Open source Waveguides for CNC & 3D printing!

I don't see anything wrong with them. Can you post screenshots of what your slicer is showing or something to help me understand what the problem is?

Isn't the fact that it is the only model you created in millimetres rather in inches like other models?

I will have a screenshot to show what I see when import model to printer software

Use a professional SLA printing service and the results will be pleasing. I like JLC PCB, there are others. However it would be nice is the files were in the universal standard metric of millimetres

I save it as mm for you below.

A quick example of the price, not too bad IMO.

I don’t mind paying. Sanding and polishing and painting and finishing is not really thing when we’re having monsoonal weather again.

100mm of rain in 24 hours.

100mm... must be a southerner. 😁

JLCPCB is really affordable. Last year I inquired a few other places and got up to $100 per piece for SLS. Here it is half price. And SLA is even cheaper. The cost is really very reasonable esp given resin is not cheap.

Great find.

Uploading the STEP files will give the correct unit/scaling, and also looks like it will bypass going through the wiremesh representation of the STL files.

I didn't realise they accepted STEP.

Lucky me the place where I work for we do have 3d printers and SLA resin

You can easily see two models ps and no ps
One has visible lines which were printed. The other one is perfectly smooth and prints smooth.

Both of those files were generated at the same time, so I'm not sure why there would be a difference. And my printer didn't do anything strange with the ps version. I think your slicer is doing something odd. Do you have pics of the prints? If you unselect the non-ps version so they are both grey do you still only see lines on one?

Probably program in which you opened STEP file has changed the resolution of surfaces (triangles size). At this moment I'm preparing 3D waveguide model for CNC routing in AutoCAD and you can see how coarse or smooth surface can be. AutoCAD has FACETRES variable to define resolution, probably your printig program also has something similar.

If I would do this rough model it would have visible triangles in reality...

Yes they persists.

One saved in Inches (no ps) and one in mm (ps)

 

[Tenson]

So how about the one I converted to mm for you?

 

[augerpro]

One saved in Inches (no ps) and one in mm (ps)

They were both generated at the same time from the same model, and both are in inches. I'll download them and look at them in my slicer, but something has gone wrong with one of your files, by the slicer or something. Looking at them in F360 just now, they look fine.

Those saved in Inches working fine. It metric version gave me this result.

 

[Tenson]

And the one I shared above?

 

[rafabro]

and both are in inches

When uploaded to 3d printer software the ps version when open as Imperial was very little. Only when open as metric had proper size.
When I just opened those files in freeCAD I see them normal way. Same size and both smooth.

On Monday I can try your new links again.
