Practical guides for getting manufacturable 3D models out of drawings and photos. Looking for pre-sales questions instead? See the FAQ.
Getting started
Supported file formats
18 input and 29 output format families: current availability, CAD geometry, service levels and scan guidance.
From model to manufacturing
Sending a finished part to the 3D Spark platform for quoting.
What Voluminate is built for today
An honest look at what our AI has been trained and optimised for — and what to expect from other inputs.
What works best
Technical drawings that work well
What a well-suited drawing looks like, with real examples from the app.
Photos that work well
One photo is enough — up to four, 90 degrees apart, is better.
Input types we have not focused on yet
Schematics, mechanism diagrams, electronics and everything else — what to expect if you try them.
Getting the best result: quality tips
Scale references, assemblies, quality scores and what to try when the first result is not good enough.
Conversions
Using the part brief effectively
The single biggest lever on reconstruction quality — what to tell us that the image cannot.
AI Preview, AI CAD, Engineer Checked and Engineer Built
The four services, their outputs and when to choose each one.
What the conversion statuses mean
Uploaded, converting, ready, failed — and what to do about each.
Requesting a better model
Feedback, Engineer Checked reviews and Engineer Built upgrades.
