How Medical Device Companies Use MJF

š„ The Need for Agility in Medical Manufacturing
Medical device companies face constant pressure to innovate quickly, test thoroughly, and comply with tight regulatory standardsāall while managing cost and speed to market. Traditional manufacturing methods like injection molding or machining often canāt support that level of flexibility, especially in early-stage development.
Multi Jet Fusion (MJF) offers a powerful solution. It enables medical companies to produce functional, precise, and customizable parts without tooling delays, making it ideal for prototyping, bridge production, and even low-volume end-use components.
š§Ŗ Why MJF Is a Fit for Medical Applications
MJF produces parts in PA12 and PA11, two biocompatible thermoplastics with high mechanical strength and chemical resistance. Combined with isotropic material properties and high resolution, MJF parts are:
- Durable enough for field testing and clinical use
- Accurate enough for complex mating components
- Cleanable and chemically resistant to common sterilization methods (IPA, hydrogen peroxide vapor, etc.)
These traits make MJF a practical choice for many Class I and II medical applicationsāeven before regulatory clearance is finalized.
š§© Common Use Cases in Medical
RapidMade supports medical teams across a wide range of use cases, including:
- Custom housings and enclosures
Durable, lightweight, and printable in batches with slight variationsāideal for wearables or diagnostic devices. - Surgical planning tools and anatomical models
Printed from scan data to simulate procedures, train clinicians, or support patient-specific planning. - Functional test fixtures and jigs
For device validation, assembly, and QA processesāproduced faster and more affordably than machined counterparts. - Ergonomic handles and casings
Printed in short runs to test grip, balance, and feedback before tooling is committed. - Custom attachments and accessories
For wearable sensors, mobile carts, or disposable systems.
š From Prototype to Pre-Production
MJF allows medical teams to iterate fastādesign, print, test, and repeat in a matter of days, not weeks. Once a design is finalized, that same file can be used to print:
- Pilot batches for clinical trials
- Regulatory samples for testing and documentation
- Market-entry runs for limited release
This compresses the entire development cycle without compromising part performance.
š¦ Scalable Without Tooling
Unlike injection molding, MJF doesnāt require expensive molds or long lead times. That means you can:
- Run 500, 1,000, or 5,000 units with no tooling cost
- Update your design at any timeāno sunk mold cost
- Launch products faster and pivot without penalty
For Class I and II devices or custom accessories, this flexibility creates a huge advantage.
