Clear, near colourless, durable, water-resistant resin for stereolithography for solid state laser systems
Nearly colourless, low viscosity liquid photopolymer that produces strong, tough, water-resistant, ABS-like parts.
Clear parts can be machined in either Acrylic (PMMA) or Polycarbonate (PC). Both materials give an excellent result when polished with a high level of clarity.
Large parts can be fabricated and joints concealed or made with clear adhesive.
When prototyping lenses this results in a good approximation of performance in advance of manufacturing mould tooling.
PC is the harder of the two materials and the preferred choice if scratch resistance is an issue.
Vacuum casting materials are generally polyurethanes (PU’s). The range of materials is huge and there is a large subset that offers clarity.
Achieving clarity is a function of the material chosen and the tooling. Even a water clear resin will appear translucent if the tooling is textured. Hence clarity requires the selection of the correct material and that any masters used to create the tooling are dressed to a high gloss finish.
Materials can be tinted.
The best advice is to contact Plunkett Associates with the following information, and we will identify suitable materials.
- areas requiring clarity (or whole part)
- any environmental requirements, especially temperature
- aesthetic requirements, tinting, printing
