Rumored Buzz On How To Draw Threads In Fusion 360 Exposed

The Idiot's Guide To How To Draw Threads In Fusion 360 ExplainedIn my experience, tapping a plain hole in a 3D print runs the risk of delaminating the print. Fusion360 offers the option of just showing a thread form in a drawing/model or actually modelling it in the file. It is a simple check box in the thread dialog box. If the cone angle is not constant, you'll have to model your own thread type. You'll need to do a sweep cut of the profile along a path. Therefore, one of the things you can do with your 3D printed threads is to add a fillet or nice round over to the edge of the threads. There are so many factors in play between 3D printers being different, setting up the file in slicing software, and so on. Just keep in mind that as threads get smaller they’ll lose some of the finer details, and their clearance may need to be tweaked even more. This first thread and nut, is going to be our first clearance test. Depending on the size of the thread and the tolerance of your 3D printer, this default clearance typical needs modifications…but we’ll use it as the start of our test. The next step would be for us to apply the internal thread to the nut. To do this we can activate the thread feature. Simply select the inside cylinder. I’m going to use the circumscribed polygon to create the hex nut. From the center origin, I’ll type out a radius of 12mm. You can also clear out the command with the escape key, select the horizontal constraint in the toolbar, and select an edge. This will make sure the sketch is fully-constrained. Lastly, is the ability to check the β€œremembered size” which will remember all of these thread settings for the next thread feature you create. Because I’m going to copy this first component, I’m not going to worry about checking this option.

We’re going to create three different test threads so that you can print them out to see which clearance works best for your printer. Be sure to stick around until the very end where I’ll demo the final 3D prints. I recommend this great starter set for 3D Printed thread projects. The β€œABN Metric and SAE Standard Tap and Die 60-Piece Rethread Set” is affordable and comes with a nice hardshell case to keep the set organized and protected. If you’re wanting to 3D print the threads then you’ll need to check the β€œModeled” checkbox at the top of the Thread dialog. Having cosmetic threads also improves Fusion 360 performance when you’re using hundreds of screws or parts with threads. For example, a thread designated as m12x1 - 5g6g indicated the thread has a nominal diameter of 12mm and a pitch of 1mm. The 5g indicated the tolerance class for the pitch diameter. The 6g is the tolerance class for the major diameter. You might be able to model threads using a transverse sketch of the thread geometry. Making it follow a spiral of the appropriate pitch. For #5 nibs I just use a fine thread 1/4" thread. Close enough for me. We’re going to create a profile and sweep it along a helical path. Start the next method with a sketch on the XZ plane containing 3 concentric circles. These are dimensioned to the diameter of each section.
