From the Workshop

The nozzle diameter determines the thinnest wall and the smallest detail you can print in FDM. We explain how to manage this limitation in your design.

We explain the design logic for splitting large models that don't fit the print bed into parts, then joining them solidly with dowels and interlocking surfaces.

We share the angle and orientation rules for achieving clean inner surfaces on conical holes and funnels without using any supports.

Rounded corner or beveled edge? We explain how to choose between fillet and chamfer based on structural strength and printability.

If your parts don't fit together or spin loosely, the problem may not be in the design — it could be your printer's actual tolerance. We explain how to measure it with a single test cube.

Parts that move without any assembly or screws are possible. In print-in-place design, the secret to joints that work without fusing lies in the right clearance gap.

A great 3D print starts at the design table, not in the slicer. Here are seven practical rules for making your Fusion 360 model truly print-ready.

Everything you need to know about tolerance, layer orientation, and thread profile to design a threaded cap and bottle that fit together seamlessly.

Realistic steps for reproducing a broken home-appliance knob via 3D printing when the manufacturer no longer supplies the part.

Ways to reproduce missing or broken IKEA plastic fittings through 3D printing — without throwing out the entire piece of furniture.
