UV Resin for DLP and DUP 3D Printers
The 3D printing processes DLP, DUP or SLA are based on the layer-wise polymerization of UV sensitive resins. The resin, based on acrylate or epoxy polymeres, are filled in a vat (or tank) whereas the UV light is impacting from a transparent bottom (of glass or acrylic) the resin liquid when bottom-top-printers are used like the Milkshake3D or Gizmo. Mostly such vat bottoms are coated with silicone or other elastomeres. Also, quite commonly now, FEP sheets are introduced as separating layer between the resin and the actual light source (beamer or display). Top-bottom printers use different vats to allow the light impacting from on top of the surface the resin.
DruckWege Resin for DLP and DUP 3D Printers
The UV sources in all cases are in the range of UV A spectrums, quite commonly 405 nm. The reactive resins are shaped at sensitivity to match the light fractions peaking at such wavelength.
Since 2017, DruckWege offers its own brand of 3D Printing Resins, developed and manufactured in Germany.
3D Printing Flexible and Hard Resins
Our high quality resins are epoxy based with industrial specs, designed for 3D printers with DLP and DUP UV light sources. Our own brand is very durable, easy to paint and has some outstanding physical properties:
- quick curing times
- high degree of details and sharp edges
- smooth and dry object surface
- VOC free
- viscosity: 33-57 mPa/s
- shrinkage: ca. 2% +/- 1%
The degree in hardness of the surface and material itself depends on the choice, whether you decide for our general Type D resins for modeling and prototyping or our functional resins, such as our Type D PRO line, including flexible materials.
