Adding Screw Threads To 3d Printed Parts New VideoThe issue isn't paying, it's how much you have to pay to get in. I guess they are lucky that people can't just do what they did with Photoshop in the 90s; yay for the cloud. How many people are really able to spend that kind of money on Fusion 360? Fair enough if you are one of the lucky few with thousands of pounds worth of CNC equipment in your garage. This issue with Fusion seems like it might be a good opportunity for Solvespace to get more attention. I know I've looked at Solvespace in the past, but it has always seemed stagnant, what with the website saying the last release was in 2016. Since it seems like it is still under development, it might be a good time to do a v2.3.1 release and update the downloads page, along with a note that v3.0 is "coming soon". In my opinion, out of all of the CAD you listed, Solvespace is by far the best to teach someone starting out. The interface is not absolutely overwhelming unlike every other option, it is super fast and lightweight so you don't get frustrated, unlike every other option, and it is pretty amazingly reliable. Rhino also has Grasshopper for parametric/programmable design. The visual code aspect can be a little tedious though. If you don't mind pending a bit of $, and need something parametric, then Alibre CAD ticks a lot of the same boxes as F360. So, IMHO I _REALLY_ want an opensource solidworks/fusion360/etc competitor but at the moment its just not there yet. From the video's it looks like it should be, but once you start using it, its an endless ball of frustration. FreeCAD lets you do parametric modelling. Well as seeing all of your changes while you're making them. That’s good to know I can edit stl’s right in openscad. But wow cadquery looks like quite an improvement. I’d prefer to work in python anyway. If you're looking for an intermediate thing, check out cadquery, which uses the same geometry engine as FreeCAD but has a very OpenSCAD-like feel and language to it. OpenSCAD itself just visualizes these. Allows you to easily set parameters via a GUI.
Before continuing, I should point out that Fusion 360 does have a thread tool capable of creating a number of thread forms by simply entering measurements in a dialog box. It supports a lot of thread types and it’s definitely the way to go if you’re working with standard fasteners or if a standard thread form will do. For a model to be 3D printed complete with threads, be sure to check the modeled box. The threads will have to be fairly coarse to get reasonable results on our FDM printers. Un-modeled threads merely communicate the design intent to the manufacturing team. This saves a lot of space in the design file, allows for much faster rendering, and is appropriate when the threads will be cut by a tap or die as a secondary manufacturing step. Generally, ¼-20 or larger creates functional parts without the need for post processing. For smaller screws, the threads should be customized to create a better fastener. For example, printing a semi-circular thread profile and using a 0.1 mm offset gives better thread engagement with improved wear characteristics. For all screws, it’s best to orient parts to avoid support structures touching any threads. However, to give you the best 3D printing experience, we will show you two ways of 3D modeling threads. We will start with the automatic Thread Tool, but also show you a second option and how to customize them. Lastly, we will also showcase you how to design internal threads. All you have to do now is to Select the wall of your cylinder. Fusion 360 will adjust the settings for us since we created a circle with 10 mm in diameter. For standard thread, settings are ISO Metric profile, 10.0 mm size, Designation M10x1.5, which sets the pitch of the thread to 1.5 mm, but you can edit it if you want to go finer. You can select the class, which states the tolerance class
