SLS creates a new potential for design in medical technology
Laser sintering technology enables medical technology designers to print plastic objects for feasibility studies within a very short time. The functional prototypes largely have the same properties as injection-moulded parts. EEM AG goes one step further: It manages a balancing act between the production of prototypes and small series.
‘The spine is the key to health’ – Cyrill Aemisegger, responsible for development, technology and production at EEM AG, reminds us of this 2000-year old quote by Hippocrates: ‘That’s where we start.’ The young company manufactures various health-promoting products under the ‘grow concept’ brand that enhance well-being and performance at home, in therapy or at work. In addition to a sound system with soothing music and relaxing, scented aromas, EEM’s flagship is its developed and patented special chair, which – using an innovative process – relaxes the back within 10 to 20 minutes.

More than 20 printed parts per chair
FFF and SLA did not meet the requirements
Exemplary essence of SLS
Selective laser sintering offers designers and engineers fascinating ‘process-specific’ possibilities that allow for completely new designs. An example of this is the quick-release system of the headrest, which impresses with its small but subtle ingenuity: The design of the two moveable parts printed inside each other would not be possible with either a conventional manufacturing system or any other affordable 3D printing system. The advantage of this design: With the mounted spring, the locking function is also elegantly provided. ‘Thanks to SLS technology, we can implement more complex designs and build them precisely for their function,’ continues Cyrill Aemisegger.
The use of the Sintratec S1 has had a significant impact on EEM’s engineering. ‘Since using the Sintratec S1, we have been designing in a much more function-oriented way’ sums up Cyrill Aemisegger. ‘The Sintratec S1 is used day and night in our production and it is hard to imagine working without it.’
