Some 3D Print Model Tips

Having known some of the best free and paid CAD software, let’s explore some of the helpful tips that can help you create 3D print models that are visually pleasing and functional.

Check Bridging:

The first important tip on our list is to check Bridging. If you don’t know what this is, bridging is when a 3D printer needs to print a layer between two points without any support beneath it. A good building allows your 3D print looks exactly like the version in the slicer, ensuring there are no loose strands of filament to clip off after the print is complete.

Avoid Overhangs:

Overhangs are when the printer has to print at an angle greater than 45 degrees from the horizontal. They are shapes that usually extend outward, having no direct support, ade they can cause the filament to droop or sag, ruining the quality of the 3D print.

To avoid overhangs, it’s advisable to design your model to have gentle slopes and angles that don’t exceed the recommended max angle.

Watch out for Corners:

Having rough or sharp corners, which can cause stringings, blobs, or other problems in 3D prints can be very frustrating, as they usually require lots of filament to be laid in small areas. For this reason, it’s recommended you use fillets where it’s necessary and round off sharp corners if possible.

Examine the Round surfaces:

Curved surfaces can be difficult to print, particularly if they have a small radius. Make sure your model has the proper support structure and that the printer is calibrated correctly to avoid under or over-extrusion.

Pay attention to Holes:

Holes in 3D models are usually due to over-extrusion or under-extrusion, and this can cause issues during printing, especially if they’re very tiny. With this in mind, you must always ensure to inspect your 3D model and verify that the holes are in the accurate size and shape and that no obstructions could cause the printer to jam.

One of the best ways to do this is to check the flow rate, and when changing values, start with small adjustments followed by a test print after each change.

Attach more importance to the first layers:

The first layers are the foundation of any 3D print which every other layer is built on. So, it’s critical you pay attention to the bed surface and material compatibility as they both play a vital role in the output of the first layer.

For instance, if the first layer of a 3D model is high off the bed, the output of the 3D print might end up suffering from wrapping.

Prioritize layer orientation:

Layer orientation is another essential thing to consider when printing a 3D model.

As we all know, the force of adhesion between layers is always less than that between lines in the same layer. So, when designing a 3D model, you must always consider the forces each layer will experience, as different orientations usually cause different amounts of stress on the layers, which affects the quality of the 3D print.

It’s advisable to orient each layer in a way that the force acts on them perpendicularly – this will prevent the force from separating the layers.

Final Thought

Overall, creating a 3D print model requires careful planning, design, and execution. If you don’t how to design a 3D print model, the article above has explained helpful tips that can help you simplify the process. Plus, it covers the most reliable free and paid CAD software you can use for your 3D model design, it doesn’t matter whether you’re a newbie or not.
