Shapeways says their acrylic family of materials will now include Frosted Extreme Detail and that signals the end of what they call Frosted Detail material on April 29th. The problem? Frosted Detail printed fully enclosed in support material which required that the enclosure be cleaned away, and that process was wasteful, expensive, and presented difficulties in production. But the company says Frosted Extreme Detail “offers the highest detail of any of the materials we offer and can be used for the most detailed miniatures, and models like molds and mold masters where very smooth surface finish is critical.” FXD utilizes a waxy support material which is dissolved once the printing process is complete. FXD is printed using the Multi-Jet Modeling (MJM) process where molten plastic is deposited onto the build platform in layers using several nozzles.
