LutraCAD focuses on software solutions for the orthotics and prosthetics market. The company develops specialized software for the design and production of custom insoles, shoe lasts, midsoles, and related orthopedic products.
Since 2016, LutraCAD has been actively exploring 3D printing technologies to complement their clients’ digital workflows. Over the years, the team evaluated FDM, SLA, SLS, and other additive manufacturing techniques, with an initial focus on FDM due to its accessibility and ease of implementation.
However, as customer expectations evolved, particularly in the production of hard shell insoles, LutraCAD began exploring SLS more seriously. Many of their customers were already using SLS technologies, but LutraCAD had not yet found the right industrial solution that met their requirements.
That changed with the introduction of the Raise3D RMS220.
LutraCAD provides end to end workflow optimization for customers focused on the production of custom insoles tailored to individual patient needs. As demand increased, the company needed a solution that could better meet customer needs, delivering higher quality, improved productivity, and lower labor intensity.
Initially, LutraCAD worked with FDM technology. While suitable for early development, FDM quickly revealed limitations in surface finish, achievable thickness, and production efficiency.
At the same time, traditional milling methods presented their own challenges. Milling required constant operator supervision, generated significant material waste, and involved multiple post processing steps before a product was ready for delivery.
The search for a better solution led LutraCAD to Selective Laser Sintering (SLS) and ultimately to the Raise3D RMS220.
After testing different technologies, LutraCAD identified three decisive advantages of SLS:
Compared to FDM, SLS delivers a significantly improved surface finish and enables thinner insole designs without compromising performance. This is particularly important in orthopedic applications, where both comfort and structural integrity are critical.
The combination of SLS technology and high performance materials allows LutraCAD to produce insoles that are thinner, lighter, and mechanically reliable.
With the RMS220, LutraCAD can produce 20 to 25 pairs of insoles in a single build. Jobs run overnight, and by the next morning, a full batch is ready.
This is a major improvement compared to:
The ability to run unattended builds drastically increases daily output while reducing manual involvement.
In milling, up to 80 to 90 percent of the material block becomes waste.
With SLS, every part is built layer by layer from powder, and unused powder can be reused in future builds. This significantly reduces material waste and improves sustainability.
LutraCAD had already been using Raise3D FDM systems for several years. This long term experience built strong confidence in both the machines and the company.
When Raise3D introduced the RMS220 SLS solution, LutraCAD saw an opportunity to upgrade production while maintaining a trusted partnership.
Key factors behind the decision:
For LutraCAD, the RMS220 represented not just a machine, but a scalable production platform backed by a company they already knew and trusted.
