Order Notes:

  • If you want a different number of layers for the lower and upper parts of the object, please indicate this in the order notes.
  • If you have a discount code, you can apply the discount at check-out.
  • The accuracy of our printers is 0.1 mm.

Order support:

Upload data:
3D models are accepted in stl, obj, stp, step, igs, iges file format, with a maximum file size of 50 MB.
– Simple image files (such as “JPG” or “PNG”) cannot be uploaded as they are not three-dimensional objects.
TIP: Save/export your models for upload preferably as an STL file with the unit of measure “mm”.

Materials:
In this link you can find a complete guide on which material is the most suitable for your requirements

  • Note that for flexible materials like TPU and PP the print supports leave significant marks on the object and therefore We do not recommend including designs that require print supports in the case of flexible materials, we are not responsible for imperfections in the finish, in case of doubt, do not hesitate to contact us before placing the order.

Our 3D printers offer the following print volume: 220 x 220 x 250mm (length x width x height)
– For larger items please contact us
– The tolerance range of printed parts is usually +/- 0.1 mm.
– By default we use a 0.40 mm diameter nozzle.
(The use of 0.25mm; 0.60mm or 0.80mm nozzles is possible, please leave us a note when placing your order with the desired print nozzle size).

Choosing the proper layer height:

Your model will be broken down into many individual layers for processing by our 3D printing (FDM) process.
The height of the individual layers determines the subsequent "resolution" or fineness/precision of your 3D print.
Therefore: "The lower the individual layer height, the finer or more complex the object is printed."
However, the following must be taken into account:

  • Halving the layer height inevitably doubles the print time.
  • The trade-off between the desired quality, the printing time and the resulting printing costs must therefore be thought through individually, because:
  • Not all geometries necessarily require a low layer height to appear high quality. (Curves or inclined planes require a significantly lower layer height than straight wall lines (such as in a cubic box) for clear viewing.)

In the following comparison, you can see what effects different layer heights have on your object:

Model supports:

Depending on the shape of the object, some support may be needed while printing, this could cause some marks on the printed object where the support rests (even after removing the supports), Due to this, we are not responsible for the possible marks that the support may leave on the object and we will not accept returns for said reason..

Therefore, it is always better for designs to require as little support as possible.

 

 

Choosing the right fill density:

You can use the fill density to determine the stability (or weight) of your object. Please note that infill uses a lot of material and will increase the price of the print.

Our advice is to check the price difference by selecting different fillings and thus have an orientation.

TIP: “A filler of 15-20% is completely sufficient in most cases (due to a stable grid structure)”
10-30%: For models that are used for illustration or dimensional tests
30-60%: For models that are going to be exposed to a certain mechanical load – Eg: functional tests
60-100%: For models that are permanently exposed to mechanical stress – Eg: use in industry, stress tests, etc.

  2. Javier

    Very good price, pretty good result, thanks rj enginnering team

  3. rober (verified owner)

    I ordered some designs to print and the rj engineering team helped me improve it to obtain a better result, the order took a little longer but I am happy with the result

  4. Fred

    fast service and good quality, ill buy again 🙂
