What do you need to know about wall thickness for 3D printing?

In order to choose the perfect wall thickness for your design, you’ll need to consider three things: the purpose of your design, your aesthetic goals, and the physical 3D printing process. Minimum wall thickness varies based on the type of 3D printer.

Which is the thinnest 3D printer for walls?

In general, SLA 3D printers can create the thinnest walls of all 3D printing technologies, but there are differences from machine to machine. For example, Formlabs’ own Form 3 SLA printer offers more design freedom than its predecessor, the Form 2, because it uses a flexible resin tank to significantly reduce peel forces during printing.

How does simplify3d allow you to print thin walls?

Simplify3D also has the ability to vary the thickness of these extrusions, allowing you to print shapes with a varying cross section. For example, if the blades of this model had tapered from 0.35 to 0.25mm, the software would have made the appropriate adjustments to achieve the tapering effect.

What happens if you print on a thin wall?

As a result, the thin wall would buckle, causing warping in the part. Even if a thin-walled part prints successfully, the fragile part still has to survive cleaning and removal of support material. Cleaning methods include water jet and picking away the residue, so many thin components break at this stage.

Thus, when turning a 3D model into a real 3D print, wall thickness is needed. Wall thickness is simply the distance between one surface of your model and its opposite sheer surface. Many printing problems can be traced back to wall thickness issues.

Why does my 3D printer Print the wrong size?

Nothing aligns, the holes are the wrong size and nothing fits. Print dimension accuracy is actually one of the few areas of 3D printing where it’s highly likely that your printer is absolutely fine. Before checking the printer for faults, double check that the dimensions of the 3D model are correct.

How big should the top layer of a 3D printer be?

So if you are printing an object using a 0.1mm layer height, you would want a top/bottom thickness of 0.6-0.8mm so that the top surface of your print can close and prevent the sagging/pillowing effect. Keep in mind though, if you have really thin layers, your print is more susceptible to warping and curling because the layers become more fragile.

How does thickness affect the strength of a print?

This defines the thickness of the side walls and is one of the biggest factors in the strength of your print. Increasing this number will create thicker walls and improve the strength of the print.
