Customized Prosthetics Using the EinScan 3D Scanners

September 16, 2019

In the world of 3D scanning and 3D printing, reverse engineering is the most commonly used application across multiple industries.

Being able to 3D scan an object and create a customized product is an invaluable skill. 3D scanners allow for the capture of organic and inorganic shapes alike, making them the ideal tool for industries that would struggle with traditional CAD design methods. One such industry is prosthetics. While the functionality of a prosthetic limb is its most important feature, the fit and form of the prosthetic can be just as important for the patient. The comfort a well-fitting prosthetic provides can make a world of difference as does the confidence provided by a prosthetic limb that suits its user’s appearance. 3D scanners have opened a gateway into customization, and customized prosthetic solutions are now a reality for many amputees. The EinScan Pro line of handheld 3D scanners, and the SHINING 3D industrial 3D printers, make 3D scanning and 3D printing for medical applications more accessible than it has ever been.

The EinScan Pro and Pro 2X line of scanners are as ambitious as they are multifunctional. The handheld capability of the scanners allows them to scan larger objects with ease and make scanning human body or human body parts a simple task. SHINING 3D’s flagship scanner, the EinScan Pro 2X Plus, can scan a human leg in a matter of seconds and the captured scan data can be processed, customized, and 3D printed faster than has ever been possible. We’ll explore just how easy it is to customize prosthetics shell using the EinScan Pro line of 3D scanners.

We begin by taking a 3D scan of the patient’s prosthetic leg. Using the EinScan Pro+ Handheld Rapid Scan mode, the scan is taken within a matter of seconds. The collected scan data is accurate enough to reverse engineering and allow for the creation of a customized prosthetic shell. A separate scan of the patient’s other leg is taken as a reference. This gives us an accurate representation of the overall size and form of the patient’s leg. The goal is to make the prosthetic shell as close to the real leg as possible.

Once the data is captured and the scan completed, the file is exported directly into Geomagic Essentials. 3D System’s Geomagic Essentials is the ideal bridge for 3D scan to design solutions. Working with organic shapes in CAD environments can prove to be a difficult task for even the most seasoned veterans, but the tools provided in Essentials allow for the seamless transition of your 3D scans into your native CAD platform.

The prosthetic’s scan data is imported into Essentials where the data can be cleaned up. Coordinates are assigned onto the 3D model making it easier for reverse engineering. The contours and overall shape and geometry of the piece are extracted and defined using the available tools.

From there the 2nd set of scan data, the patient’s leg, is imported into Essentials. The process is repeated, and the 3D model is prepped for reverse engineering.

Once both sets of data are properly aligned and processed, they are exported into Solid Edge SHINING 3D Edition. Solid Edge is a professional CAD software that allows for the reverse engineering of 3D scans. The software allows for both scans to be imported directly. The 2 models are reverse engineered individually. The prosthetic is used as the mechanical part of the CAD model while the scan of the leg is used as the reference for the shell around the prosthetic. The design and shape of the shell is customized using the scan from the patient’s leg.

 

Once the shell overall design is complete the Generative Design function of the software is used to finalize the design given the parameters of the 2 parts. The result is a completely functional prosthetic shell that accounts for the patient’s weight and the forces that are applied when running, walking, or other physical activities.

The customized 3D model is then saved and printed using SHINING 3D’s EP-P3850 SLS 3D printer. The completed print is then post processed and prepared for the patient. The printed shell fits perfectly into the patient’s prosthetic leg.

The EinScan Pro line of handheld 3D scanners makes 3D scanning for medical applications more accessible than it has ever been. SHINING 3D’s RED Bundle provides everything necessary for complete 3D Scan to Design solutions and industrial grade 3D printers like the EP-P3850 bring to these designs to life with amazing precision. Customization has never been more accessible. SHINING 3D brings you the complete 3D Scan-Design- 3D Print solution.

Elements of 3D Printing in the Classroom

August 6, 2019

Daniel Aktas is an art and technology instructor, also known as the “3D Printing Teacher” within his district. He incorporates 3D printing into most of his courses and he works with the 4 elementary schools in the district to facilitate an annual 3D printing immersion event.

Coming this November, he will be presenting at the 2019 New York State Art Teachers Association (NYSATA). He plans on showing how he incorporates 3D printing in his classroom and also sharing information about the Afinia H400 3D printers his students use.

Building Skills with 3D Printing

July 19, 2018

Brian Wagaman has taught Woodshop, Engineering and Technology, and Advanced Manufacturing and Logistics. He also served as the Vice President of the Association for Career and Technical Education (ACTE) for Indiana from 2016-2017. Wagaman focuses on giving kids the knowledge and skills pertinent to what they’ll experience in the world.

Taking Off with 3D Printing

Brian Wagaman’s classes were recently introduced to 3D printing when their school acquired an Afinia H400 and the Dobot Magician robotic arm. “I’m extremely impressed and excited about the machines,” explains Wagaman. “The students have taken off with them. The 3D printer has had nonstop use for months!” [Read more…]

Tech Ed Students Add 3D Printing to Arsenal of Tools

May 30, 2018

David Shircliff is the Technology Education teacher for Loudoun County schools. He has been teaching for 26 years, and loves when students have the “ah-ha” moment when they figure something out for themselves.

A Surprise Start to 3D Printing

Prior to the school purchasing the Afinia H800 3D printer, David Shircliff did not have experience with 3D modeling or printing. “It was actually a surprise when we got the 3D printers [Read more…]
