In plastics, EOS laser-sintered nylon is increasingly being used and researched for disposable, customized operating devices such as drill guides for knee and hip replacements. The same polyamide formulation has seen service in a lightweight, robust and durable orthesis, designed to precision measurements of a patient’s limb. EOS’ new PEEK HP3—a high-temperature, high-performance thermoplastic—is biocompatible and sterilizable, making it potentially well-suited for spinal implants.

In metals, direct metal laser-sintering (DMLS) systems are currently used to create:

  • Stainless-steel prototypes for customized spinal surgical instruments

  • Cobalt chrome replacement knee joint prototypes, and end-product dental copings and bridges

  • Titanium dental implants with porous surfaces that promote osteointegration

Control options include (now available for DMLS) an Integrated Process Chain Management system that provides quality assurance for re-using metal powder; and, (for plastics laser-sintering) a series of Part Property Profiles (PPP) that offer five different parameter settings for standardized, cost-effective part production.
