In today’s fast-paced, fiercely competitive world of product innovation and product development, there is a greater need for rapid prototyping solutions. Rapid prototyping solutions allows for speedy testing, quick adjustments to be made and helps speed up the overall manufacturing process and time to market.

While there are a selection of processes, in this blog, we have picked several mature and well-established processes to help you with your search for high-quality rapid prototyping solutions. They include:

SLA 3D Printing

Stereolithography (SLA) 3D printing offers one of the widest ranges of material options. It builds parts one layer at a time using a highly accurate UV laser to solidify one layer of photosensitive resin making the parts accurate and allowing it to achieve a high-quality surface finish through the 3D building process itself. This makes it an excellent choice for aesthetic prototypes and highly detailed parts requiring tight tolerances.

If you need your part to look and feel like the real thing for concept presentations, tradeshows, or photographic purposes, SLA is our recommended rapid prototyping solution.

SLA

SLA prototype parts may, however, not be as strong as those made from engineering-grade resins. That’s why SLS printing is recommended for functional testing.

SLS 3D Printing

Selective Laser Sintering (SLS) builds accurate and durable parts (often from nylon materials) one layer at a time. Similar to SLA, with SLS printing, geometries can be built more easily due to the 3D printing process, adding complexity without additional cost. The combination of low cost per part, established materials, and its speed makes SLS printing a go-to solution among engineers for functional prototyping.

SLS

As mentioned, with SLS, there are very limited material selection. If your functional prototyping project is particular on material type, consider using CNC machining for these parts.

CNC Machining

When thinking of rapid prototyping solutions, 3D printing often first comes to mind; however, many aren’t aware that CNC machining is an ideal one-off prototyping method for the right projects. It’s fast, dimensionally accurate and very versatile as it can accommodate for almost any solid material. This makes it the perfect solution for strong mechanical parts that need to be fully functional and have precise tolerances – basically, full-production quality but in a limited number.

CNC Machining

This method is, however, not ideal for deep cavities and thin-walled parts. Consider using vacuum casting as a rapid prototyping solution for these parts.

Vacuum Casting

Vacuum casting or cast urethanes is a perfect solution for production quality parts without the cost or lead time required for prototype tooling. For injection molng projects, X-PRO recommends using vacuum casting prototyping solutions. It produces parts with similar properties but cheaper and quicker. This prototyping solution allows for a faster turnaround time that helps speed up product development and time to market, which is a prioritized KPI for many industries.
