Costs can be significantly reduced by using additive manufacturing over traditional casting manufacturing methods, according to Precision ADM.

WINNIPEG, MB (Canada)—Precision ADM, Inc., a global provider of engineering and additive manufacturing services, recently released a new white paper explaining the additive manufacturing and development process in a case study of the manufacture of a customized surface-guided knee implant.

The case study found that unique geometry, such as a patient-optimized knee implant, lends itself to the flexibility of additive manufacturing. By contrast, traditional casting manufacturing methods that deviate from set sizes can be penalized with high production costs.

The white paper explores the results of kinematic validation simulation testing on the implant done by the Orthopaedic Innovation Centre. The use of additive manufacturing and key post-processing operations on this customized knee implant resulted in samples that exceeded expectations in multiple ways. For one, the surface polish was mirror-like and exceeded specifications. Also, the complex and customized shape was highly accurate, which allowed the testing to replicate knee movements that were in close agreement with the in-silico simulations of the implant.

“The flexibility of additive manufacturing to accommodate unique designs is not nearly as cost prohibitive as traditional manufacturing,” commented Martin Petrak, CEO of Precision ADM, in a press release. “It is possible to provide superior medical devices that could improve patient outcomes while lowering overall costs.”
