Used For

  • Very Complex Plastic Parts
  • Very Precise Plastic Parts
  • Ultrafast Print Speeds
  • Better Structual Properties than Unannealed FDM Prints
  • Multiple small parts in large batches (possibly utilizing a batch box)
  • Printing without needing a filament maker; only a plastic powderizer is needed

Industry Standards

Existing Open Source Designs

Minimum Viable Product

  • Modular
  • Precise
  • Fast
  • Ultra Low Layer Height

Basic Design

  • A cube/rectangular prism is gradually filled with powder (precise layer by precise layer)
  • In between each layer being filled, a laser (moved either on a gantry or woved with optics) traces a 2D sliced image on each layer
  • This gradually buils up the object
  • The powder not used for the part allows for a built in support structure (unlike sla or fdm machienes)
  • Once done the part (and possible a printed part box") are lifted out and powder is brushed+blown+vacuumed away in a device similar to a sandblasting cabinet or laminar flow hood
