How to Minimize Angle Supports for 3D Printing

Since it is still impossible to cut the production of 3D products that use angle supports or frames, there is always another way to avoid it. If you want to minimize the use of angle supports, the easiest way to remember the solution is by taking note of these rules below.

 

YHT Rule

The YHT rule implies that the best way to get rid of angle supports on 3D designs is by using shapes. Keep reading because here’s how the basic YHT rule goes:

A.     Y Shape

All 3D designs that have the shape of “Y” can be printed safely without angle supports. Thus, you don’t have to worry about drooping corners since its shape creates a gradual slope. Its material underneath is also enough to support its upper part. Take note that the more gradual slope you make, the better 3D printing result you can have because it is normally safe.

B.     H Shape

All designs with the “H” shape and contain an overhanging middle part that connects both sides is also known as “bridging”. Normally, materials that have 36mm bridges contain 0 to 0.5mm drooping. Bridges that lengthen from 36 to 60mm long prints have 0.5 to 2mm drooping while those bridges that are beyond 60mm long prints have significant 2 to 5mm drooping. The materials used in printing vary so this H shape rule for 3D printing settings can be altered all the time.

C.      T Shape

Among the 3 shapes, all designs that have a “T” shape can stand on its own without angle support. Most importantly, it is less prone to encountering printing errors and damages. This is due to the fact that there’s not enough material that needed too much supports.

 

Split Multiple Parts

If you are struggling with revolving your designs under YHT rule, you can split up your design in different parts to print them easier. Once your designs are printed without too much support or none at all, you just have to link them together. To link all parts together, you can use a solvent or adhesive like super glue or cyanoacrylate. This works best for all large and complex designs.

Model Orientation

Have you ever tried rotating your models? Another way to minimize the use of angle supports is by changing the orientation of your model for printing. Take a design with a T shape for instance, instead of printing it standing; you can print it while it’s flat on its back. This way, you wouldn’t have to modify your designs all the time.

Anchored Print

By anchoring some parts of your design to its other parts, you can minimize supports on overhanging parts that would be printed. This would also allow you to print your entire design without a hanging part which normally causes printing errors.
