Desktop Metal Fiber HT — Technical data

The Fiber HT was Desktop Metal's high-temperature composite printer. It combines filament printing with miniaturised automated fibre placement (µAFP): a tool changer with up to four tools lays continuous carbon or glass fibre tapes into a PEEK or PEKK matrix at up to 60 % fibre volume. The build volume is 310 × 240 × 270 mm. The HT version targeted low-porosity, flame-retardant, ESD-safe parts for service temperatures up to 250 °C, such as fixtures and lightweight components. Its sibling, the Fiber LT, works with PA6. Desktop Metal no longer offers the Fiber range, and no data sheet is available.

The Fiber was sold only by subscription with a multi-year minimum term. For a used unit, first clarify whether the seller actually owns it and whether software and print preparation work at all without a subscription. Then check the tools and heating system and the supply of the special fibre and matrix materials, which is hardly secured now that the range has ended.
