About the maker
I'm Nick Lindenmuth, and LindenTech is my one-person design and fabrication shop in Alta, California, in the Sierra Nevada foothills.
I take projects from idea to finished part: CAD design, 3D-printed prototypes and patterns, investment and ceramic shell casting in aluminum and bronze, and mechatronics work including circuit board and low-voltage electrical design. Because everything happens in one shop, nothing gets lost in translation between designer, printer, and foundry — I'm all three.
Most of my work is one-offs and short runs for people who need a real metal part or a working prototype: replacement parts that don't exist anymore, custom brackets and hardware, art castings, and electromechanical projects that need both the enclosure and the electronics inside it.
How pricing works
I bill design and fabrication time hourly, plus materials. Every project starts with a conversation and a quote — no surprises.

I only cast non-ferrous metals.

Services
Investment (Lost Wax) Casting — Best for small, detailed pieces. Your 3D file is printed in wax, encased in plaster, and melted out. Metal is poured with vacuum assistance to capture fine detail. It won't match the flawless finish of CNC or die casting, but it offers unmatched flexibility for one-offs and complex shapes.
Ceramic Shell Casting — Ideal for larger pieces. A ceramic shell is built up around the wax pattern over about a week. Slower, but the right choice for big or heavy castings.
Resin 3D Printing — High-resolution printing for casting patterns, prototypes, and finished plastic parts. Want to test fit and function before committing to metal? I'll print your part in plastic first.
Mechatronics & Electrical Design — Circuit board design, low-voltage electrical systems, and electromechanical prototyping. If your project needs brains as well as metal, I can design both.
I also have access to SLM 3D printing in stainless steel at pricing comparable to casting — ask if that fits your project.
Note: After casting, I perform basic cleanup. Final sanding and polishing is left to you for a custom finish.
Pricing
3D CAD Design: $75–150/hr depending on complexity.
Casting: $65/hr, varying with size and quantity — bulk orders are more cost-effective.
For accurate quotes, send a 3D file in STL, STP, OBJ, or 3MF format. A drawing or schematic helps if you need design work.
Payment & Policies
Deposit: Custom projects require a 50% deposit to begin, covering materials and setup. The balance is due on completion.
Casting guarantee: If a casting fails due to something on my end, I remake it at no charge until it meets my standards. For designs that push the limits of the process, I'll flag the risks upfront, and if multiple remakes are needed we'll review the design together.
Cancellations: If you cancel after work has started, completed work is deducted from your deposit and the remainder refunded. If I can't deliver a quality casting due to technical challenges, I'll issue a partial or full refund depending on the situation.
