Case Study: PTZ-Prototypenzentrum GmbH achieves 28% faster cooling and saves 111 hours/year with Markforged Copper (Metal X)
A Markforged Case Study
PTZ-Prototypenzentrum GmbH - Customer Case Study
PTZ-Prototypenzentrum GmbH, a Dresden-based prototyping specialist working in metal and plastic for over 20 years, faced a persistent challenge with a thermally actuated tool cooler: machined aluminum lacked the conductivity to meet desired cycle times, and a selective laser melted AlSi10Mg redesign improved cooling but failed against the cooling medium and was costly to produce. The team solved the manufacturing constraint by moving to metal printing on the Markforged Metal X platform and exploring new materials.
Markforged supplied a Markforged Copper solution with conformal cooling channels that were impossible to make conventionally; the copper cooler resisted the cooling medium and delivered 28% faster cooling. By eliminating roughly 40 tool changes per day across two CNC machines, PTZ-Prototypenzentrum GmbH saves about 111 hours per year—approximately $6,993 annually in machine time—making Markforged the cost-effective, high-performance choice.
