3D printing is producing a prodiscovered difference at the University of Malaya’s Centre for Biomedical and Technology Integration (CBMTI). CBMTI uses Stratasys’ PolyJet 3D Printing innovation to donate a range of services which include
custom medical implants, prototypes for new devices and patient-specific versions for surgical planning. But maybe the greatest impact is in creating sophisticated training simulators for clinical procedures.

At CBMTI’s inception, neurosurgeons were mentoring on live human cases, and practicing on cadaveric dissection and desktop simulations. Its initially 3D printing device turn it intod
spatially accurate versions in a single material, but did not mimic human pathology without a costly, time-consuming post system
. This changed when they acquired Stratasys PolyJet 3D printing innovation.

“Once we got the Stratasys multi-material 3D Printer, we were able-bodied to 3D print medical versions which
may, for instance, mimic the texture of the nose, the linings, and the harder tissue at the back of the nose. We discovered this quite useful, especially in teaching trainees how to handle different types of
materials,” said Vicknes Waran, MD, director of CBMTI.

Better Prepared with Realistic Patient-Specific Models

CBMTI now 3D prints detailed multi-material versions which
mimic real anatomy, actually down to a specific patient’s tumor. With access to high end multi-material 3D printing, CBMTI can fabricate versions which
showcase different types of
textures and densities over surfaces and throughout interiors, only as human body parts do.

“The [Stratasys]
J750 allows for us to turn it into versions with both texture and color variations which
mimic actual tissue handling and appearance advantageous
for these rigorous versions,” said Dr. Waran. “With the
Connex, we can simulate realistic layers of human tissue like skin, bone, dura, brain and tumors inside the 3D printed medical version for surgical simulations.”

Customizing the Training Model: How It Works

CBMTI develops its training courses in partnership with leaders in different types of
fields. Together, they elect a patient with the anatomy and pathology they wish to train physicians to treat. CBMTI engineers and so convert the patient’s CT and MRI scans into digital create files, and elect materials which
most match the physical, tactile and color characteristics of the target anatomy. CBMTI has actually discovered ways to use assist material, typically removed of the final version, to enhance clinical realism.

“We have in addition
incorporated showcases such as fluid dynamics so we can simulate endoscopic neurosurgical procedures,” said Yuwaraj Kumar Balakrishnan, CBMTI chief operations officer. “We find surgeons who train on these versions are much advantageous
made in terms of dealing with rigorous surgeries, just for the reason
they are able-bodied to train and retrain on the versions until they perfect
the procedure.”

Industry Leaders in Medical Models

Interest has significantly increased since CBMTI invested in 3D printing and the company has increased production ability by 40 percent with its 3D printing devices. A team of 20 medical clinicians, rapid-prototyping engineers, desktop programmers and electrical engineers work together on their main 3D printing lines of business: creating prototypes for university research, developing custom titanium implants and making custom simulators for surgical training.

“Researchers’ interest in our 3D printed versions has increased a hundredfold since we began via these 3D printing devices,” said Balakrishnan. “Stratasys 3D printing devices are the perfect platform for innovation.”
