Produce Replacement Parts with Additive Manufacturing

Imagine this scenario: A part on a very expensive machine or equipment breaks down, and you discover that the manufacturer no longer produces spare parts. Panic sets in – how can you keep your equipment running without that critical component?

Whit this case we will inspire how you to benefit 3D scanning, reversed engineering and 3D print when it comes to broken spare parts. By manufacturing your own parts that can replace what is broken, you not only reduce costs, but also time when production is standing still and environmental impact.

Protech was contacted by an owner of an older Yamaha snowmobile. The problem was that it was completely impossible to get hold of a spare part. With the help of Protech, the owner was able to receive a new part in a short time to replace the broken one. This success story isn’t limited to snowmobiles – it applies to any machinery, from industrial equipment to vintage snowmobiles.

Step 1: Scan

The first step was to scan the broken part. The part had very complex geometry but that wasn't a problem during the scanning process. Our application specialist used the FreeScan Combo 3D scanner from SHINING 3D . The data was extremely high detail.

Step 2: Reverse Engineering

The scan data was then imported into QUICKSURFACE where our CAD specialist could begin the digital repair and recreate the detail. QuickSurface contains great tools for Reverse Engineering, and combined with accurate and reliable scan data, many details could be completed quickly. Then the construction was exported to the CAD program TopSolid'Design where final detail modeling was done.

Step 3: 3D print

The final construction was then 3D printed in a Stratasys F770. The result was perfect on the first print and was able to replace the broken part directly on the scooter. The detail was printed in ASA, a material with high UV stability and strength, which is perfect for applications to be used in an outdoor environment.

Conclusion:

• Cost-Effective Repairs: Traditional manufacturing processes often involve high costs for tooling, molds, and production runs. With 3D printing, you can create custom parts on demand, eliminating the need for expensive setup.
• Time Efficiency: Waiting weeks or months for spare parts is frustrating. 3D printing enables rapid prototyping and production, reducing downtime.
• Eco Friendly Approach: By manufacturing only what you need, you minimize waste and contribute to a greener environment.

Next time your equipment faces a breakdown, consider additive manufacturing. Explore the endless possibilities of 3D printing, and reimagine maintenance and repair. Whether it’s a rare vintage tractor or a cutting-edge CNC machine, 3D printing empowers you to be self-reliant.

Remember: When spare parts become scarce, innovation steps in. Additive manufacturing bridges the gap, ensuring that your machines stay operational, costs stay manageable, and the planet benefits.
