Computer-aided manufacturing (CAM):
From a print file to a finished device


Computer-aided manufacturing (CAM), is a core part of the digital value chain if you are working digitally in the field of orthopaedic technology.

Always remain flexible: Whether you prefer to have a ready-modeled positive model milled or printed and then thermoformed, or you want to 3D print the fully designed orthotic blank. That is entirely up to you.

Hybrid or fully digital? You decide!

When you use the Mecuris Solution Platform, you always decide how deep you want to dive into digital manufacturing. Depending on the stage at which you end the digital processing, you choose between hybrid or fully digital manufacturing.

Hybrid manufacturing enables a gradual approach to digital fabrication: In this case, you create your previous plaster positive digitally by correcting the patient scan with the Mecuris3D Correction tool and modeling the positive model according using Mecuris3D Modeling.  The digitally created functional form can be downloaded and sent to a manufacturing partner for milling or 3D printing. The final orthosis blank is then manufactured as usual by hand using the thermoforming process.

Take it one step further with fully digital manufacturing: Based on the digitally corrected and modeled positive model, you now also create the orthosis blank digitally, using the Mecuris3D Creator. Then you print the blank conveniently with your manufacturing partner using high-quality 3D printing.

The CAD-manufacturing processes at a glance

Hybride Fertigung Zweckform

The positive model as the core of hybrid manufacturing 

In the hybrid manufacturing process, you traditionally produce the final orthosis blank in your own workshop e. g. using the thermoforming process. You have created and downloaded the required positive model digitally in the Mecuris3D Modeling tool instead of using plaster. It is then milled or 3D printed by a service provider or in-house.


Here's a brief overview of the processes: 


CNC milling (Computerized Numeric Control)

CNC milling ("Computerized Numercial Control") is a subtractive manufacturing process. In this method, the positive model is cut out of a block of material (blank) with the aid of milling or cutting tools.

FDM printing (Fused Depositioning Modeling)

3D printing processes are additive manufacturing processes. In FDM printing, the positive model is built up layer by layer from molten plastic. Simple and inexpensive FDM printing is ideally suited for manufacturing functional forms. For the production of an orthosis itself, this manufacturing process is currently ruled out for a wide variety of reasons - e.g. durability.

Choice of materials:

Hard foam

heat resistant and optimal
price-performance ratio

Choice of materials:

Polycarbonate (PC)

High melting temperature

Not suitable: Polylactide (PLA)

melting temperature too low for subsequent thermoforming process

Main advantages:

very precise due to computerized control technology

delivery of the functional form including reinforcement bar

Main advantages:

favorable machine and material prices

unproblematic in-house production

low percentage of waste

The orthosis blank in a fully digital production

In a fully digital production, you have digitally designed and configured the orthotic blank after modeling it in the Mecuris3D Creator. You then send the finished printing file to a 3D printing service provider after downloading it. Afterwards, you provide the delivered blank with closures and padding.

Due to the demands placed on an orthosis, we recommend that you place great value on the highest quality for 3D printing in terms of the resilience and robustness of the finished product. Two additive manufacturing processes are currently particularly suitable for this purpose: 


SLS printing (selective laser sintering)

In this process, a laser heats the powdered base material and fuses it selectively to the contours of the designed 3D file. 

MJF printing (Multijet Fusion)

Using infrared light and two reactants, the powdered base material is fused according to the geometry of the designed 3D file.

Materials and their benefits for both processes:

Polyamide (PA) PA11/PA12

> biocompatible and mechanically resilient

> finishing with grinding/coloring and painting possible

> high composite quality ensures high mechanical load capacity

> sharp edges and fine details possible

Polypropylene (PP)

> very high breaking elongation, low weight, good postformability

> especially well suited for cases where formability is particularly important

6 tips & tricks from the expert:

  1. Choice of hard foam for CNC milling 
    Choose a 90kg/m³ foam to achieve the best balance between cost, milling time, and post-processing capabilities.

  2. Thermoform with a polycarbonate (PC) positive model made by FDM printing
    Pull 1-2 socks over the model in order not to exceed the model's temperature of 135°C.

  3. PA 11 vs. PA12
    While PA11 is more ecological (castor oil base), has better elongation at break and flexibility, PA12 is more convincing in terms of robustness and production time/cost. PA12 is the "older" material and is used on more and larger machines. 

  4. Polypropylene (PP)
    Particularly well suited for applications in which formability is especially important - for example, in the care of (small) children.  However, the material cannot be dyed. It always comes in a somewhat yellowish white or in a pale/light gray. 

  5. In-house manufacturing
    The easiest way to get started in the 3D printing world is to have your own FDM printer, so you can make your purpose molds right in the shop or even realize test prints.

  6. Dyeing the SLS printed part
    Do you want to achieve long-lasting fresh colors? Then choose a UV-resistant ink.
