@Jose Pablo Quesada I emailed you my CAD file too but if Erik can provide his, that's even better. @SS0317 seems to work okay with PLA on initial testing, but haven't gone further as we are recommending PETG. With PETG, the stacking completely fails. Either too well bonded or not well enough.

@redheadmaker I stacked a slightly different job that I'm doing right now in the same way and printed 5-high overnight. Separately fairly well with PLA, although print quality decreased and if I were to repeat, I would run the job slower. I just joined @Petko Ganachev's Slack group based in BC and will continue any work there. @Jose Pablo Quesada I have a CAD file I reverse-engineered from the STL. Do you run this injection molding facility/would you be making the negative yourself? Apologies about the weird formatting of my post. I'm no longer able to post on the website and have to email in my replies (no idea why) and the formatting is horrendous.

That's disappointing! I modeled it same as the Prusa one but theirs might have had thinner walls. I'll see tomorrow if mine worked. Otherwise I guess it's incentive to add a second extruder and use HIPS or PVA...

PETG is extremely sticky so I'm not surprised. I imagine it would work much better with PLA. I'm going to try stacking a different model in a similar way tonight. https://www.dropbox.com/s/2bs03fsnyw0r17a/Visor_Frame_NORTH_AMERICA_LETTER_v3.3-stack10-prusa.2.stl

@Petko Ganachev Can you try this file? https://www.dropbox.com/s/73a3gj07kurl9il/Visor_Frame_NORTH_AMERICA_LETTER_v3.3-stack10prusa.stl?dl=0 I modeled the separation based on the Prusa RC3 stacked file you linked. Shouldn't need to enable supports for this. I did have to add some supporting cylinders in the forehead part of the model to support the next print. May end up actually being faster to make the entire forehead piece solid and hollow it out when slicing.

Which Prusa stack are you referring to? The only stack I found in the documents section was for the Stratasys.
Commented on Protective Visor by 3DVerkstan about 1 year ago
The empty layer is likely because the way the template I followed (Swedish/Stratasys file) connected each model to the others was using a narrow 0.2 mm rod going through all the models. Would be interesting if Slicer/PrusaSlicer has the same error with that file. This is likely unprintable for most printers hence the error with the slicing software finding an empty layer. I assume you would use support material between the layers though? I can redo it using a wider diameter rod if that would help. To be honest, I'm unlikely to use these stacked models myself in the near future but I don't mind doing the CAD work if needed.

Do you have supports enabled? It slices fine using Cura.

My printer is currently occupied by another PPE project so I haven't tested the stack. I made it based on the Swedish/Stratasys printer version, but using my chamfered model instead of the original v.3 provided here.

I didn't feel like waiting for the CAD models so I did it myself. Here's the link to my version of the NA files. Chamfered on both sides, and stacked x10, x20 and x30. https://www.dropbox.com/sh/6qh0cvpbu5b9mfu/AADShdUqClApT7OgUqlturyca?dl=0

This is great! Our prototyping lab has been printing various designs and seeing what would be most feasible. I like this one due to how fast it is to print and requiring only two parts. Any chance the CAD file would be available? I notice at least on the North America version that it is chamfered on one side only. If I had the CAD file I could easily chamfer the other, and also help make stacked versions if needed. I can reverse-engineer the file using the STL, but it's unnecessarily complex....
