5Route steps
+/-0.2mmTypical tol.
A custom insole is primarily made by SLS (Powder). SLS 3D printing fuses nylon-based powder with a laser layer by layer, with the powder bed supporting the part so no supports are needed. Below is the full route to make a custom insole, the materials it suits, the tolerances to expect and the main design points. The route is free, from the finder.
Step by step
How a custom insole is made
The usual route, raw material to finished part. The amber step is where the custom insole gets its basic shape.
CAD and slicing
Prepare the 3D model, orient the custom insole and generate supports and layers.
SLS (Powder)
Build the custom insole layer by layer.
Tooling None Tolerance ±0.1 to 0.3mm Lead days
Support removal
Take the part off the plate and remove the supports.
Surface finish
Bead blast, tumble or sand to the finish you need.
Inspection
Verify dimensions and, for metal, check density and porosity.

Cost
What a custom insole should cost
Nylon powder, no supports, good functional parts and complex geometry; nests many parts per build for efficiency.
PER-PART COST vs VOLUME
Per-part cost drops as volume spreads tooling and setup over more parts. The exact figures for a custom insole at your volume, in your currency, are in the dossier.

A custom insole is primarily made by sls (powder). The route is: CAD and slicing; SLS (Powder); Support removal; Surface finish; Inspection.
What does a custom insole cost?
It depends on size, tolerance and volume. As a rough ballpark it starts around $29 to 50 per part at 1 off and falls with quantity. The dossier gives should-cost at your exact volume and currency. A model estimate, not a quote.
What material is a custom insole made from?
Common choices are Nylon PA12; Glass-filled nylon; TPU.
What is the main process for a custom insole?
SLS (Powder). Functional nylon prototypes and low-volume end-use parts with complex geometry.
