Anything in a “Y” shape is safe to print without support because it’s a gradual slope which still has enough material beneath it to keep it from drooping.Thanks to one of our top designers who wrote a more detailed article on Supports and the YHT Rule. This is a good way to remember what shapes are safe to design without supports and which to avoid. If you can’t avoid using supports but do have access to a dual extrusion printer, we recommend using a soluble supporting material like HIPS, which is discussed in more detail in our filament guide. The picture below is an example of a 3D printed part that is printed without supports (left) and with (right). In some cases, the surface may be damaged beyond reasonable repair when using supports. Keep it simple to raise your chances for a successful print!Ĭreates smoother surface finish: Using supports typically creates a rougher surface and again, creates more work during post processing to smooth it out.
It’s common for longer, more complex prints to fail much more frequently than short, simple prints. Lowers probability of printing errors: Supports add more complexity to the design which raises the probability of errors when printing. When you add in the time required to clean up the supports post-print, the difference in time to completion can be significant. Additionally, adding supports means the product will take longer to print (more material = more time), and we’ve seen supports increase print time by up to 100% in extreme cases. Saves time and money: Designs that require a lot of supports waste material, since the supports are removed and likely thrown away once the print is complete. Here’s a few reasons why you should care about reducing supports: Benefits of Reducing SupportsĪlthough supports are sometimes necessary, there are a lot of benefits to designing in a way that avoids them altogether. If you’d like to ensure a specific support structure is created, you can design it into your model directly, but in most cases, the auto-generated support structures do the trick.

In most cases, the supports are automatically generated by the slicing software that converts your STL file into a format the 3D printer can read, called G-code. After the print is complete, the supports can be broken off and cleaned up to leave you with your final design. Depending on your design, supports may be necessary to prevent filament from drooping when it’s printed. Supports are extra material that act as “scaffolding” to hold a design in place if there is nothing beneath it to build on. Design To Avoid Supports What are supports? To create an easily printable object, there are five key design rules to keep in mind: 1. Something that looks beautiful in your CAD program could be extremely difficult or messy to print which creates a frustrating experience for any Maker. Solidworks.Designing for 3D printing can be quite different than designing for other purposes. TinkerCAD is a web-based 3D modeling and designing tool. What is the Best 3D Printing Software?
