Rapid liquid 3D printing of patient specific wrist orthoses
Problem statement
Treating patients who suffer from wrist weakness or maladjustments is crucial for patient freedom of movement and physical comfort. However, an orthopedic surgeon should not be limited by the lengthy process of 3D printing a customizable wrist orthotic, nor should the surgeon be limited by the availability of a hand specialist. Custom wrist orthotics on the market today range in fabrication time from a day to sometimes a week [1]. An orthotist is also needed for the molding of the orthotic, and they are a resource that not every hospitable has full access to [1]. Rapid liquid printing (RLP), combats the time and limited access to hand specialist barriers. RLP uses gel as a support medium which increases the printing speed, allows for the printing of complex geometries using patient wrist scans, and can be experimented with many different materials [2]. Overall, RLP is a revolutionary method that encourages faster printing times, better healthcare access, and is considered a more affordable option that has the ability to cater directly to the patients’ needs for customizability. It is imperative that rapid liquid printing is further explored and researched so that an efficient and effective RLP method may be developed. Essentially, our solution will address the slicer and g-code, support gel and printing material, and process hardware to provide quality custom printing to provide the best comfort solution for the patient.
