Steps of an SLM project


In order to study the project, we need all the possible information about the piece that you need to redesign and/or manufacture.

First, we receive the CAD model of the part, preferably in .step or .stl format .

If, in addition, we can see the whole assembly, we will better understand its functionality and we can  propose some improvements to the part.

SLM technology achieves an average dimensional tolerance of +/- 0.2 mm and roughness between 6 and 10 Ra. If the piece has more restrictive dimensions, we need a drawing with these indications. These dimensions are achieved through post-processes (machining, polishing, etc.).


The process key factors are:


- Visible faces of the piece (where better aesthetic roughness is needed).


- Manufacturing material (Aluminum or Steel).


- Quantity of pieces or minimum batch of the project.


- Finishing required.


When preparing the model for manufacturing, we offer different design possibilities according to need:

A) Direct manufacturing of the received model.

B) Make small modifications to improve the manufacturing of the part:

C) Design from scratch to optimize additive manufacturing, reduce cost and improve functionality:

Once the final design is obtained, the parts are positioned on the machine using the corresponding software.

The orientation of the part during manufacturing defines the post-processes and the final cost of the part.


Depending on this, the support structures will be placed in the necessary areas.

The pieces are distributed on the plate  and the optimal parameters for the chosen material are chosen. In this way, manufacturing data (time, volume, etc.) are obtained.

Once the manufacturing is finished, the pieces of the plate are separated and the supports are removed.

Finally, a blasting process is carried out to clean the part and improve its roughness.

Depending on the dimensional, functional or aesthetic needs of the piece, it is possible to carry out different post-processes.

To achieve the most restrictive tolerances it is necessary to carry out a machining operation .

To improve roughness, different polishing processes are carried out: manual, vibrated or electropolished.

It is possible to carry out different treatments to achieve aesthetic finishes: painted, chrome, etc.

After carrying out the corresponding quality controls , the pieces are sent to the customer.
