Thanks for the suggestion. It is about 45m wide and high. I think if I can get away with not needing to clean up supports I would prefer it. It is still able to be modified in Freecad so re-doing it in two parts as shown either side of the red line in the previous post, looks like a viable option to...

Another approach may be to form in two parts separated as shown below. I would delete the small radii. The narrow part would be fragile to remove from the plate, and the outer edge would be as rough as the build plate. But it could be manually smoothed and rounded. I think I'd fit the two parts toge...

Further to my above, here is the full shape and cross section. image2797.png The only way to avoid the fine flange from being broken seems to be to cut the model into 8 parts: diagonally and vertical and horizontal, and build so each piece hangs perpendicular, starting the build at the mid-frame cro...

Sorry I can't see the image. Hmmm. It shows for me. Here is a link https://1drv.ms/i/s!ArugkEfpRQyChN4SRj3QIg8RarjOBw?e=w38wnw But, I think I see my original question was misguided. I was thinking of the relative sectional areas overall, but the important factor is the angle of any overhang. In my ...

The overhang on my part is difficult to visualise on the whole part but I've cut it in half so you can see the cross section with the little overhang. http://www.3dprintingforum.us/download/file.php?mode=view&id=3929 Actually I will try the whole part, with the starting plane the flat bottom. Bu...

Sometimes a model has a narrower section whose strength must be enough not to break in reaction to the sticking force at the build face. Is there a rule-of-thumb ratio? For example I am drafting a shape where the cross section area of the built resin will be 50% of the area "above" it, and...

OK, I've had a look at the files, as I'm no expert on Freecad I can only make my observations. One of the faces has more details in it the the other, see the face with one if the facets highlighted in green: LH-wing.png Lez I think the difference in level of detail is the small file has flat-sided ...

I'm not familiar with that program but maybe others are. Can you detail how you exported them, step my step and any options you chose? As I said in my edit, there may be no problem, as both sliced into similar sized files. For exporting, I selected all the 'bodies' (one for the main block, plus one...

I have made two models in FreeCAD, both by similar processes. Left and right sides of model helicopter wire cutters. Both file sizes similar around 180 KB. (But the "RH dome heads" one takes ages to open). I exported both the the slicer software Anycubic photon workshop, which seem success...

There seems to be lots of on-line advice on reducing sticking to the FEP film, and to avoid the model separating from the build plate, but there must also be a danger of the model breaking in the middle if it is too skinny (small in cross section) comparted to the FEP contact area which resists lift...

That blemish does not appear in my slicer software. Anyway, although I think I saw a recommendation that step format was the best export format for 3D printers, and there is probably a way to control the level of detail, it seems that .stl export for me gives a fine result. So far I have not actuall...

OK here is the freeCAD file and the exported .stl and stp files

When I exported from FreeCAD into an .stl (as opposed to .stp) file, the imaging in the slicing software showed smooth, unlike the faceted image from the step file. Also the .stl file is 35 MB compared 0.15 MB, which is a giveaway that it is carrying finer resolution.

Attachment of .step or .stp files seems to be not permitted.

I'm designing in freeCAD and exporting as step files to Anycubic photon Workshop slicer. On small cylindrical parts (about 10 mm diameter) there are visible facets. I tried altering the resolution for export in the CAD software and so far am only viewing the 3D images in the slicer software, but wha...
