CERTIFIED SOLUTIONS FOR HEALTHCARE COMPANIES TO MEET PATIENT INDIVIDUAL REQUIREMENTS
Case Study: HKK Bionics
Patient-individual hand orthosis with integrated sensors to restore the gripping function of paralyzed hands

The final product consists of many different small parts that all need to be assembled. All those parts require a homogeneous surface treatment and consistent coloring. In the end a medical product like this must pass tests for cytotoxicity and skin irritation tests, which sets high demands to all processes involved. Since the product is worn by patients every day, it must look and feel good.
Homogeneous surfaces with pleasant haptics and matching skin colors: To produce the 3D-printed parts of the exomotion hand one, HKK Bionics works in cooperation with German 3D-printing service bureau Teufel Prototypen and DyeMansion to deliver the right surface treatment and individual colors for their orthotics. Every orthotic is unique and customized.
Passed tests for cytotoxicity and skin irritation according to ISO norms and furthermore:
- matching skin tones
- improved & homogeneous haptics
- reproducible results for all the small parts being assembled to one orthotic
“With DyeMansion technology we are able to deliver finished and colored products that can be used in everyday life. The developed skin tones can help patients to identify with their orthosis and to accept it as an aid in everyday life. In addition, the existing certificates for cytotoxicity and skin irritation help us to pass relevant certifications and tests with the exomotion hand one.”

Case study: Quorum Prosthetics
The Quatro is an award-winning patented prosthetic that gives users the ability to adjust the volume and compression of the device
Quorum Prosthetics has been making custom prosthetics for almost 24 years now and got into Additive Manufacturing in 2020. Raw printed MJF parts are abrasive when coming out of the printer, making it tough for patients to wear prosthetics that have not been finished.
The material, Lubrizol's ESTANE ®* 3D TPU, is characterized by abrasion resistance and high mechanical properties which tend to complicate traditional vapor polishing. DyeMansion was able to create a new program for the Powerfuse S – designed specifically for this TPU to ensure a high level of smoothing that has not been achieved before with TPU.
Having it smoothed enables the patient to get in the prosthesis more easily and you even can achieve vacuum with a small part, which is quite important. Furthermore, it strengthens it too and makes it more comfortable for the patient to wear on a daily basis.
Case study: Gottinger
3D-printed leg Prosthetics
Gottinger Handelshaus OHG has been at the forefront of orthopedic technology since 1901. In 2012 it made Additive Manufacturing a core part of its technological skillset. To bring a 3D-printed medical product on the market meant that a lot of hurdles needed to be overcome. The request for a specific skin tone came from a patient.
Gottinger has successfully certified its SLS leg protheses according to the DIN EN ISO 10328: 2007 standard. Here, force, rotation, and resistance are tested. For this standard, 2,000,000 steps were simulated, which the prosthetic foot survived unscathed.
With DyeMansion, Gottinger found a reliable partner to fulfill their needs when it comes to a pleasant finish of their prosthetics. Together we were even able to dye the leg prosthetic in the patient’s skin color. For those patients who do not require skin tones, Gottinger is able to offer a wide array of different colors.
Case study: Avsar
3D-printed surgery guide
To create an exact surgical guide for patients that met biocompatibility standards and could be produced in a short amount of time. The surgical guides are used to show patients what outcome to expect from their reconstructive surgery (for example after a disconfiguring injury).
The use of 3D-printing along with DyeMansion post-processing technology allowed Avsar to exactly replicate the patient’s anatomy and skin-tone for each part. This could only be achieved due to the ability to print and finish complex objects and shapes that would otherwise not be possible to create through any conventional methods.
Avsar is able to create customized products fitted to each patient’s needs in a much shorter time than would be required with conventional manufacturing methods. The process is also very cost-effective, as there is no need to store large amounts of goods or materials.
