Rapid-Prototyping at memetis

Whether milling, laser or 3D printing - we are your competent partner for the fast production of small components.

We offer a wide range of manufacturing equipment, which we use for the production of miniature components. Our know-how lies in precise and fast production and careful selection of materials.

We offer the following rapid-prototyping techniques:

  • Machining (milling, drilling)
  • Laser welding
  • Laser cutting
  • Surface engraving of metals and polymers (also Inscriptions)
  • Tensile tests on smallest samples (optional additional sensor signal)
  • Reflow soldering
  • Measurements in the temperature chamber
  • 3D printing (SLA and FDM)

Machining


Due to our many years of experience in the field of milling, we can produce prototypes up to small series for you. On two different CNC milling machines with tool change, mainly polymer semi-finished products but also soft metals can be processed. Our core competence lies in the production of small structures/ dimensions (< 15 cm) with an accuracy of up to 5/100 mm. The choice of material is made with care according to your requirements and is not limited to polymers, just ask us.

Material selection from:

  • Polymethylmetacrylat (PMMA)
  • Polycarbonat (PC)
  • Polyetheretherketon (PEEK)
  • Polytetrafluorethylen (Teflon)
  • Polyamid 66 (PA66, Nylon)
  • Fiber-reinforced materials (FR4)
  • Polysulfon (PSU)
  • Polyoxymehylen (POM)
  • Polyphenylensulfid (PPS)
  • Cycloolefin-Copolymere (COC)

Laser welding of polymers

Laser transmission welding is used for the material-to-material bond between two components. In principle, we are able to bond all amorphous thermoplastics with a similar glass transition temperature. The two joining partners can be machined beforehand (e.g. channels and holes), but must be in a flat form. A special feature is the welding of transparent joining partners with a special absorption-increasing layer that is degraded during the laser process. The decisive advantage here is a mechanically stable and optically transparent connection without the use of additional material.

Welding of transparent polymers

Using a special laser welding process, transparent polymer plates with channel structures and through-holes can be welded.

Laser engraving and marking

Whether signs made of PMMA or metal, the engraving is precise and made according to your requirements.

Laser cutting

Our expertise includes the structuring of metal sheets up to a thickness of 0.5 mm but also the cutting of polymer plates.

3D printing

We print your components with our 3D printers! The costs are based on the pre-processing of the parts (STL file import, positioning of the support structures, setting of the print parameters and slice engine) and the printing time and weight. As printers we have a FDM (Fused Deposition Modelling) and a STL (Stereolithograph) available. We are looking forward to your print order.


Mechanical characterization

With our universal testing machine, we can measure force-displacement characteristics up to 100 N with an accuracy of 0.02 N. A special feature of our machine is that additional measuring signals can be coupled in for control via an AD converter. This enables us to carry out a wide range of measurements in the predominantly precision mechanics sector.

Reflow soldering

We use reflow soldering for the assembly of small series with electrical components. In this connection we structure the PCB, laser the corresponding masks from a thin sheet metal, rake the solder paste onto the PCB and finally solder. Do you need a populated PCB quickly? No problem - contact us.

Temperature chamber

We have a temperature chamber in-house with which we can carry out various tests up to a maximum temperature of 100°C and an accuracy of +/- 1°C. For example, a thermal resistance change of conductors or the temperature-dependent pressure in cavities can be measured.

Design and construction of electrical circuits

If you need simple electrical circuits, we can implement your requirements. Together with one of our experts, your specifications can be discussed so that we can design the layout accordingly. We will then take care of the layout, the assembly of the board and a corresponding qualification. The circuit boards are milled in-house.
