METAL ADDITIVE MANUFACTURING MATERIALS.
Rennscot MFG is an additive manufacturer ready to support everything from prototypes to critical programs at scale. We print in four proven metals, so you can match the material to the job. AlSi10Mg is a lightweight aluminum alloy with good strength and excellent heat conduction, which makes it suitable for housings, brackets, and heat exchangers. 316 stainless steel is tough and highly corrosion resistant, a good fit for fluid handling, tooling, and parts that face harsh environments. Titanium offers one of the best strength to weight ratios available and stands up to corrosion, which makes it the superior choice in aerospace and demanding structural parts. For extreme heat and stress, Inconel holds its strength at temperatures where other metals give out, which suits engine components, thermal hardware, and high-performance applications. Not sure which one is right for your part? Our engineers can help you choose.
ADDITIVE MATERIALS
AlSi10Mg
AlSi10Mg is a lightweight aluminum alloy that combines strength with thermal conductivity. This makes it a great choice for housings, brackets, and heat exchangers where saving weight and moving heat both matter. It’s also one of the most proven aluminum alloys for metal 3D printing. It’s a reliable, cost-effective option for both prototypes and production parts.
316 Stainless Steel
316 stainless steel is a tough, highly corrosion-resistant alloy that holds up in harsh environments, including exposure to moisture, chemicals, and saltwater. This makes it a strong fit for fluid handling components, tooling, and parts that require long-term durability. Printing in 316SS allows for complex shapes like internal channels and consolidated assemblies that would be difficult to machine from solid stock.
Ti64
Ti64 is a titanium alloy with one of the best strength-to-weight ratios of any metal, with excellent corrosion resistance and strong performance at elevated temperatures. Ti64 is the optimal choice for aerospace structures, defense hardware, and other parts where every gram matters. Printing allows for lightweight, optimized geometries and complex internal features while avoiding the high material waste of machining titanium from solid billet.
Inconel
Inconel is a nickel-based superalloy built for extreme conditions, holding its strength and resisting oxidation and corrosion at temperatures where most metals give out. That makes it a top choice for rocket and jet engine components, heat exchangers, and other high-temperature hardware. Printing it allows us to create complex shapes and internal cooling channels that are very difficult to machine, since Inconel is notoriously difficult to cut from solid stock. Common alloys include IN-718 and IN-625.
OUR ADDITIVE FACILITY
In 2025 we made a significant investment in our metal additive manufacturing facility located directly next door to our existing headquarters and machine shop.
+ Built for scale; the facility will hold 12+ medium format printers.
+ We also created a dedicated powder storage room and metallurgical lab.
+ The whole facility is laid with ESD safe flooring and conditioned with precise climate control for both temperature and humidity.
FREQUENT
QUESTIONS
What materials can you 3D print?
We print in four metals: aluminum (AlSi10Mg), 316 stainless steel, titanium (Ti6Al4V), and Inconel. Each one suits different needs for weight, strength, corrosion resistance, and temperature.
How do I choose the right material for my part?
It depends on your operating environment and priorities. AlSi10Mg is best for lightweight parts and heat transfer, 316SS for corrosion resistance and durability, Ti64 for strength-to-weight, and Inconel for extreme heat. Our engineers can help you choose.
Can you machine 3D printed parts after they’re built?
Yes. We handle post-processing in-house, including heat treatment, surface finishing, and CNC machining of critical features to your final tolerances, so printed parts arrive ready to use.
