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.
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.
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.
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.
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.
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.
3ERP’s 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.
In simpler terms, you use technology to transform a product idea into a physical model. This early physical model is a prototype. You’ll then refine this until you get the final version right. At that point, you’re ready to use or sell this into a product. So the faster you produce and refine your prototypes, the faster you can start going to market.
All rapid prototyping jobs begin with digital models, but manufacturing hardware can range between CNC machining, 3D printing, and more.
You can make rapid prototypes from any material that’s compatible with the manufacturing hardware that you use. This might or might not include surface finishing treatments.
As its name implies, rapid prototyping puts an emphasis on fast turnarounds. Because when you want to develop and ship a product using rapid prototyping services, faster is always better.
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.
