What is Curta Calculator Reproduction?
A curta calculator reproduction is a modern attempt to recreate the “Type I” or “Type II” mechanical Curta calculators originally designed by Curt Herzstark. These devices are masterpieces of mechanical engineering, containing over 600 precision parts.
Reproducing these today involves high-fidelity manufacturing techniques such as SLS 3D printing, CNC machining, and manual assembly. Because of the extreme precision required, the financial feasibility depends heavily on balancing high fixed setup costs against the unit sales price.
How to Calculate Curta Calculator Reproduction (Example)
- Identify your Fixed Costs: Suppose R&D and tooling cost $20,000.
- Determine Variable Costs: High-grade steel and assembly cost $300 per unit.
- Set a Selling Price: You plan to sell each unit for $800.
- Subtract Variable Cost from Price: $800 – $300 = $500 (Contribution Margin).
- Divide Fixed Cost by Margin: $20,000 / $500 = 40 units. You must sell 40 units to break even.
Frequently Asked Questions (FAQ)
Is it legal to create a Curta calculator reproduction? Yes, as the original patents have expired. However, using the “Curta” brand name may require trademark verification.
What is the biggest cost in reproduction? Usually the precision tooling for the internal stepped drum and the assembly labor involved in timing the gears.
Can I use 3D printing for the parts? While possible, standard FDM printing lacks the resolution. Resin or SLS printing is required for functional gears.
How many units make a project viable? Most enthusiasts find that small batches of 50-100 units help amortize the high cost of engineering.
