SUP706 will dissolve into the caustic soda and sodium metasilicate
solution and saturate it, reducing its effectiveness. Replace the solution
when the Support material reaches 20% of the solution (after
approximately one month of average use).
Warning
Caustic soda may cause chemical burns, scarring and blindness. Mixing it
with water generates heat that could ignite other materials. Never pour
water into caustic soda. When diluting the solution, always add caustic
soda to water. Take adequate safety precautions; always use nitrile
gloves when handling caustic soda and models soaked in it.

Post-Printing Treatment for Models Made with VeroClear

Models made with VeroClear (RGD810) have a slight yellow tint when
removed from the printer. This is especially true for models printed with a
glossy finish. The yellow tint fades naturally over time, but you can greatly
accelerate this process by using a suitable photobleaching treatment.
As a rule, best clarity is achieved when parts are printed with a matte finish,
and treated as explained below.
Photobleaching models involves exposing them to light. To achieve highly
controlled and predictable results, a professional illumination chamber is
recommended. However, adequate results may be obtained using ordinary
desk lamps fitted with suitable fluorescent elements.
