Kersten Revalidatietechniek

Orthopedics and Prosthetics

A few years ago, Kersten Revalidatietechniek, a Dutch manufacturer of customized products for the disabled decided to expand its business. Kersten was already making high-quality products which allowed persons with limited physical abilities to enjoy life to the fullest. For example, the company was famous for customizing automobiles to give the disabled the autonomy a car can provide.

To expand its product line, the company wanted to begin manufacturing custom mattresses for the disabled: both for the wheelchair and the bed. After doing preliminary research on available technology and designing a manufacturing process, the company chose to purchase an Artec L scanner and started work.

  • A patient arrives at the Kersten facility or a staff member goes to the patient’s home.
  • A special vacuum mattress is used.
  • A patient lays or sits on this mattress and the air is sucked out. This leaves the mattress in the shape of the individual’s back.
  • The mattress is then scanned using an Artec L scanner and the 3D model is imported into VX software (developed by ZW3D). Scanning takes less than 5 minutes and total post-processing time is around 20 minutes for each bed mattress or 10 minutes for a seat mattress.
  • In the software, the scanned file is made into a proper CAD file and is ready to be milled.
  • The CAD model is imported into Eureka software which is used to automatically create a sensible path for the milling machine.
  • The model is then milled by a Motoman robot (model - Es165N).
  • To mill a customized mattress takes approximately 1.5 hours.

During our visit to the facility, Leon Schroen, Kersten’s workshop manager told Artec that the company is very happy with its Artec L scanner and the only request they have for improvement is to add a Start/Stop button on the scanner. This will make it easier to use. We, at Artec, always appreciate user feedback and will work toward making all of our scanners ergonomically perfect.
