The brief

Analyst view
  • Put professional resin printing on the desktop with Form 1 (2012 Kickstarter), then powder printing with Fuse 1.
  • Form 4 (2024) hardens a whole layer at once with an LCD screen, several times faster than Form 3.
  • Last priced round: $150M at $2B in May 2021, led by SoftBank Vision Fund 2.

Technical approach

As reported
Resin

Whole layers at once (Form 4)

A bright light shines through an LCD screen that masks each layer's shape, hardening it in one go instead of tracing it with a laser.

Powder

Benchtop SLS (Fuse)

A laser fuses nylon powder layer by layer; loose powder holds the part up, so no supports are needed.

Materials

Own materials

Formlabs makes its own resins, including dental-safe ones, and tunes settings for each, so non-experts get repeatable results.

  • Real end-use plasticsActive research

    Resin parts are often weaker than molded plastic against heat, sunlight and long-term load.

  • Cheap competitorsOpen

    Low-cost Chinese resin printers undercut on price, so Formlabs must win on reliability and materials.
