We have a bouquet of machines in the Fab Lab that use different manufacturing processes. Here you will find an overview of which machines we have and what features they have. You can find instructions for use and tips under Machine operation.

Additive Manufacturing

FLM (Fused Layer Modeling)

Fused Layer Modeling (FLM) or Fused Deposition Modeling (FDM®) is probably the most accessible 3D printing process. The printing material (filament) is fed by an extruder motor into a nozzle, which has previously been preheated to the special melting temperature of the particular material. This nozzle melts the filamentary material and deposits it on the usually heated print bed by moving the print bed (build plate) and the print head. Through repetition of this process the model grows layer per layer.

By repeating this process, the model grows layer by layer. This allows objects to be printed that are intended to be similarly robust or more robust than aluminum, for example.

Advantages: Low pre- and post-processing effort. It is possible to insert additional components into the model to be printed during the printing process.

Disadvantages: Comparatively poor surface properties.

Stereolithography (SL) or (SLA) is an additive manufacturing process in which a photopolymer resin is used as the printing medium. This synthetic resin is cured during the printing process using a laser beam that is guided over the print bed based on the model to be printed. This process is repeated layer by layer. The model must then be freed of excess resin in an alcohol bath and finally cured in a UV bath.

Advantages: This process offers the highest precision and the best surface properties.

Disadvantages: Large pre- and post-processing effort, furthermore caution is required when working with the synthetic resin as it has toxic properties.

LS (Laser Sintering)

Laser sintering (LS) or selective laser sintering (SLS) is similar to stereolithography (SL) in that a laser source is used to cure the material. In this process, however, a powder is used instead of the synthetic resin, which is then cured on the basis of the specified model. For this purpose, fresh powder is pushed over the already cured areas in layers and then cured again. The previous powder layer thus supports the model or the next layer during production. This process is repeated layer by layer.

Advantages: The LS process offers excellent precision and surface properties. In addition, even complicated shapes can be produced without support structures.
Disadvantage: Large amount of preparation and follow-up work.

Collaborative Robot Arm

The UR10e robot arm is a collaborative robot equipped with a gripper and quick-change system. The arm can be used to perform a wide variety of tasks that require high precision. Work steps can be programmed and taught and thus automated. In the future, the arm will be converted into a 3D printer that will make large 3D models a reality.
