Rapid 3D printing

3D printing (additive manufacturing) rapid prototyping service encompasses different 3D printing technologies:
Our 3D printing rapid prototyping services are ideal for 3D printed plastics and metals, with extensive material and finishing options available. These additive manufacturing technologies can also sometimes be used for production. Because 3D printing doesn’t require tooling, prototyping of 3D printed parts takes only a short time, without sacrificing build quality. Other advantages include geometrical freedom and affordability, especially in low volumes. 3D printing is often preferred for concept models, but precision technologies SLM can also work for functional prototypes and even production parts.
  • FDM — Low-cost plastic parts prototyping
  • SLA — Plastic parts prototyping with exceptional surface finish
  • SLS — Strong prototyping parts in nylon or nylon glass
  • SLM — Metal parts prototyping in steel or titanium

Rapid CNC Machining

operates a large number of CNC machining centers, mills, and lathes (for CNC turning), enabling rapid prototyping of CNC machined parts made from plastic or metal. We offer a wide range of material and finishing options and the potential to combine CNC machining with other rapid prototyping processes. CNC machining is one of the most high-precision rapid prototyping technologies available. Although rapid CNC machining prioritizes short turnarounds over ultra-tight tolerances, the quality remains high. Turnarounds are fast in low volumes, and CNC prototyping produces parts not too far from production quality. The cost is higher than 3D printing but the surface finish and part strength are often superior.
  • CNC Turning — All types of round components
  • CNC Grinding — Tight tolerance and good surface
  • CNC EDM — For deep pocket & sharp conners

Rapid vacuum casting

Rapid vacuum casting is a low-cost prototyping service for the production of low-cost plastic parts, particularly items like colorful display models. Advantages of rapid vacuum casting include very low tooling costs compared to injection molding and a much lower minimum order quantity. And although vacuum cast parts are not especially durable, they come out of the mold with an excellent surface finish without post-processing. The silicone mold used for rapid vacuum casting typically lasts around 20 shots, ideal for most prototyping scenarios.
  • Rigid Plastics — Such as ABS, PC, PA simulate prototype parts
  • Soft Rubber — Rubber like prototypes from Shore A 30 to 90 degrees.
  • Wax — Patterns for low-vlume investment casting

Rapid sheet metal prototyping

Rapid sheet metal prototyping is a set of rapid prototyping services for the production of sheet metal parts. This includes various forming, cutting, and assembly processes for manipulating the sheet metal stock in different ways. Rapid sheet metal prototyping is generally used for flat parts like brackets and enclosures, and it can accommodate a range of sizes, including very large metal parts. Setup times can be longer than comparable processes, but sheet metal is highly cost-effective when making large and relatively simple parts. An advantage of rapid sheet metal prototyping is that the solid sheet metal feedstock can later be CNC machined for additional features.
  • Cutting
  • Bending
  • Stamping
  • Welding

Rapid Metal Casting

Casting is generally considered a production process for high-quality metal parts, but rapid metal casting — using 3D printing to make low-cost patterns — offers an affordable route for prototyping cast metal. Our rapid metal casting services are only available due to our close relationship with several large casting companies which typically would not accept low-volume (10+) prototyping orders from new customers. Advantages of rapid metal casting include near production-quality metal parts, with potentially very large sizes, at surprisingly fast speeds. Cast parts also have excellent tensile strength and can also be post-machined.
  • Pressure Die Casting
  • Investment Casting
  • Gravity Casting

Rapid Tooling / Mould

Rapid tooling (bridge tooling or prototype tooling) refers to the rapid CNC machining of metal tooling for injection molding. It is therefore the first step toward rapid injection molding. Prototyping tooling for molding is ideal when the customer requires between 100–2,000 units of their injection molded parts; more than this and production-level steel tooling may be preferred. Advantages of rapid tooling include fast turnarounds and the ability to carry out prototyping and testing of injection molded parts that might otherwise take months to produce. Rapid tooling is also significantly cheaper than mass production tooling. Although rapid tooling and rapid injection molding is more expensive than 3D printing, it provides plastic parts much nearer to production quality that can therefore be used for functional testing.
  • Plastic Injection Mold
  • Die Casting Mold
  • Extrusion Mold
  • Silicone Mould

Rapid CNC Machining

Our advanced 3 axis, 4 axis and 5 axis CNC machining help cut your product parts with great precision, ensuring your rapid prototyping runs smoothly while producing as many parts as possible.

