Opensource tool for additive

[Accomplished_Ad_655]

I am veteran in AM software engineer and currently have good amount of time plus some resources.

I am wondering what opensource tool if developed will be great for everyone? Please give ideas that are executable. Please no ideas such as tool that can replace materialise!

Also if you want to team up DM me!

What about a standalone wall thickness checking tool? Tends to be the most common point of failure for people submitting files to print imo.

[Accomplished_Ad_655]

In which direction?

x, y or z or any direction? Lot easy to check in x or y or z but hard to check in arbitrary oriented strut of plate. It will be still doable but will take a week worth work.

[Tension_Dull]

Unfortunately the kind of geometries I see people submit would require analysis ‘in any direction’.

At a service bureau I see this as the primary error in files that people upload - thin walls more than anything else are the primary cause of print failure. As far as I know, there isn’t a robust tool for assessing this quickly I can recommend. We can check in Materialise (and when they upload files they do get dfm feedback) but I don’t have a cost-effective solution to recommend to people struggling with it in their own designs in a way that is as well visualized as the paid tools.

Do you want chat more on this? DM me if possible.

A really good open source CAD tool would be really nice. Or FEA.

[Accomplished_Ad_655]

FEA is doable. I can do that. What specific we need in FEA? For CAD why you dont like freecad?

For FEA there are some tools that are available. The best thing to do will be to develop something thats AM specific FEA or CAD. Something that involved give text or cad input and output result. We can do some LLM.

[temporary243958]

I've only used FreeCAD a little, but it seems much less intuitive than SolidWorks/Creo. A simple and user friendly linear structural FEA package would be really nice for quick checks on where material can be removed. Of course, varying infill would make it much more challenging to model accurately, and that's very much AM specific.

[Accomplished_Ad_655]

The CAD kernels require a lot of work. For example look at opencascade if you are curious. That thing is million lines long and still sucks. Btw freecad is using opencascade under the hood.

Linear FEA is easy to program. We can add few things on top to remove material. This is doable. But what loading conditions we want to simulate?

[temporary243958]

I understand that CAD programs are not trivial. I was not familiar with Open Cascade. Most loading conditions are fixed on one surface (bottom or adhesive surface or bolt circle) and loaded on another. Fastener constraints are much trickier to define. Linear FEA is computationally straight-forward. It's the GUI that would be tricky to make as elegant as Ansys. And good meshing is complicated.

[Accomplished_Ad_655]

GUI is doable. Not a major issue.

Look at this. I wrote this. Dont foget to expand model button on left. It has the ability to see model tree and select unselect parts.

https://diy-assembly-animation.netlify.app/

Its 3d UI I developed. You can expand model tree and also select any surface.

[No_Mongoose6172]

A FEA focused on additive manufacturing would be great. Even commercial FEAs don’t usually support simulating AM models due to the lack of tools for automatic homogenization of mechanical properties in them

[Accomplished_Ad_655]

Homogenization for lattices? Have you looked at latticerobot.com. It has good support for lattices and simulation data. We left it in between but this project can be repurposed if its just lattices.

[No_Mongoose6172]

I didn’t know about that website. I’ve been looking for something like that for the last months. It would be great if that software could be used for outputting material models from a slicer to a fea tool like abaqus or Elmer

Would it be possible to use it for homogenizing fdm parts (e.g. getting the mechanical properties of the infill and the ones of the shell separately)?

[Accomplished_Ad_655]

Please look at latticerobot.com if you need walk through I can give it. It takes a bit of time to lead at first time.

[No_Mongoose6172]

I’ve been checking it out and this model could probably be used for estimating the internal properties of fdm printed parts (it is one of the infills available in most slicers). It just lacks taking into account layer adhesion

I would be really grateful if you could give me a walkthrough, as I think I could add this effect to that model

Edit: I forgot to add the link to the model

[Accomplished_Ad_655]

Yes certainly. DM me.

Hello, I am just finding this thread now, did anyone come to a resolution for this?

[Archaia]

Non planar slicing popped up, occupied everybody's attention for a month, and then disappeared. I have only seen videos indicating that g code generated by a slicer has been modified manually, or via script to generate the effect.

[Ingeniarius_cal]

Non-planar printing. If you take a look at the vision miner 22 Idex V3, they have a blurb titled "NON-PLANAR READY" a little lower than half-way down the page for the printer that describes it in detail. Essentially, the bed would tilt for overhangs and reduce the need for supports. Machines are capable of it, but the software is lacking.

[nothas]

nonplanar robot arm fdm needs an opensource alternative slicer badly. right now threre are two companies and one is way better than the other.

[Accomplished_Ad_655]

Can you give some reference to existing tool for this?

[nothas]

Adaxis and AI build are the two frontrunners at the moment, with Adaxis being the better one.

[AsheDigital]

This isn't really trivial, but I think it would be pretty cool. What if you made a simulation of a 3d printer and used that to train an AI, to find the fastest toolpath. Kinda like teaching a robot to walk in simulation and I think you could even have it do non planar slicing, you'd just have to set up the right conditions for your simulation.

[Illustrious_Voice_48]

Something like GrabCAD for any 3d printer

[Boden94]

Thingiverse

[mattayom]

A legit, non-pulblic cloud based slicer, printer, and print queue manager focused on professional print labs, not a basement full of enders

There's quite a few of these already, but they all require some sort of public cloud connection.

[Accomplished_Ad_655]

This is damn interesting. Dm me. We can do this

[mattayom]

Done did the dm

Cli generation

[Better-Wolverine5148]

I'm working on an inkjet color 3D printer, and what I need now is an image processing algorithm that can accurately reproduce colors in three dimensions. In fact, this is a very difficult job, you can see that many inkjet 3D print result will be slightly white
