Louisiana Tech researchers use 3D printers to create custom medical implants

A team of researchers at Louisiana Tech University has developed an innovative method for using affordable, consumer-grade 3D printers and materials to fabricate custom medical implants that can contain antibacterial and chemotherapeutic compounds for targeted drug delivery.

The team comprised of doctoral students and research faculty from Louisiana Tech’s biomedical engineering and nanosystems engineering programs collaborated to create filament extruders that can make medical-quality 3D printing filaments. Creating these filaments, which have specialized properties for drug delivery, is a new concept that can result in smart drug delivering medical implants or catheters.

Jeffery Weisman, a doctoral student in Louisiana Tech University’s biomedical engineering program, uses a consumer-grade 3D printer and materials to create custom medical implant ‘beads’ that contain antibiotic and drug delivery properties.

“After identifying the usefulness of the 3D printers, we realized there was an opportunity for rapid prototyping using this fabrication method,” said Jeffery Weisman, a doctoral student in Louisiana Tech’s biomedical engineering program. “Through the addition of nanoparticles and/or other additives, this technology becomes much more viable using a common 3D printing material that is already biocompatible. The material can be loaded with antibiotics or other medicinal compounds, and the implant can be naturally broken down by the body over time.” … (Read more)
