We enable you to bring your ideas to life with the help of 3D printing. Check out the 3 steps below for ordering your 3D print.



  1. There is nothing we cannot print! If your model or material needs are not compatible with the requirements below, please contact us for custom service and quoting.
  2. Make sure the model that you upload for pricing is supported: we accept .STL, .OBJ. If your design is not in one of these formats, please contact us over email for support – we support wide range of CAD and native formats, however this requires sending them directly to us.
  3. Your 3D model should not exceed 50 MB is file size. Try to optimize the polygon count or reduce it using one of the free licence software solutions.
  4. Your 3D model has to be closed and manifold. Check that our model has correct normals. Some basic holes will be automatically closed during upload.
  5. Our largest printer supports models in size up to 406 x 355 x 406 mm. Please check whether your parts fit within these dimensions, if not you might incur higher cost of printing or alternatively you will need to divide the model in several parts. Contact us for more advice how to do this.
  6. Check if your model follows the design guide lines below.


Below you will find some design guidelines for preparing a better 3D model for printing.

  1. Wall Thickness. The minimum wall thickness should be no less than 1mm. Even though we can do thinner walls, most of the prints with thinner walls pose the risk of braking in post processing. 1mm walls will always give you a strong and durable result.
  2. Details and Accuracy. The minimum suggested detail is 0.3 mm. Especially with letters that are embossed or engraved on the surface of the part, note that the minimum thickness of the lines should be 1mm; engraving depth no less than 0.3mm and embossed height of no less than 0.5mm. Accuracy of the printed part will always stay within +/- 0.1% for the whole part, but depending on technology it is mostly no more than 0.1mm on the parts that fit in our printers.
  3. Build Size, Layer Height & Support Structures.
    FDM technology will allow you to print as big as 406 x 355 x 406 mm, with layers from 0.127mm to 0.330 mm. Support structures are soluble, hence there are almost no geometric limitations. Keep in mind that FDM can produce parts with different density allowing for almost completely hollow parts.
    PolyJet printers have the maximum size of 340 × 340 × 200 mm. Layers are either 0.016 or 0.032mm and support is soluble which allows for really complicated geometries.
    SLA has the maximum dimensions of 144 × 81 × 200 mm. The layer height can be as low as 0.001mm with the minimum of 1 micron increments. Incredible detail achievable, but because of breakaway support structures you have to plan your design carefully to preserve those details. Printing times can be very long, however almost anything that we said above about the wall thickness and details do not apply here.
