3D Printed Plastic: 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.

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 offers durable 3D printed nylon and rubber-like TPU products below the cost of traditional manufacturing that ship in 1-5 business days. Plus, our digital workflow means that you can order more units whenever you need them, eliminating the need for large inventories and upfront orders.

The Fastest 3D Printer

Don’t let its size fool you: the HP Multi Jet Fusion is the fastest 3D printer in the world, with industry-leading production speeds up to 50 times faster with printing materials than other 3D printing technologies land cost reductions of up to 80% in comparison to SLS and FDM.

So, what’s the catch?

There isn’t one! In addition to being cheaper and faster, HP Multi Jet Fusion 3D printing 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 Multi Jet Fusion printing with fusion technology will provide measurable benefits to your production on the first run.

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 Multi Jet Fusion 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. For functional rapid prototypes, industrial-grade parts or consumer products, nylon PA-12 provides superior value and performance compared to any other 3D printed plastic on the market.

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”.

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.

Historically, elastomers have been particularly difficult to 3D print and impossible to machine, forcing businesses to rely on expensive and time-consuming injection molding and casting. Now, you can ditch the costly metal molds and start manufacturing high-quality rubber parts in as few as two days!

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 form.

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.

Increased Competitive Advantage Throughout Product Life Cycles

The high speed and low cost of Multi Jet Fusion 3D printing makes it possible to add value at every stage of your product life cycles. Beginning with product development, MJF can quickly print functional prototypes and proofs of concept, allowing you to take your product through more iterations in less time and get to market even faster. This developmental advantage also translates to other manufacturing technologies: MJF can create durable tooling for thermoformed or cast urethane parts in a fraction of the time and cost of traditional methods.

It’s not just prototypes—MJF is an excellent choice for initial production runs or other low-volume manufacturing. Because of their unique design possibilities, 3D printed parts allow manufacturers a variety of opportunities to decrease cost and improve functionality, whether by combining multi-piece assemblies into single parts, reducing part weight with internal lattice structures, or using just-in-time manufacturing to reduce inventory and overhead.

Consistent quality over large production runs

MJF 3D printing can even help you extend product life cycles by providing affordable on-demand replacement part production, eliminating the need for unnecessarily large volumes of replacement parts and the accompanying inventory. Similarly, MJF parts can easily replace discontinued or expensive replacement parts for existing equipment. These parts can even be customized to improve their function.

To go into more depth about all of the benefits and guidelines for 3D printing, we put together an informative Design for Additive Manufacturing (DfAM) Guide to help you get started thinking about 3D printing.
