White Powder; White Sandstone texture; 3D Printing Architectural & Industrial Design; ZCorp 650 / 3D Systems Projet 660 full colour 3D printing system
- White Powder Based Composite material is composed of fine granular gypsum-based powder
- 3D printing technology with high resolution up to 650x540 DPI
- Fastest and most cost effective method to produce presentation models
- The final product is hard and slightly brittle similar to porcelain, so is fragile (please be careful when handling)
- Surface has a sandy, granular finishing due to the powder based technology
- This material allows for maximum design freedom as it does not require additional support material
Ideal for conceptual design presentation / mock-up models for design evaluation purposes, which don't need to be functional or exposed to high stress or heat.
3D Systems Projet 660 3D printing system. The printer builds up the model from bottom to top, layer by layer in 0.1mm thickness. A roller puts a thin layer of powder on a platform and a print head places tiny drops of glue at specific locations, printing a thin layer of your model. The platform lowers and the roller spreads another layer of powder. After the printing process the model is brittle, but is strengthened by a superglue-like finishing liquid.
Summary of Projet 660 3D Printing and Post-Processing Steps :-
1) Powder 3D printing
The white powder 3D printing process uses glue to bond together layers of fine powder material. First, a thin layer of fine powder is placed across the 3D print platform and a print head sprays tiny drops of glue at specific places, printing a thin layer of your model. After each layer, the 3D print platform is lowered and this process is repeated thousands of layers until the object is completed.
2) Post 3D Printing Process - Removing Parts from Powder Block
After the 3D printing process, the 3D printed objects are carefully removed by hand from the excess powder that acts as self-support during the 3D printing process. A portion of the excess powder that was not glued together during the 3D printing process is recycled back into the 3D printer for future use.
3) Post 3D Printing Process - Fine Powder Removal
The 3D printed parts are then further cleaned using pressurized air, removing the remaining fine powder after which the 3D printed parts take shape.
4) Post 3D Printing Process - Surface Finishing Application
After the 3D printing and fine powder removal processes, the 3D printed parts are still fragile and brittle, but is strengthened by a superglue-like finishing liquid which further solidifies the object. And finally the 3D printed objects are given an anti-UV varnish to add further protection from extensive light exposure.
