No Tooling Costs, No Setup Fees and No Sacrifice in Performance
Traditional plastic manufacturing techniques like machining or injection molding require tooling and other setup costs for every project. This leads to a higher cost per unit on small runs and a longer production schedule.
MJF 3D printing with the HP Multi Jet Fusion enables businesses to manufacture plastic parts without any tooling or setup costs, saving time and expense. This allows for highly customizable, agile manufacturing with excellent value for small- to medium-sized production runs. In our fast-paced modern economy, 3D printing can help improve businesses’ competitive advantage by taking products to market faster and at less cost than ever before.
RapidMade provides durable 3D printed nylon and rubber-like TPU parts at a lower cost than traditional manufacturing methods, with typical lead times of 2–5 business days. Our streamlined digital workflow also enables on-demand ordering, reducing the need for large inventories or upfront commitments.
Beautiful detail and surface finish is the standard
The Fastest 3D Printer
Despite its compact size, the HP Multi Jet Fusion is one of the fastest 3D printers available, offering production speeds up to 1000 times faster than other 3D printing technologies and delivering cost reductions of up to 80% compared to SLS and FDM.
So, what’s the catch?
There isn’t one! In addition to being cheaper and faster, the HP Multi Jet Fusion 3D printing process offers superior surface finish, detail resolution, and strength when compared to ColorJet, selective laser sintering (SLS), fused deposition modeling (FDM), and stereolithography (SLA).
Whether you are in product development, small-batch manufacturing, or product maintenance RapidMade and HP MJF printing with fusion technology will provide measurable benefits to your production on the first run.
¹ Compared to typical costs and print times for Colorjet, FDM, SLS, SLA and other standard 3D print technology.
² Compared to typical tooling/part cost and lead time of 4 – 8 weeks, order sizes of 100 – 1000 units.
³ Compared to typical cost and lead time of 3 – 6 weeks for plastic parts, 1 – 1000 units.

Nylon PA-12: A Better and Stronger Printed Part
With 3D printed nylon parts, you get industrial-strength products with guaranteed precision, every time. The production-grade nylon PA-12 used by the HP MJF 3D printer offers unprecedented jetting mechanical strength for 3D printed plastic parts, along with an excellent strength-to-weight ratio and high-quality surface finish.
Nylon PA-12 offers exceptional value and performance for functional prototypes, industrial-grade components, and consumer products, outperforming most other 3D printed plastics available today.
Its fully dense and nearly isometric mechanical properties ensure strength and durability on every axis. Nylon PA-12 has high chemical and heat resistance and boasts a part accuracy of +/-.008”.
Nylon 12 can print free-standing walls as thin as 0.020″ (0.5mm)

No More Injection Molding: TPU for Flexible and Abrasive Applications
The Multi Jet Fusion process is also compatible with flexible, rubber-like thermoplastic polyurethane (TPU). TPU is softer and more flexible than nylon PA-12 but offers comparable detail and finish. Processing parts with high chemical, thermal and abrasion resistance, plus a high tolerance for oil and grease, TPU is perfect for common rubber parts like gaskets, seals, and hoses.
Elastomers have traditionally been challenging to 3D print and unsuitable for machining, often requiring costly and time-consuming injection molding or casting. With modern advancements, high-quality rubber parts can now be produced in as little as two days, without the need for metal molds.

3D Printed Rapid Tooling: Molds for Forming and Casting, Resilient Jigs and Fixtures
Because of its fine detail, high speed and low cost, the Multi Jet Fusion (MJF) is ideal for quickly producing tooling for use with other manufacturing technologies. That means that you can use MJF 3D printing to optimize your supply chain even if your end product is thermoformed, cast or injection molded. Nylon PA-12 is particularly compatible for tooling; it has a relatively high temperature resistance and does not bond with other materials, so MJF printed tools can produce thousands of forms.
3D printed tooling and master patterns can help businesses get the most from their product development cycles by reducing the cost and time of iteration. Moreover, when combined with a technology like urethane casting, 3D printed master patterns can produce very inexpensive parts that rival the quality and detail of injection molded parts in a fraction of the time.

FAQs on HP Multi Jet Fusion
What is the best 3D printing technology for low-volume production runs?
How does MJF 3D printing compare to injection molding for small batch manufacturing?
For runs under 500 units, MJF almost always wins on cost and speed. Injection molding requires $5,000–$50,000+ in tooling and 4–8 weeks of lead time before a single part is made. MJF has zero tooling costs and parts ship in days. MJF nylon PA-12 parts have mechanical properties approaching injection-molded nylon, with the added benefit of geometric freedom — you can print internal channels, lattices, and complex assemblies that molds simply cannot produce. RapidMade can help you evaluate the crossover point where injection molding becomes more economical for your specific part.
Is MJF 3D printing suitable for aerospace and defense applications?
Yes. MJF nylon PA-12 carries UL 94-HB flame resistance certification and meets FST (flame, smoke, toxicity) requirements for many aerospace applications. RapidMade is both ISO 9001:2015 certified and ITAR registered, meaning we can handle export-controlled defense work with full regulatory compliance. We provide First Article Inspection Reports (FAIR), Certificates of Conformance, and full traceability documentation required by aerospace and defense primes.
Can MJF parts be used in medical devices?
Yes. HP’s MJF nylon PA-12 is certified to USP Class I–VI for biocompatibility, meets ISO 10993-5 and ISO 10993-10 standards for cytotoxicity and skin sensitization, and is suitable for FDA Class I intact skin surface devices. RapidMade regularly produces medical device components, housings, and surgical tool prototypes using MJF. Our ISO 9001 quality system ensures full traceability and documentation for regulated environments.
What is the cost of MJF 3D printing per part?
MJF is typically 50–80% less expensive than SLA or FDM for production quantities, with per-part costs often ranging from $5 to $150 depending on size and complexity. Because MJF builds an entire powder bed at once, cost per part drops significantly as quantities increase — unlike other 3D printing methods where cost stays relatively flat. RapidMade offers instant online quoting so you can see exact pricing for your specific geometry within seconds.
What surface finishes are available for MJF 3D printed parts?
MJF parts come standard with a fine, uniform matte gray finish. RapidMade offers multiple finishing options including custom Pantone-matched automotive paint (Genesis finish with 10-year UV protection), ESD coating for electronics applications (certified 10⁷–10⁸ Ohms surface resistance), vibratory tumbling for a satin sheen, threaded insert installation, and post-CNC machining to achieve tolerances as tight as ±0.001″ on critical features.
