3D analysis of your part

Upload a STEP or STL file and see at once what our engineers look at before quoting: wall thickness, undercuts, draft angles and the areas where the mould steel is left too thin. Free, in your browser, with nothing to install and no sign-up.

The viewer opens right here. Your file is analysed on our servers and deleted as soon as the calculation ends: it is not archived and nobody else sees it.

You can also open it full screen: 3D viewer. For a quote with prices and lead times, use the quoting tool above.

What it measures

These are the same measurements we use when quoting, on the same geometry engine: not a cut-down web version.

Wall thickness

A colour map on the part: where the wall is thin and where it is massive. Walls that are too thin do not fill, walls that are too thick shrink and leave sink marks.

Undercuts

The surfaces that cannot be released along the mould opening direction. Each one means a side action: one more piece of mould, and one more cost.

Draft angle

The faces below the threshold you choose. Without draft the part scores as it is ejected, and on a visible surface it shows.

Thin mould steel

The areas where, to make your part, the mould is left as a thin blade. Those are the places where a mould breaks first.

Volume and bounding box

Volume, surface area, bounding box and projected areas: the numbers a price is built on, both in 3D printing and in injection moulding.

How many fit

How many parts fit in a build volume, with the spacing you want to keep between them.

How to use it

  1. Open the viewer above and drop your file into it.
  2. Turn the part and pick the measurement you need from the top bar.
  3. If you need the price, the “Get a quote” button hands the model over to the quoting tool — no need to upload it again.

Formats and limits

The viewer opens STEP, STL, IGES, 3MF, OBJ and PLY.

For a quote we need STEP or STL: the other formats can be viewed and measured, but to price them we ask you to re-export.

A STEP file under 5 MB is tessellated by your browser; above that, our server does it, which is faster. STL files go up to 150 MB, though over the internet the practical limit is 100 MB.

What happens to your file

An STL, and a STEP under 5 MB, stay in your browser: they never reach our server at all. When a calculation of ours is needed, the file is uploaded, analysed and deleted as soon as the calculation is over. It is not archived and nobody else sees it.

If you then send the part to the quoting tool, that file is kept, because it is the model we quote on: you will find it in your account, and you can delete it whenever you want.

From drawing to price

The analysis tells you whether the part can be made and where the critical points are. The next step is the number: in the quoting tool you choose technology, material and finish, and the price updates as you change your choices — for MJF, FDM and injection moulding.

If the part is delicate, or if the analysis raised a doubt, let us look together at the same measurements you saw on screen.

The analysis is a design aid, not an inspection: the values depend on how the model was exported and tessellated. For a formal check, let’s talk.
