin, wash the area immediately with
soap and cool water.
General Safety
Rules
Be familiar with the locations and use of safety equipment.
Do not use broken equipment. Machinery with moving parts must have a working
safety interlock, and a protective cover over the moving parts.
Do not open the cover while printer is operating.
If open, do not stare at the UV light and use protective eyewear to prevent exposure to
UV light.

MATERIALS
OVERVIEW

2STRATASYS / MATERIALS OVERVIEW
•PolyJet materials are acrylic-based photopolymers
•Photopolymer is a polymer that cures, or becomes solid, when exposed to light.
(in our case: UV light)
•When exposed to UV light the material is transformed from a soluble formulation
into a hard polymer network –the model!

10 STRATASYS / MATERIALS OVERVIEW
Special Considerations:
•For best clarity print in matte, photo-bleach for 6 hrs., polish and lacquer the part.
•When glossy is necessary, photo-bleaching is with extreme importance to achieve the best color
& transparency.
•Minimize the number of models on the tray
•Thinner walls are clearer
•Assure a clean printing block area
•When switching from different material preform high performance material replacement
•For additional information refer to VeroClear RGD810 application note
Transparent | VeroClear RGD810

11 STRATASYS / MATERIALS OVERVIEW
•Models made with VeroClear RGD810 have a slight yellow tint when removed from the printer.
•Models with a glossy finish have a stronger tint than those with a matte finish, due to the
longer UV exposure.
•This yellow tint fades naturally over time.
•Photo bleaching treatment accelerate the process and reduces the yellow tint.
Transparent | VeroClear RGD810
Significant reduction of yellowing was obtained by exposing models to
fluorescent lighting while heating to 40ºC for a six-hour period.

12 STRATASYS / MATERIALS OVERVIEW
When removed from the build tray, Objet VeroClear models may have a slight yellow tint which will
fade over time. You can greatly accelerate this process by using a suitable photobleaching treatment.
Photobleaching- Suggested Methods
Illumination Chamber
•Off-the-shelf chamber
•Enables controlling
temperature and light intensity
assures predictable results
•Self-assembled from available components
•Low cost solution
•Varying results, due to the lack of precise control
over temperature and light intensity
Cost:
Approx. $1,300
Cost:
Approx. $50-200,
depending on the
number of lamps used
Table lamps
There are 2 suggested photobleaching methods:

13 STRATASYS / MATERIALS OVERVIEW
6 hr ~70% improvement in clarity
24 hr ~90% improvement in clarity
Over 24 hr Additional improvement (minor )
Before treatment Photobleaching

Photobleaching Results

14 STRATASYS / MATERIALS OVERVIEW
Photobleaching with Table Lamps
Cover the inside of a container with aluminum foil.
1
Arrange the printed models in the container with enough distance
between them to allow light to reach all sides of each model.
2
Prepare two table lamps with 45W, 6500K fluorescent lamps.
3
Position the lamps on the table, approximately 10 cm (4”)
above the models. This distance prevents the lamps from warming
the models above 40ºC (104ºF)
4
After 6 hours, inspect the models. If the results are still not satisfactory,
leave the models in the chamber for up to 18 hours more.
