All About Acrylic Plastic

3D Printing Hub

Plasticizers are used as additives to improve impact resistance, lower glass transition temperature, or enhance processing properties. Electrical : Plastic optical fiber used for short-range communication is made from PMMA or Acrylic plastic. Hence, CNC machines are a good fit with acrylic plastics. Polishing and sanding may be necessary to remove any cuts marks or scuffs along the edges. Acrylic is not the strongest plastic and is actually quite brittle.

How to Finish Your PLA Prints – Easy Techniques

3D Printing Hub

PLA is made from corn starch, a fully renewable source, and is manufactured using less energy compared to petroleum-based plastics. Sanding. Any decent PLA finishing job starts with sanding. Sanding removes the outermost layer of PLA material, greatly reducing the number of visible ridges on the surface of the print. When sanding, it is important to maintain a circular motion so that the finish does not come out with a visible direction bias.
