Multi-Material Printing - Spindle Sander Tool Holder

- I'm almost done fixing up my oscillating spindle sander, but I need a tool holder. I decided to make my first practical multi-material print, showcasing PETG+TPU as well as fiber laser marking.

Combining TPU and PETG is a single model, impressive.
Those laser markings are just beautiful.
I think so!
In PrusaSlicer, you can limit the depth of tpu using the maximum width of segmented region.
The regions painted at the side walls are expanded inwards up to maximum mmu_segmented_region_max_width (which is a new configuration parameter accessible in Print Settings->Multiple Extruders->Advanced).
I was thinking the same thing...
Yep, came here to say exactly this.
Thanks for enlightening me and others for that. Great find!
Very satisfying result Robert. Having success with new (to oneself) approaches always blows the mind to with what one can try next. Thanks for advancing the demonstrated capabilities for all of us 👍👍😎👍👍
It's rare when I come across anyone exceeding what I can do in my little shop. I've done multi-material on my enclosed XL, including nylon, and I've done embedded magnets. But with your fiber laser, man-oh-man have you ever changed the game. Sure, I could easily use some white PETG on the XL for the graphics, but I could never achieve the level of finesse that you are producing with the laser. Well done!
My exact reaction.
Next up: Fiber Laser head for the Prusa XL!
Magnets, lasers, and 3d printing you say? I'm in!
The defect is because of the infill being TPU in those areas it sags evvvverrr so slightly and then when you go to do a solid flat layer on top of the X pattern infill - the more solid material (PETG) doesn’t have the exact same support unilaterally underneath
That’s my best guess anyway!
Awesome project, and absolutely UNREAL that you got that spindle sander for $80…!! I agree, the motor is worth that alone
Cheers
Omg, I need that mini chop saw in my life... would have made several projects easier.... had no idea it existed.
Yeah that thing is in steroids.
Great practical use case! Love that you always give the little tidbits and lessons learned, as you go. Showcasing PrusaSlicer’s decisions when painting with TPU is great to know. The details on the temps to reduce stringing and the tolerances for magnets. This channel is gold.
For solidworks, instead of making a new part and assembly for multiple parts, I have found using multiple bodies works really well. It exports cleanly and the slicer recognizes the separate parts. Super easy for simple features. Just uncheck merge results in the extrude dialog
The final part with the engraving looks amazing!
Isn't it possible to make a few cylinders in PrusaSlicer and use them as modifiers for the multi-material setup (as they are used for support blockers/enforcers)?
I love me some Baldor motors. I've seen motors almost twice as old as myself come back to life and power critical equipment.
Excellent video, really liked how it all came together and the icing on the cake - the laser lettering. I always learn from my projects - some come out the way I intended, others have errors, but always learn something
Interesting. I've been having similar issues with my first layer on the MK4. Those diagonal underextrusions. I thought it might just be me.
Cool project! I would have replaced the larger spindles at the rear instead of the front that way you can grab and see the sizing easier.
Brilliant stuff, Robert! Very informative! Thank you! 😎👍🏻👍🏻
Nice 3D printing video but man, I'd love to see how you machined that part for the sander :)
Beautiful build, subbed
Thanks for the sub!
I have an E3D ToolChanger. When I print multi-material, I model the part in CAD with the softer material keyed into the harder material. Some of my earlier prints were not keyed into one another and could de-laminate over time and use. Keying the materials helped a great deal with that issue..
Regards
That's a great practical use for multi material printing!
but also that poor arduino getting showered lmfao 😭
Nice use of tools with a pro look to the finished product. 👍I gotta get me a laser like that! ❤
That's great!
Great job mate. Have a good one 👍🇦🇺
I am excitedly waiting for the video on the chop saw.
Ran into the same issues with underextrusion when using near the full diagonal length. Ended up rotating the part as far a possible, didnt think about decreasing volumetric speed. Thanks for the idea.
Just had the same finish issues on a voron with a e3d revo hotend. It was related to too fast a speed. Dropped speed a bit and finish cleaned right up.
I had the same issue with the paint on colour. In Fusion360 I just designed the different parts at the desired place and exported them either as STEP or 3MF. In Prusa slicer I turned the inserted parts into modifiers. So I have full control over the material, infill etc. If you paint on different colour (same material) you have no control over the infill. If one material is quite translucent, you will see the colour behind it. The solution with the modifiers solved my problem. I already issued a feature request a github for the Prusa slicer team. But no one seems to care about this...
Very cool idea! Anyone know if you can do this with a CO2 laser? Or does it have to be fiber?
This is brilliant. Thank you for such an iteresting use of multi material printing. Gives me a few ideas. Also, is the large amount of TPU infill due to you having the "wipe into infill" setting on?
You are amazing
Great video. I suspect that prusa slicer automatically created those large internal areas of tpu to "anchor" the tpu in place. A more elegant solution in the slicer would be helpful when using an expensive material.
I’ve noticed the weird addition to the amount of the other material is related to whether you paint or seperate model and which brush you use to paint
Can you point me to the electronics monitoring and managing the Bosch-Battery?
What do you use for solidworks? Old standalone version, their cloud version for makers etc.
I've been playing around with solidworks and multi material prints. I'm very disappointed there's no reliable way to export your bodies as individual STL files. I did find a macro to do it but there's an issue with it where you have to restart solidworks if you update your model and want to re-export.
Can you turn the Gothenburg into a filament respooling machine?
That part is the kind of thing that annoys me and I have to redo it because after putting it on the machine, I would have said - why didn't I print the lettering upside down on that side so so I can see it properly....a little thing, something not easily thought of before hand but something that would bug me every single time I looked at it...
There is no real 'front' I have the lettering mirrored along the center because I won't really be looking at it from the same angle, probably from the side.
Where did you source that amazing lil saw?
I made it ;-) It's from Harbor Freight, but modified.
Filament can be to expensive that's why you see problem on bottom layer with adhesion and wrong temp
I'm just in shock how things like this are cheap in other countries, here in Brazil even used and beat up is too expensive... love your videos, but this makes me angry because i know a lot of people that could do wonderful things if they had access to the tools.
Well done. But my god, I threw up a little when you said how little you paid for that sander.
