3D printed medical devices

Medical Device 3D Printing: Video Round Up

BY Nita Vaidya-Zannino

Medical devices are becoming smaller, more expensive to assemble, and used more commonly with collaborative robotics. Miniaturization, the cost of assembly, and the complexity of designing tools for diagnostic and surgical robots are just some of the challenges that today’s medical device designers face. That’s where medical device 3D printing comes into play.

BMF’s Projection Micro Stereolithography (PµSL) technology can 3D print medical devices with ultra-high resolution, accuracy and precision. PµSL can 3D print true microstructures with ultra-high printing resolution (2µm~50µm) and printing tolerance (+/- 10µm ~ +/- 25µm).

Below is a compilation of 3D printed medical devices fabrication on BMF’s microArch printers:

An Endoscope Shell

Endoscope shells cover the camera at the end of an endoscope. Here are the specs for the endoscope shell:

  • Printer Model – microArch S140
  • Dimensions – 9.8mm x 9.8mm x 13.8mm
  • Resolution – 10 µm
  • Tolerance – ±0.025mm
  • Features = tube diameter of 1.2mm, Minimum Wall thickness of 65 µm, several types of complex structures are included

Endoscope shells can be customized to the equipment’s needs. Here are the specs for another model endoscope shell:

  • Printer Model – microArch P140
  • Resolution – 10 µm
  • Tolerance – ±0.025mm
  • Tube Diameter – 1.2mm
  • Length – 4mm
  • Minimum Wall thickness – 65 µm
  • Features – several types of complex structures are included

A Cardiovascular Stent

Cardiovascular stents are implanted in the coronary artery to improve blood flow to the heart. Here are the specs for this stent:

  • Printer Model – microArch P140
  • Dimensions – 15.44mm x 3.42mm
  • Resolution – 10 mm
  • Tolerance – ±0.025mm
  • Features – flexible materials, rapid fabrication of complex structures

A spiral syringe needle

Spiral syringe needles are used for minimally invasive surgery. Here are the specs for this needle:

  • Printer Model – microArch S140
  • Dimensions – 12.5mm x 12.7mm x 10.35mm
  • Resolution – 10 mm
  • Tolerance – ±0.025mm
  • Features – integral forming of complex structures including threads, syringe, etc.; enough material strength for animal experiments, internal diameter of syringe = 0.25mm
