Optimization of manufacturing process for SLM manufactured stents
Up to 20% of the Swiss population suffers from coronary heart diseases. Many of these patients need to undergo cardiovascular bypass surgery, a procedure that involves the connection of small blood vessels by a manual suture. In order to facilitate these kind of surgeries we have developed a novel stent-based connector that allows for easier and faster surgeries. This connector is manufactured by selective laser melting (SLM).
Although we have optimized the design to SLM design rules, there is still need of some support structures within the part. The goal of this project is to optimize the manufacturing process by investigating the removal of support structures during post processing. For this, you will evaluate the potential of hirtisation as a support-structureremoval-method on self designed testing samples. Once the procedure is defined, you will apply it to the existing parts of the anastomotic connector and hence enable reliable manufacturing of the implant.
