When you’re finishing the design stage of product creation and the product needs to get to market fast, you’re likely considering rapid prototyping. Rapid prototyping uses turnkey fabrication technologies such as 3D printing and CNC machining to produce prototypes quickly and avoid the costs and bottlenecks of a complex product development process. This allows you to test a design’s fit, form, and function early and often so you can make necessary adjustments to the design and materials before the actual manufacturing process.
Rapid prototyping is all about speed and affordability. When you can get the right rapid prototyping materials for a low price from a fast, reliable source, you can work through multiple iterations of a design quickly or even prototype multiple designs at once.
Sourcing the right material is an important step in the prototyping process. Sophisticated concept models sometimes require materials with specific strength profiles, thermal or electrical conductivity, temperature resistance, or other special properties beyond those of widely available steel and aluminum. If you need unusual materials for rapid prototyping such as titanium or nickel-based superalloys, a local metal recycler can provide options such as verified metal remnants to meet your needs for affordable prices.
Exotic Metals for the Rapid Prototyping Process
Steel is cheap and strong, and aluminum is an incredibly versatile material, but some prototypes have specifications that these common metals just can’t meet. Whether you need extra strength, temperature resistance, conductivity, or any other special property, there are other options for rapid prototyping materials that can create functional prototypes.
Titanium and its alloys, for example, are often used for components that need to be strong while minimizing weight, such as aerospace and automotive parts. When steel is too heavy, and aluminum isn’t strong enough, titanium may be the right choice for producing functional prototypes. Titanium is also biocompatible, so it’s common in surgical equipment and implanted medical devices.
What if your prototype needs to be able to handle extreme conditions? Nickel-based superalloys like Monel, Hastelloy, and Invar have outstanding corrosion and temperature resistance, making these specialty metals good rapid prototyping materials for parts that will be exposed to corrosive fluids or extremely high temperatures.
Industrial Metal Service carries a wide variety of ferrous and nonferrous metal stock and offers quick and convenient delivery to manufacturers, fabricators, and machine shops in the San Francisco Bay Area and nationwide. Our inventory includes verified exotic and unusual metals such as:
- Commercially Pure Titanium
- Titanium 6-4

The table below provides a quick reference to the key characteristics and common applications of various exotic metals used in rapid prototyping, along with an estimate of their cost.
| Metal Type | Density (g/cm³) | Tensile Strength (MPa) | Corrosion Resistance | Thermal Conductivity (W/mK) | Common Uses in Prototyping | Cost Estimate |
| Titanium | 4.5 | 900 – 1,200 | High | 22 | Aerospace, Medical Devices | High |
| Aluminum | 2.7 | 110 – 700 | Moderate | 205 | Automotive, Consumer Electronics | Moderate |
| Stainless Steel | 7.9 | 500 – 2,000 | High | 15 | Surgical Instruments, Industrial | Moderate to High |
| Nickel Alloy | 8.9 | 1,000 – 1,400 | Very High | 11 | High-Temperature Environments | Very High |
Verified Metal Remnants
Usually, the downside of working with exotic materials for rapid prototyping, such as titanium or superalloys, is the price. However, there’s an alternative to high mill prices. Many San Francisco Bay Area machine shops have found that verified metal remnants are excellent with rapid prototyping technology, and they’re often available at much lower prices than new metal sourced directly from the mill.
These remnants, though not useful to the manufacturer, are ideal for product designers, machine shops, and fabricators that don’t require new, direct-from-the-mill alloys to meet specifications. Local metal recyclers such as Industrial Metal Service specialize in recycling these usable metal remnants and providing them to customers as an affordable option for rapid prototypes.
Industrial Metal Service uses x-ray fluorescence technology to verify the chemical composition of our metal remnants, so you can be confident in the type and grade of metal you’re getting.

Applications Across Diverse Industries
Rapid prototyping processes have revolutionized how industries approach product development and testing, whether using additive manufacturing or traditional manufacturing methods. One of the most common rapid prototyping techniques involves using exotic metals and other materials to create multiple prototypes that mimic the final product’s functionality and design. This method is pivotal in industries such as aerospace, where precision, mechanical properties, and material characteristics of components are critical.
Automotive sectors benefit as well, as they rely on rapid prototyping services to innovate and improve vehicle design efficiently. In healthcare, rapid prototyping is used to produce patient-specific medical devices with complex geometries, offering bespoke solutions that were unimaginable a few years ago.
Consumer electronics also leverage these techniques to develop and refine gadgets rapidly, ensuring they meet aesthetic and functional standards while sporting complex designs. These diverse applications underscore the versatility and importance of the rapid prototyping process in modern manufacturing.

Innovations and Emerging Trends
The field of rapid prototyping is continuously evolving, with new materials and rapid manufacturing processes emerging regularly. Recent innovations have expanded the capabilities of rapid prototyping services, allowing for more complex and diverse applications.
Multi-material printing, a significant advancement in this domain, enables the integration of different materials in a single print, enhancing the functional and aesthetic qualities of prototypes in the iterative process. Additionally, the development of nanocomposites in the rapid prototyping service sector has introduced materials with improved strength and conductivity, which are crucial in demanding industries such as aerospace and electronics.
Another trend is the growing focus on biocompatible materials in healthcare, facilitating the creation of medical implants and devices that are safe for human use. Lastly, the push towards sustainable materials in rapid prototyping reflects a growing commitment to environmental responsibility, making rapid prototyping processes innovative and eco-friendly, even for mass production.
