structur3d / discov3ry paste extruder

Recommended Posts



I found the project on KickStarter :


It's an universal paste extruder who will work with any FDM 3D printer with stepper motors. What's your opinion ?


Someone have experience with paste 3D printers ? What kind of paste works well ?

The new head can be too heavy for the actual UM/UM2 head ?

What about the slicer ? Who control the extruder ? Will it affect the UM/UM2 long term reliability ?


Thanks for comments

Already have an Idea, for multiple sizes and up to 2 syringes (2 component resins maybe?)

Pretty simple; 2 linear guide rods + bearing, a lead screw + nut and a stepper motor for mechanical parts. Rest could be printed. We just need to ad an auxiliary plug to an 4 pole double throw switch, so you can choose the original extruder, or the aux. output

But... there's probably already a few out there?

    • Taking Advantage of DfAM
      This is a statement that’s often made about AM/3DP. I'll focus on the way DfAM can take advantage of some of the unique capabilities that AM and 3DP have to offer. I personally think that the use of AM/3DP for light-weighting is one of it’s most exciting possibilities and one that could play a key part in the sustainability of design and manufacturing in the future.
