BellaSeno GmbH, a medtech firm specializing in additive manufacturing applied sciences, has showcased the biomechanical properties of its 3D printed, resorbable scaffolds for bone reconstruction.

Massive long-bone defects and non-unions are historically handled utilizing the diamond idea, which includes inserting an osteoconductive scaffold to information bone regeneration. Additive manufacturing has allowed for the event of personalized scaffolds to match the affected person’s anatomy. BellaSeno employs both selective laser sintering (SLS) or fused deposition modeling (FDM) relying on the required properties of the scaffold.

In a research, BellaSeno in contrast how SLS and FDM have an effect on the biomechanical properties of polycaprolactone / hydroxylapatite (PCL / HA) scaffolds for bone regeneration. The outcomes confirmed that FDM scaffolds demonstrated superior mechanical stability, with no fatigue noticed below axial hundreds as much as 1,000 N. In distinction, the SLS fabricated scaffolds exhibited decrease mechanical integrity, failing below an axial load of 700 N.

Dr. med. Tobias Grossner, Chief Medical Officer of BellaSeno, emphasised the impression of FDM expertise on the axial mechanical stability of the ultimate product. CEO Mohit Chhaya highlighted FDM because the extra strong and cost-effective expertise for scaffold manufacturing, whereas acknowledging that SLS affords benefits in situations requiring increased design freedom.

BellaSeno’s ISO 13485-certified manufacturing processes allow the scalable manufacturing of custom-made and off-the-shelf sterile medical implants. Preliminary findings from ongoing Part I research point out the security, tolerance, and assist for pure tissue progress of BellaSeno’s resorbable implants.

The corporate offered the comparative knowledge on the twenty fourth EFFORT Congress in Vienna, Austria, which demonstrated that BellaSeno’s manufacturing course of produces scaffolds that may face up to increased hundreds and longer stress cycles in comparison with competing applied sciences.
