EV Powertrain & Structural Castings
Precision EV castings delivered in days — not months — with zero tooling investment.
We produce electric vehicle components for battery electric vehicles (BEVs), hybrid electric vehicles (HEVs), fuel cell electric vehicles, and electric drive vehicles using our patented LAMP™ ceramic 3D printing technology — delivering first parts in as little as 10 days at 50% lower cost, with no dies, patterns, or tooling required. Our process creates critical electric traction motor housings, battery packs, motor controllers, power electronics, and auxiliary systems optimized for converting electrical energy into mechanical energy and supporting safe, efficient operation.
Benefits of Electric Vehicle Component Manufacturing
Zero Tooling Investment for EV Component Development
Traditional EV component manufacturing demands $100,000+ in upfront tooling before a single part is made. LAMP™ eliminates that barrier:
90% Energy Reduction in EV Component Production
Our ARPA-E-validated process reduces energy consumption by up to 90% versus traditional investment casting — eliminating seven of twelve energy-intensive process steps:
Complex Integrated Geometries for Advanced EV Systems
Conventional tooling cannot produce the internal geometries modern EV powertrain components demand. Our LAMP™ process integrates all internal features into a single printed ceramic shell:
Industry Applications
EV Powertrain Components
The basic EV powertrain — typically composed of the battery pack, electric traction motor, power electronics controller, and thermal management systems — contains relatively few components compared to internal combustion engine vehicles. Each of those components, however, demands exceptional precision, a proper operating temperature range, and energy efficiency. Our LAMP™ technology produces critical electric traction motor housings, motor controller enclosures, battery management system housings, inverter cooling systems, auxiliary batteries, and onboard chargers — all in a single casting operation that traditional investment casting cannot match.
Lightweight Structural Castings
Lightweighting is the single most important strategy for extending an electric vehicle’s range — every gram saved in the vehicle’s chassis, closures, and body-in-white allows for a smaller traction battery or longer driving range. Our ceramic 3D printing process enables topology-optimized structural castings with integrated features, eliminating the weight penalties of welded assemblies and multi-piece fabrications. From suspension components to battery enclosure structures, we produce EV structural castings, essential components, and vehicle accessories that support next-generation electric cars and fully electric vehicles while maintaining efficient operation.

Digital Model Optimization for EV Applications
Every EV component begins with a comprehensive digital analysis optimizing thermal systems, weight, energy efficiency, and battery pack performance. Our engineering team integrates cooling channels, mounting features, mechanical system components, and structural elements into a single printable ceramic shell — eliminating multi-piece tooling chains that delay EV development programs by months.
LAMP™ Ceramic Shell 3D Printing for EV Components
Our proprietary Large Area Maskless Photopolymerization (LAMP™) technology prints ceramic investment casting shells directly from digital files — no wax patterns, no core assembly, no traditional shell-building delays. 3D printing enables the production of complex shapes that replace larger assemblies like heat exchangers, battery housings, and motor enclosures, improving performance while reducing mechanical system complexity. Build volumes up to 24″ × 24″ × 24″ to accommodate production-scale EV components with surface finishes under 4 microns RMS and ±2-micron positioning accuracy.
Precision Casting and Quality Assurance
Printed ceramic shells are thermally processed and sintered to over 99.5% density before pouring aluminum alloys, stainless steels, and specialized materials optimized for battery electric vehicles, hybrid electric vehicles, and electric drive vehicles. Complete dimensional inspection, nondestructive testing, and verification of thermal system performance guarantee safe, efficient, and reliable operation before delivery to EV assembly lines. Electrical power, AC electricity, DC electricity, and voltage distribution are verified for proper functioning with auxiliary systems and power vehicle accessories.

Frequently Asked Questions About Electric Vehicle Components
The seven essential parts of an electric motor are the stator, rotor, commutator, brushes, axle, field magnet, and DC power supply. Brushless motor designs replace mechanical commutators with electronic controllers. LAMP™ technology produces motor housings, cooling channels, traction battery enclosures, and auxiliary battery systems optimized for safe, efficient, and high-performance motor operation, converting electrical energy into mechanical energy for smooth acceleration, rotation, and torque delivery to the wheels.
The battery pack, typically composed of lithium-ion batteries and traction batteries, stores electrical energy and powers onboard chargers, charging ports, and external power sources. It is the most expensive component, accounting for 30–40% of vehicle cost. Electric traction motors, power electronics controllers, and thermal management systems also significantly contribute. Proper thermal management, DC voltage distribution, and efficient power electronics support optimal performance, fuel economy, range, and longevity.
