Melt Deposition Modelling of Bioactive Organic/Inorganic Hybrid Scaffolds

Melt Deposition Modelling of Bioactive Organic/Inorganic Hybrid Scaffolds: Hybrid materials/ blends offer more potential to mimic artificial bones because of better biological/physical properties. E.g. cell adhesion might be much better than for pure PCL. 3D printing of such material, however, could be challenging due to difficult viscoelastic properties. A team at LPC lab (University of [...]

Peptide Chitosan/Dextran Core/Shell vascularized 3D Constructs for Wound Healing

Peptide Chitosan/Dextran Core/Shell vascularized 3D Constructs for Wound Healing: Vascularization is still a challenge when creating artificial tissue by 3D printing. New Zealand researchers successfully put a step forward using the core/shell extruder of the GeSiM bioprinter BS3.1. This tool prints two different materials in a coaxial manner. The team at University of Otago used [...]

An Animal Study for Insulin Delivery by Microneedles

An Animal Study for Insulin Delivery by Microneedles: Microneedle arrays are miniature puncturing devices that disrupt the skin barrier to deliver therapeutic agents trans dermally, in a pain free manner. Common drawbacks associated with typical microneedle coating techniques such as dip-coating, suffer from poor controllability of the outcome in terms of coating morphology, spatial deposition [...]

3D Printing of Bone Grafts for Cleft Alveolar Osteoplasty

3D Printing of Bone Grafts for Cleft Alveolar Osteoplasty: Cleft lip and cleft alveolar bone defects are congenital anomalies. They often require surgery during infancy and early childhood. Scientists of the Berlin Charité, the Dresden Technical University and the Zurich University conducted a promising animal study with rats. 3D-printed bone grafts with CPC (Calcium Phosphate [...]

Droplet mixing with piezoelectric pipets

Droplet mixing with piezoelectric pipets: GeSiM piezoelectric pipets emit drops smaller than 80 Micrometers at a speed of 4 meters per second. The TwinTip adapter swivels two of these pipets from parallel position (sample aspiration, wash step) to angled working position and vice versa. With appropriated reagents the TwinTip adapter can trigger chemical reactions at [...]

Micro-Needle-Arrays by NIL

Micro-Needle-Arrays by NIL: Micro-Needle-Arrays are currently in research but show a great potential for subcutaneous drug delivery through the outermost layer of human skin. Nano-Imprint Lithography (NIL) using GeSiM micro-contact printers is a smart approach for production of such 3D structures. GeSiM instruments are able to manage the high-aspect-ratio of the needles by evacuating the [...]
