A fun and productive day at @cammakespace yesterday. Got the @ProjectFabMX extruder mounted to something that's starting to look like a printer... metal! 🤘 Lots of bugs found 🐛, some squashed, some turned to chrysalis awaiting more fervent attention 🦋

I received a nice surprise in the post today, the parts for the @ProjectFabMX extruder and a little bit of PolyMIM to play with! Thanks FabMX you can be sure we'll put this to good use at @cammakespace and I look forward to showing you a fully assembled extruder very soon 🚀

I persisted with #FreeCAD and now I am starting to get it! Started mocking up my idea for a @ProjectFabMX printer - take a @VoronDesign 2.4 frame, mount a bunch of Annex K3 thingys to it, and use them to sling a @Prusa3D Mini bed 🙃 Thanks for the tips @concreted0g!

The #Makespace #Cambridge is starting a "Metal Printing Club"! They are going to build a FabMX extruder and and a 3D printer for metal 3d printing. 🤩👍 meetup.com/makespace/events/…

*NEW* Metal Printing Club (members only), Sat, Mar 9, 2024, 2:00 PM | Meetup

Lets learn how to 3D print metal parts! The photograph on this event page is from the FabMX display at the Sanjay Mortimer Rep-Rap Festival last year. The goal of Project

New barrels for FabMX MIM pellet extruder v3.1

Only one. We get away with this because we have a special profile in our barrel to get the right temperature distribution. It's less flexible but also simpler+cheaper.

Interesting. What kind of extruder do you have?

You like printing steel, right? 🤓🛠️ This is one of the most exciting DIY projects right now. @cammakespace can you spare a little corner to give this hardware a home at Christmas time? 🥺 (oh, and lets have a filament recycling setup while we are at it... 💸)

We have released version 3.1 of our pellet extruder for MIM feedstock! See details on our wiki: wiki.fablab-muenchen.de/disp…

Consistent flow is always an issue with pellet extruders. But the simple extruder design we have is good enough for the MIM feedstock application. The parts we produce with PolyMIM have no visible defects due to inconsistent flow

Ah OK. Does this really have a noticeable effect? The screw turns really slowly, like 10 rpm

Gyroscopic?

How would a grid stop the flow?

I don't speak French, but if I can trust automatic translation you suggest a valve to cut off material flow, right? Yes, that would be a nice feature, but it is not so easy to implement I think and would make the extruder even larger

You add a NEMA23+gearbox and some smaller parts, and you have a working extruder! Anyone interested? Please join our discord to discuss the details. See fabmx.org/ for discord link.

And we are looking for beta testers! We will be able to provide barrel, extruder screw and laser cut metal cage for around 150 Euros (plus taxes, shipping, and if outside EU, possibly customs fees). These are the most important parts on the BOM (see link above).
