Introduction

The field of medical device manufacturing has been growing rapidly in recent years, with advances in technology but also increased demand for healthcare products. From diagnostic equipment to implants and prosthetic devices, these medical devices play a crucial role in modern healthcare. 

CNC machining and injection molding are the two most common traditional manufacturing processes used for medical device manufacturing. However, additive manufacturing is becoming an interesting alternative for the medical sector. 

In this article, we will discuss what you need to know about medical device manufacturing and review the different manufacturing processes that could be adapted to your potential project.

What is medical device manufacturing?

Medical device manufacturing refers to the process of designing, developing, testing, and producing medical devices.

Medical device prototyping is also a crucial step in this process to ensure the development of the medical product. Testing and first validations are mainly depending on those prototypes and iterations.

When we talk about medical devices, this includes a wide range of products such as surgical instruments, diagnostic equipment, implants, prosthetics, orthotics, tools, training models, etc. As you might know, medical devices must meet strict safety and quality standards before they can be sold to healthcare providers.

What are the different key considerations in medical device manufacturing?​

Medical device manufacturing is complex and there are several key considerations to keep in mind. These include:

  • Regulatory Compliance: Medical devices must meet strict regulatory standards set by the FDA (Food and Drug Administration) to ensure patient safety. Manufacturers must comply with these regulations throughout the entire product lifecycle, from design to production to post-market surveillance.
  • Quality Control: Quality control is critical in medical device manufacturing. Medical manufacturers must have robust quality systems in place to ensure that their products meet the required specifications and standards.
  • Cost: Medical device manufacturing can be expensive, particularly for complex devices such as implants or customized devices such as orthotics. Manufacturers must balance the cost of production with the need to produce safe and effective devices.
  • Innovation: Innovation is key in the medical device industry and that is why this industry is constantly evolving! Manufacturers must continue to develop new and innovative products to meet the changing needs of healthcare providers and patients.

Medical device manufacturing: What kind of applications are we talking about?

When we talk about medical device manufacturing, it regroups a large range of applications, from heart valves and hearing aids to medical tools and surgical guides. Established technologies as well as new cutting-edge technologies such as 3D printing.

  • 3D printed enclosures
  • Device prototyping for modeling and validation
  • Custom and complex geometry device
  • Modeling for simulation and training for medical professionals
  • Personal protective equipement

Medical device manufacturing: What about regulations?

In the US, medical devices are regulated by the FDA (Food and Drug Administration). The main areas covered by these regulations are: Registration, Medical Device Listing, Premarket Notification, Premarket Approval, Investigational Device Exemption, Quality, System Regulation, Labeling, Medical Device Reporting.

In Europe, you can access all the regulations regarding medical device manufacturing on the website of the Europe Commission, dedicated to this subject.

What are the processes used for medical device manufacturing?

A number of parameters need to be considered will choosing a manufacturing technique for your medical device. Do you need custom parts? Is it a prototype or an end product? Is it a large or low-volume part?

Let’s review the different manufacturing possibilities you have to see which one could be the most adapted to your medical project.

  • CNC Machining

CNC Machining is a subtractive manufacturing technology where parts are created by removing material from a block by using a variety of cutting tools.

CNC Machining is best suited to manufacturing large series of medical devices as well as parts with complex geometries. This technology is adapted to higher volumes. 

Also, because of machine costs, training, etc. CNC machining offers quite a high start-up cost, and it won’t be possible to create custom or low-volume parts.

  • Injection Molding

Injection molding is also best suited for high volumes. Indeed, this manufacturing method is particularly helpful for mass production and will offer interesting material options with strong and durable plastics.

This is one of the most common manufacturing techniques, as almost everything around us is manufactured using injection molding. 

  • 3D printing

3D printing is a technique that builds objects layer by layer from a 3D file. The process is literally giving you the ability to transform a digital version of an object into a physical version. 3D printing is a manufacturing technique, more and more used today to make proofs of concepts, prototypes, or end-products. Companies are implementing 3D printing at different stages of their manufacturing processes and rethinking their business strategy with this competitive advantage. Medical 3D printing is also becoming quite common.

It is a real asset for medical device manufacturing. It offers interesting material options,

great technologies, and happens to be a real asset for design freedom as well as for mass customization

Focus on Additive Manufacturing: Why could it be the perfect manufacturing technique for your project?

What technologies should you use?

  • Selective Laser Sintering

Selective Laser Sintering (SLS) a versatile solution for your medical projects. Both for prototyping and functional products, and for small to medium production runs. SLS creates parts additively by sintering fine polymer powder particles to fuse them locally. Your plastic piece will be created layer by layer, according to your 3D model. 

  • Multi Jet Fusion

HP Multi Jet Fusion (or MJF) is an additive manufacturing method invented and developed by the company Hewlett-Packard (HP). It creates parts additively thanks to a multi-agent printing process. Your plastic part will be created layer by layer, according to your 3D mode

TPU

TPU

Ideal for shock-absorbing, elastic, and wear-resistant applications

PA11

PA11

Ideal for impact-resistant, functional prototypes and industrial components.

Nylon PA12 3D printing plastic

PA12

Ideal for strong, accurate functional prototypes and industrial components.

Nylon PA12: An interesting substitute for injection molding for medical tools and prrosthetics

Ultrasint PA11:  Based on 100% renewable biomass sources, PA11 is a more sustainable option if you are looking for a versatile plastic

Ultrasint® TPU: Highly flexible plastic, this TPU has good shock absorbing properties, which is quite ideal for orthopedic models.

PP: PP is perfect for manufacture-resistant and custom-made tools. Get tools or surgical guides adapted to your tasks and meet your professional requirements and constraints.

    • Stereolithography 
    Stereolithography (SLA) is a resin 3D printing technique where the liquid polymer is exposed to light when the build plate is incrementally moved, and the UV laser uses this exposure to create a cross-section. This is a layer-by-layer process that is repeated until a model is produced.
