structur3d / discov3ry paste extruder

[si2w 8]

Hi,

 

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

You could make this yourself, not that difficult; Looks like they just use a stepper driver actuator emptying a syringe.

Could be made in a nice Youmagine (collab) project :mrgreen:

I do have already some steppers configured for working with syringes, I'd be interested in co-opping with someone to finalize the design Anyone? Dieselpower maybe?

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?

I might have something cool to show you then, will post a picture as soon as i get home (might take a while )

I'm sure I've seen at least one design on Thingiverse for squirting chocolate and similar substances.

Well... there's lots of them to be honest
