Large companies aren't trying to stop us printing medical equipment - they are trying to stop people from copying their designs. If we want to print some valves we should design our own valves and optimize them for 3D printing. That way we don't infringe on copyright and we should end up with better printed valves anyhow. I'm not sure whether 3D printed valves are very sanitary, though. The tiny ridges of the layers can accumulate dust and bacteria.

Are the line width of the top bottom and the walls also the same? If all that fails then the only thin I can come up with is that you might need to reduce the flow percentage. The difference eventually comes down to the fact that the print head just spend more time on those players than in the layers with infill.

Also: disable capslock?

If only 3dhubs was still open to the general public. Does anybody know of an open alternative that lets us make our printers openly available?

You say the long slice times are only when you have tree support enabled? Are you sure that tree support didn't always take a lot longer to slice?

Here's a model of an Ultimaker original: https://www.youmagine.com/designs/miniature-ultimaker-1-6 Can't find the S5 one..

It's a bug in the current way that walls work. It is kind of inherent to how walls should be generated. Walls should be generated on all sides of a print, so also both sides of your thin region. That means that across that thin region it will always generate an even number of walls. If you model a part to be exactly as wide as 3x the line width then depending on which way the rounding goes it will either fill using 4 lines or using 2 lines (and fill up the remaining space using a single line, if Fill Gaps Between Walls is enabled). We're currently working on a fix, but it is rather complex, so it might take a few months before it becomes available in Cura. Meanwhile: try adjusting your part or adjusting the wall line width or enable Fill Gaps Between Walls.

SketchUp has a lot more problems for 3D printing, though. It automatically generated faces on the inside of your 3d model, which are invisible to the user, but they confuse the hell out of the slicer. You often need to do a mesh repair of your model before sending it to the slicer. I heavily recommend against SketchUp.

If you don't want those walls you can turn off the Support Wall Line Count to zero in the settings.

Ah yes. Indeed.

Yeah. Minimizing infill can be difficult. You could look at gradual infill and infill meshes. Those are some advanced functionality to be able to control the infill better. But truth be told, it's not easy to understand. Maybe first get the hang of support blockers (*overhang* blockers).

A Cura generated gcode does contain the settings at the end of the file. You can load the settings from a gcode file by Manage Profiles > IMport > select gcode.

Support was being added for the top of the part, but the support is a bit wider than the overhang. That's meant to be able to support that top surface better, but in this case it was so far removed from the top surface that it ended up outside. You could also have prevented the support by reducing the support horizontal expansion setting. Now I just tell the program not to see the top surface as overhang at all, so no support is generated in the first place. The support blockers are actually blocking overhang, not the support structure itself.

Hmm I am coming up empty handed. I can't really find why this is happening on your printer. Sadly I don't have a CR-10, so I am unable to reproduce it on the printer. Hopefully somebody else is able to help you...

Oh you mean at the bottom? I don't normally do case-work like this, but here I am helkping you anyway. 😄 Problem situation: Adjusted settings: Support touching build plate only, minimum support area These settings didn't cut it. Solution: Remove customized settings and start fresh 🙂 Add support blocker: Select and scale the support blocker: Result: Here's the project file for you! [attached] Happy printing!

Small inset? I'm not sure what you are talking about. Could you grab a screenshot and (e.g. in MS Paint) draw a circle around the 'smal inset' you want to have supported?

I implemented the modifier mesh settings. I am fairly sure it's not possible. If you use an infill mesh (modifier mesh with Infill Only ticked) the outer wall will not be modified, but if you use a cutting mesh (modifier with Infill Only unticked) you will get a wall at the boundary between the modifier mesh and the normal mesh, so the epoxy wouldn't be able to spread. It would definitely be an interesting feature to be able to make holes in the shell. However, I'm not sure how this feature should be implemented. If you want a hole in the vertical walls you would have to interrupt the Outer Wall print lines, which are normally always closed polygons. This means that there will be a lot of interaction with other code dealing with walls and it will affect the printing as well. If you want a hole in the Top/Bottom skin it would be a lot easier to implement, but then it would be difficult as a user to configure a hole in a nearly horizontal surface, because the walls would then still be printed as bridges accross the hole.

What printer? Probably acceleration and jerk settings. The defaults might have changed in order to ensure a higher print quality.

I'd like to get to the bottom of this. Could you please share your project file? could you please share some screenshots of the layer view?

Of course. Automatic support generation is rather complex to get right. To me the minimum support area setting sounds like a workaround for some manual change you want. If those areas don't satisfy the overhang angle then you shouldn't remove those areas based on their size. Size dependent support removal means that some small details will never be supported, no matter how bad the overhang is. It's really easy to get it to block exactly where you want, because you can simply click the location.

Just click the support blocker tool (left, bottom) and click the location on the model where you don't want support. There's really not that much to get the hang of.

It's not really possible to make a hole in the shell at a specific place only at the moment.
