3D Printing Processes for Medical Applications


Direct Metal Laser Sintering (DMLS)

Often known by the familiar phrase direct metal laser sintering, DMLS prints high-resolution parts to permit metal instrumentation design. DMLS makes it possible to design specialized, end-use surgical tools and have them in a surgeon’s hands within days. Moreover, cobalt chrome and titanium are ISO 13485 certified. 

Stereolithography (SLA)

SLA uses a UV laser to solidify resin held in a tank. If precision is important, SLA provides high accuracy and can yield features as small as 0.002 in. (0.051mm). SLA offers some unique material options, such as ultra-high resolution MicroFine™ in gray or green, and rugged Ceramic-Like Advanced HighTemp (PerFORM). Another option, True Silicone, can create parts that mimic the look and properties of liquid silicone rubber (LSR), but offers more geometric flexibility than possible with injection-molded LSR parts.

 

Multi Jet Fusion (MJF)

MJF offers material versatility and creates complex, functional parts with highly isotropic properties. This process allows for printing of multiple parts within the same build. The end-use parts can include lightweight, yet strong, prosthetics that allow for sterilization and autoclaving.

Selective Laser Sintering (SLS)

SLS is not unlike its cousin DMLS in that it uses a laser to solidify powder in a bed, but the materials here are plastics. It produces accurate prototypes and functional production parts in as fast as 1 day using a variety of nylon materials and the thermoplastic, TPU. It quickly builds highly durable final parts in materials that exhibit heat resistance, chemical resistance, flexibility, and dimensional stability. Vapor smoothing is available as a post-processing option to eliminate rough surfaces and yield a glossy finish.

 

PolyJet

This process allows for the use of multiple colors or durometers in a single part build and can even do that within a single build layer. For the medical industry it makes sense when prototyping orthopedic implants and dental prostheses for fit-testing. You can even create soft grips on hard plastic surgical instruments. PolyJet can mimic various polymers, including liquid silicone rubber (LSR) and ABS, and can even simulate elastomers or flexible parts.

Advanced Photopolymers

Hybrid PhotoSynthesis (HPS) parts have all the advantages of other 3D printing technologies, including the ability to create highly organic forms. HPS goes further, however, by offering greater speed than stereolithography, near-isotropic parts (equal strength along all axes), and high-resolution features using production-grade material.

Fused Deposition Modeling (FDM)

This fast, affordable technology directs heated thermoplastics through a nozzle to build parts. It offers a selection of material choices that address the needs of medical manufacturing, including biocompatibility, heat and chemical resistance, and more. It’s a great solution for custom prosthetics and anatomical models.

 



3D Printing Applications in the Medical Industry 

Thanks to advancements in additive manufacturing technologies, the medical industry is continuously leveraging 3D printing for a wide array of innovative products. 

Enclosures and Housings

3D printing allows for rapid prototyping and production of customized housings. This enables manufacturers to quickly iterate and test designs and produce intricate shapes other manufacturing methods cannot.


 

Microfluidics

3D printing is an excellent choice due to its ability to fabricate complex, multi-layered internal channels and geometries with high precision. It offers a fast, cost-effective way to produce intricate microfluidic parts that require very fine, accurate structures.

 

Prosthetic components

3D printing is uniquely suited to manufacturing prosthetics because it excels at creating custom-fit, lightweight, and affordable parts. This significantly improves comfort and functionality, especially for growing children who need frequent replacements.

 

Surgical instruments

On-demand production of patient-specific and procedure-specific tools is a core use for medical 3D printing. It can improve surgical precision and efficiency, reduce costs, and allow for the development of specialized instruments with complex features not possible with conventional methods.
