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.
