Unlike PVA our DPA-100 is less sensitive to moisture uptake and offers better shelf-life and print performance over time. It is a Dissolvable Polyacrylate material made to work specifically with engineering grade materials which are not suited for PVA, like PETG, ABS, ASA, PC and PA filaments. We have extensively tested DPA-100 on various 3D printing materials available in the market, both colorFabb and non-colorFabb branded.
DPA-100 is also perfectly suited for our range of co-polyester filaments: nGen, colorFabb_XT, colorFabb_HT and PETG Economy.

How to dissolve
Printing with DPA-100 is the first step. Dissolving the material is the second one. In order to dissolve DPA-100 you need a mild alkaline solution which is heated and stirred. At higher temperature DPA-100 will dissolve faster than at lower temperature. The temperature you choose depends on the temperature resistance of your build material. In general 20c below the temperature resistance of your build material is a safe settings. Thicker models would be less likely to deform and can handle temperatures closer to softening temperature. The minimum pH value for the alkaline solution is >10. We recommend using our DPA Detergent for making the alkaline solution.
The DPA Detergent is sold seperately from the DPA-100 filament.

The detergent, dissolved in water, produces a mild alkaline which usually, together with the dissolved support material, can (in limited quantities) be disposed of via the wastewater. Please check your local regulations. You can acquire our waste profile datasheet by contacting email@example.com
