FAQs - Evology Manufacturing

Q: Is Cold Spray Additive Manufacturing environmentally sustainable?

Yes — and not just in the “slap a leaf on it” way. Cold spray technology is a green alternative to traditional metal manufacturing due to: Near-zero material waste (only what's deposited gets used) No toxic fumes or emissions No need for inert gas environments or high-energy lasers Extends the lifecycle of parts through efficient remanufacturing Reduced reliance on overseas supply chains for spares and repairs If you’re trying to make your manufacturing operations more sustainable , cold spray is more than just buzzword-compliant—it’s actually effective.

Q: What materials can be used in Cold Spray Additive Manufacturing?

Cold spray is compatible with a wide variety of metal powders and metal blends , including: Titanium and Ti-6Al-4V Aluminum alloys (e.g., 6061, 7075) Nickel-based alloys (Inconel 625, 718) Copper, silver, and precious metals Steel and stainless steel Tantalum, tungsten, and other refractory metals Composite blends and certain ceramics Because the process doesn’t melt the material, it’s especially suited for difficult-to-form or thermally sensitive metals .

Q: Can Cold Spray Additive Manufacturing be used for repairing damaged or worn metal parts?

Absolutely. In fact, cold spray is one of the most effective technologies for remanufacturing and metal part repair . It can: Rebuild worn or eroded surfaces without thermal stress Restore original geometry and mechanical function Add wear-resistant or corrosion-resistant layers Avoid warping and microstructural damage caused by welding or thermal repair methods This makes cold spray ideal for maintenance of legacy equipment and cost-effective remanufacturing .

Q: What industries use Cold Spray Additive Manufacturing?

Cold Spray is rapidly gaining traction in aerospace , defense , automotive , energy , and medical manufacturing due to its unique ability to produce large, durable, and precise metal parts without the drawbacks of heat-based manufacturing. It’s commonly used for: Ballistic protection and armor plating Aircraft and satellite component repair Corrosion-resistant coatings for oil & gas parts Biocompatible implant coatings Rapid tooling and large cylindrical structures

Q: What are the benefits of using Cold Spray for metal part production and repair?

Cold spray technology offers a range of benefits for metal part manufacturing and restoration , including: No thermal distortion or residual stress , due to the absence of melting. Faster build speeds (up to 6 kg/hr) for large-scale or high-volume applications. Superior material properties like high density, tensile strength, and corrosion resistance. Ability to fuse dissimilar metals in a single component (e.g., steel-titanium hybrids). Eco-friendly : lower emissions, minimal material waste, and no toxic byproducts. Ideal for repair : Extend part lifespan by restoring worn surfaces without disassembly or heat damage.

Q: What Automotive Brands Use Additive Manufacturing?

More than you think. Top brands embracing 3D printing in automotive manufacturing include: Ford – One of the earliest adopters; uses it for both prototyping and production tooling Porsche – Printing high-performance engine components and custom parts BMW – Uses additive for end-use parts in production vehicles Volkswagen – Integrating 3D printing for production-ready components GM – Uses additive across prototyping, tooling, and part validation Bugatti – Famous for 3D-printed titanium brake calipers Koenigsegg – Leveraging metal AM for ultralight hypercar parts Evology works with automotive suppliers and specialty manufacturers to bring the same advanced tech into custom builds, R&D projects, and aftermarket performance applications.

Q: Can 3D Printing Be Used to Make Engine Parts?

Yep— and it already is . One of the most famous examples comes from Porsche , who 3D-printed pistons for the 911 GT2 RS using laser metal fusion (a form of metal additive manufacturing). The result? Lighter pistons with optimized geometry that couldn’t be manufactured using traditional methods. They ran cooler, performed better, and gave Porsche an edge on the track. At Evology, this same type of metal additive process—like DMLS —is available for clients building engine prototypes , thermal management components, and custom brackets, all with aerospace-grade accuracy.