Rapid Injection Molding

Our rapid injection molding process results in an identical set of durable parts for testing and multiple backups. This process has a longer lead time, but it is usually worth it, especially for a product with strict material and mechanical requirements.

Rapid Sheet Metal Fabrication

We offer a variety of metals and alloys, including stainless steel, copper and aluminum, for your metal fabrication prototyping. We also have the capacity to fabricate two or more metal prototype designs simultaneously.

Rapid 3D Printing

This is the most common method used for rapid prototyping. This process requires no tooling, making it cost-effective and has a fast lead time. We use different 3D printing methods, including fused deposition model (FDM), selective laser sintering (SLS) and stereolithography (SLA).

Rapid Vacuum Casting

We offer rapid vacuum casting for the manufacturing of low-cost plastic parts. This method of rapid prototyping is similar to injection molding. However, the tooling for this manufacturing is not very durable, making it ideal for low volume production.

Types of rapid prototype

Used by customers across many industries, rapid prototyping encompasses different technologies and materials. It also covers different kinds of prototype, including visual-only prototypes and functional prototypes used for testing a part’s performance.
This is one of the simplest types of prototypes. Also called a proof-of-concept prototype, engineers use the concept model to convey the basic idea of the design. Before use, this type of prototype undergoes multiple changes.
Engineers develop this type of prototype to make it look similar to the final product. Most times, functionality is not a factor considered under the display prototype as the focus is mainly on appearance.
This prototype focuses on functionality and aims to enable engineers and designers to test the product to make modifications if any, for optimal functionality. The prototype developed here should behave the same way as the final product.
This is the last type of prototype developed before production. There are two major purposes of this type of prototype. First, to validate the process chosen by the manufacturer for mass production, and second, to ensure the manufactured part functions optimally.

Precision Machining FAQ

There are a couple of scenarios where rapid prototypes become a need. The first is when the cost of product development becomes too high. Rapid prototyping cost is lower than conventional prototyping, reducing product development costs. Rapid prototypes are also needed when you need to identify and evaluate product hazards as well as test functionality.

There’s a wide range of materials that can be used in precision machining – you can use aluminum brass, copper, steel, titanium, as well as rigid plastics like PPS, PEEK. Reach out to learn more about the types of materials that are available when using precision machining technology.

the fast lead time for rapid prototyping is 5 working days. This is especially true when you use reputable brands that offer rapid prototyping online services for your needs.

Rapid prototyping and 3D printing are completely different from each other. 3D printing is a technology that uses additive manufacturing to develop products. On the other hand, rapid prototyping is an umbrella term for a group of techniques used for the manufacturing of product parts from a 3D CAD model.
Using rapid prototyping technologies requires design software. This software allows you to design a part on a computer, controlling its shape and dimensions and making design adjustments based on the chosen manufacturing technique. However, whether you are able to develop a feasible digital design probably depends on your level of design and engineering experience. Those without prior CAD experience might need to consult a professional product designer to fulfill the design brief. Professionals know how to manipulate the software, and they also know whether a design can realistically be fabricated using hardware like a CNC machine. (We often receive designs that are not manufacturable because they do not take into account factors like draft angles, parting lines and overhangs.) Those who do have CAD experience — product designers, R&D specialists, etc. — can create a digital design using their design suite of choice then export it to a machine-readable format such as a STEP file (for CNC machining, etc.) or a Mesh file (for 3D printing etc.). The digital file is the most important stage, but you must also specify a desired material, quantity and surface finish (if required) to the rapid prototyping company. In many cases, you might prefer to send off Requests for Quotation (RFQs) to several rapid prototyping companies in order to compare quotations in terms of price, proposed lead time and the reputation of the manufacturer. Once a satisfactory quotation has been received, you can finalize the order with the rapid prototyping company, who will use your digital design and order specifications to commence production. The prototypes will be shipped to you once production is complete.
Rapid prototyping is a fast way to verify the aspect and function of your design. Prototypes are also widely used for business proposals, where they can be shown to potential investors and customers.
Most rapid prototyping projects can be completed in a matter of days, and we offer fast global delivery. If you require a precise lead time, please submit your project to get a free quotation and lead time information at the same time.
