PMMA Filament

Acrylic / Plexiglass / Perspex

C
Also known as:AcrylicPlexiglassPerspexLucite
Family:PMMA

Why Use PMMA?

  • Best-in-class clarity; can be buffed/frosted/polished
  • Good UV resistance
  • Clarity and rigidity for display parts

Things to Consider

  • Terrible bed and layer adhesion; high thermal expansion; brittle
  • Prints often fail during/after
  • Can crack/warp; requires tuning

Safety & Ventilation

  • Print PMMA in a well ventilated area. Higher-temperature materials like this can release fumes and fine particles while printing. An enclosure improves print quality and helps contain fumes, but it is not a substitute for fresh air, so vent the enclosure or run an air filter and avoid an unventilated occupied room.
