It depends on the material choice and thread size, but it is definitely possible. We have seen the best results with materials that are both very tough and very stiff. Special considerations also have to be made in the 3D printing process to make sure that there are enough "shells" or walls in the part to allow for the removal of material to form the thread. I use Alibre - specifically Alibre Atom3D. It does everything I need it to do - it was $199 - I own my license. It has STEP, part modeling, assemblies, drawings, the whole 9. The interface is simple, but it is still powerful. I imagine 99% of what most "hobby" people do can easily be done in that software. I'm a fusion360 user, mostly for simple 3d printed things. I had already stopped recommended it to people last year when they started messing with the hobby/startup license. The critical thing is that Fusion 360. Similar tools use a non-destructive parametric workflow.
Our high-resolution 3D printers provided us with well-fitted threads which smoothly work. Create an object with an internal or external thread with the Thread function in Inventor. Select the threadModeler function from the coolOrange ribbon. Select the thread you created in the Control dialog . Select the thread template (ISO/BSW) and confirm with OK. A real 3D model of the thread with the given parameters will be modelled. Another method of securing 3D printed components together is to embed a nut into the component via a nut shaped cavity . This method does not require any material removal. Often determining the optimal nut boss dimensions requires several iterations. Printing small test parts to determine the ideal dimensions can save on time and material costs. To get started, select the coil tool by clicking the create drop-down arrow in the main menu. Looking up from the bottom, select the bottom of the bolt head in the centre/origin point, then left-click and drag out the tool so that it has a diameter of 30mm. With the general shape of the bolt created, we now need to create the nut. Press β€˜C’ on your keyboard to once again, and create a 30mm diameter circle to the right of the bolt. Press β€˜D’ on your keyboard to use the dimension tool, in order to make the origin of that circle 35mm from the centre of the bolt along the X axis. 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.
