Medical PLGA-HA
Medical-grade PLGA-HA filament is an advanced copolymer made of poly(lactic-co-glycolic acid) (PLGA) loaded with 10% hydroxyapatite (HA), a mineral naturally found in bone tissue. This implantable and bioresorbable material is designed to degrade progressively in the body within 12 to 24 months.
By combining the resorbable properties of PLGA with the osteoconductive nature of hydroxyapatite, this filament promotes bone integration and regeneration. With its ivory color and rigid behavior at room temperature, it is particularly suited for applications in bone reconstruction and tissue engineering.

Its technical characteristics
- Material: PLGA (poly(lactic-co-glycolic acid)) + 10% Hydroxyapatite (HA)
- Color: Ivory
- Finish: Rigid
- Diameter: 1.75 mm
- Spool Weight: 100 g – 200 g
- Origin: Made in France
- Implantable: Yes
- Resorption Time: 12–24 months
Its printing properties
For optimal print performance, the following parameters are recommended:
- Extrusion Temperature: 210 – 230 °C
- Bed Temperature: 55 – 65 °C
- Print Speed: 20 – 90 mm/s
PLGA-HA behaves similarly to PLA during printing, while requiring controlled environmental conditions to preserve its biomedical properties.
Its mechanical and thermal properties
- Rigid material at room temperature
- Amorphous thermoplastic
- Bioresorbable (12–24 months)
- Biocompatible
- Enhanced osteoconductivity due to hydroxyapatite
- Suitable for implantable applications
Its areas of application
Medical-grade PLGA-HA filament is particularly suitable for:
- Bioresorbable bone implants
- Orthopedic screws and fixation devices
- Bone reconstruction structures
- Scaffolds for guided bone regeneration
The combination of bioresorbable polymers like PLGA with bioactive fillers such as hydroxyapatite opens new possibilities for 3D-printed implantable medical devices, especially in bone regeneration.
