![]() With this you make an horizontal section. ![]() It allows you to check the section of a part.īefore we begin with this it is ver recommended to deactivate Incremental Move so you can move section plane without jumps.Īpply Section Analysis and select the XY plane (TOP plane). A good way to check what you are doing is to use Inspect – Section Analysis. We all want to avoid supports when we design for 3D printing. Thanks to having parameters, if you need to change of material or machine, you only need to modify the “holgura” parameter value and export to STL again to have the model adjusted to the new material or machine. And you can use it in the following operations to adjust tolerance. Once created you can modify the Press/Pull operation by replacing -0.2 mm value with “holgura” (or your preferred term). (“holgura” is the translation of clearance in Spanish, use you own term) The beauty of working with parametric software such as Fusion 360 is that you can convert this -0.2 mm value in a parameter that you can change any time, and use it in all Press/Pull operations that you have applied, or will apply.įor this we create a parameter “holgura” in Modify – Change Parameters. In a threaded hole, you have to apply the same by selecting all inner faces of the thread. In a hole, simply select the hole inner face and move it out (-0.2 mm in the example, so -0.4 mm in diameter). In Fusion 360 we have the tool Modify – Press/Pull (shortcut key ‘Q’) that allows you to offset one or several faces. In this case your option is to modify the design. But this affects the whole part and it may happen that you only want to apply this toa hole for example, or a hole in a vertical orientation that would not be affected by expansion that is only horizontal. With the slicer you can use the horizontal expansion parameter to modify the size of the part in the horizontal plane and offset for the material shrinking. Here you have an example of tolerances test. There are several models in Thingiverse that you can print to confirm what you need for a specific material and 3D printing setting. It is usually 0.1 to 0.5 mm in FFF 3D printers.įirst thing is to test the machine to know the tolerances that it has. One of the most relevant is the type of material, and ideally in these cases is to adjust the model with enough clearance in parts where there are inserts or threads. Apply clearance by parameters for 3D printer toleranceĮach 3D printer has its own tolerances in relation to many parameters. Effect of 3D printing fillets and chamfersġ.
