Multimaterial

The FDM printing is not just one of the slowest 3D printing processes, it also lacks accuracy and requires support structures. But in some aspects they can still exceed High-end printing processes such as selective laser sintering or polyfusion. While these processes are able to produce accurate Parts consistently, they struggle when it comes to material diversity. And thats when FDM shines, you can print almost any thermoplasts like PLA, ABS, ASA, TPU, Nylon, PEEK and even Polyimide – which can withstand crazy temperatures. But the best part about it, these Materials can be combined.

Printsize

300x300x240mm ( XYZ)

Exchangable Toolheads

Tiny tools can be picked up at any stage of the print

Shared Watercooling

The tool bank and X-axis are water-cooled and cool the tools passively when docked.

Hybrid Extruder

The Tools are small and simple, additional tools stay affordable

Slim tool design

Due to the narrow tools, motorized and complicated tool changers can be dispensed with.

Hybrid Toolhead

Small bowden driven switchable tools along with a permanent direct drive Extruder

The extruder is based on an optimized Bondtech BMG, but the distance between the hot end and the extruder has been shortened compared to the original. The dual drive gears, along with the shortened gap between hotend and drive gears makes the extruder particularly suitable for precise printing of flexible materials.

  • Water Tubing
  • Filament Channel
  • Spring Loaded Extruder
  • Kinematic Tool Coupling
  • Endstop
  • Mastercooler
  • Hotend T0
  • Fan
  • Tool Retainer
  • Passive Cooler
  • Hotend T1

Kinematic Coupling

The tool is exchanged between toolbank and X-Axis by a retainer, along with a tetrahedron-vee-flat coupling system ensuring repeatable accuracy

Detachable Fans

The fans are Slide locked into the Extruder and can easily be detached for unrestricted access to the hotend

Dual Filament Drive Gears

Dual drive gears and short gap between hot end and drive gears ensures uniform extrusion, even with flexible materials

Belt tensioner

Belt tensioning is especially crucial on core XY machines

Silicone leak blocker

Silicone wiper prevent material oozing from the inactive extruder

Offset Tools

The tools are slightly offset to ensure safe operation and prevent oozing into the print
