The industrial uptake of Additive Manufacturing and 3D printing processes is growing rapidly but is being hampered by the lack of breadth of materials usable in such systems. Identifying, and then optimisating formulations for 3D printing is time consuming, and generally involves many tedious steps each of which require lengthy analysis.Continue reading “Formulating for 3D printing of pharmaceuticals”

A virtual “dry run” and prior optimization of manufacturing processes is already common in many industrial fields. Also in medical applications it can help to achieve better quality faster and less costly. This applies for single individual parts as well as for serial production. Current capabilities, benefits and open challenges of additive manufacturing simulation for medical applications are discussed.Continue reading “Simulating Additive Manufacturing – Optimizing quality, time & costs”

Simulation of additive manufacturing processes gets more and more powerful and widespread in industrial applications. Also for medical applications the simulation of the production before the real print offers valuable benefits. Manufacturing problems can be identified in advance and countermeasures developed before a print fails. For geometrical critical applications the distortion prediction and compensation is very helpful.Continue reading “Simulation of Additive Manufacturing for medical applications – Current capabilities, benefits and open challenges”
Process with ceramic filled resins for stereolithography-based additive manufacturing of Bonelike Materials – Presented by Jaco Saurwalt, Admatec Europe, at 3D Medical Conference 2019.
Additive manufacturing technologies have expanded the possibilities of ceramic processing. In parallel, their introduction to the market has enabled the discovery of new applications for ceramics.
Among all additive technologies, stereolithography-based (SLA) techniques have the most potential because of their high precision and because the final properties of the printed parts are comparable to traditional advanced ceramics.

M3dRES – Additive Manufacturing for Medical Research and Education – Presented by Ewald Unger, Medical University Vienna, Center for Medical Physics and Biomedical Engineering, at the 3D Medical Conference, which takes place on January 30-31, 2019, at MECC Maastricht, The Netherlands.
In the last few decades Additive Manufacturing (AM), colloquially known as 3D printing, has been rapidly adopted as a cutting-edge technology gaining more importance in medical applications. Novel ideas for medical treatments using AM has reached maturity in this new field of research, with an increasing number of publications and the establishment of educational programmes in Universities across the globe. The uniqueness of AM in producing customized models with high accuracy allows planning and training of critical operations and traching of advanced medical strategies for a better patient support.

Bioinspired Heart Valve Prosthesis and Cellular Scaffolds by Silicone 3D Printing – Presented by Fergal Coulter, ETH Zurich – Complex Materials, at the 3D Medical Conference, which takes place on January 30-31, 2019, at MECC Maastricht, The Netherlands.
Artificial heart valves are highly demanded medical devices, but suffer from inferior performance compared to their biological counterparts. To tackle the poor longevity and hemodynamic behavior of many synthetic valves, an additive manufacturing platform was developed that enables the fabrication of polymer heart valves that are customizable to the patient and feature unique biologically-inspired leaflet designs.
Exploiting the shaping freedom of additive manufacturing, the synthetic valves are customized using geometries tailored to fit the anatomy of the patient. The architecture of the leaflet is designed to mimic the fiber reinforcement found in a natural valve.

Additive manufacturing a novel titanium dental implant abutment – Presented by Les Kalman, Research Driven at the 3D Medical Printing Conference, which will take place on 30-31 January 2019 at MECC Maastricht, The Netherlands.
Dental implants are an important elective option for the replacement of a missing tooth or teeth. The abutment acts as an interface between the implant and artificial tooth/teeth. A novel dental implant abutment, that provides a simple, efficient and inexpensive alternative for tooth fabrication, has been developed, patented and termed Tempcap.
The initial (traditional) prototype was fabricated by laser welding components but resulted in a weak structure with excessive variability in design. Manufacturing through conventional machining proved too costly and complicated. Additive manufacturing was investigated as an alternative to fabrication. The prototype was digitized and refined through CAD and initially printed in Duraform 316L stainless steel. The prototypes were qualitatively assessed for functionality by implant threading and successful simulated fabrication of an artificial tooth in a laboratory setting.
Based on the final optimized design, Tempcaps were 3D printed in dental-grade Titanium (Ti-6Al-4V) (ADEISS, London, ON). Complimentary to the 3D printing process, all Tempcaps underwent post-processing, which included final thread tapping for pronounced thread geometries, heat treatment for relieving thermal stresses and strengthening, and bead blasting for a smoother finish.
The final research objectives are: (1) to compare the maximum torques experienced during insertion of conventional and 3D printed Tempcaps into dental implants and (2) to assess the mechanical strength of the retentive pin projections under compression.
Results will be obtained this summer. The research will provide the necessary results required to verify and validate the 3D printed Tempcap for a clinical assessment. Continue reading “Additive manufacturing a novel titanium dental implant abutment – Presented by Les Kalman, Research Driven”
