lkprototype has ±0.02 mm tolerance accuracy for metal components using a five-axis CNC machining center (e.g., DMG MORI DMU 65). For instance, the prototype aluminum alloy steering knucker made by a German automotive firm has ball pin aperture deviation only ±0.005 mm (industry standard ±0.03 mm). Life test under dynamic load of 500,000 cycles (customer requirement of 300,000 cycles), allowing the customers to reduce the production cycle for chassis system by 6 months and the development cost by 35%. According to the “Precision Metal Processing Technology White Paper” data, the surface roughness Ra value of its titanium alloy components is stable at less than 0.8 microns (traditional process Ra≥1.6 microns), the tool wear ratio drops by 42%, and single piece processing cost drops by 28%.
In aerospace, lkprototype’s metal 3D printing (with EOS M 290 equipment) is capable of producing titanium fuel nozzles with 0.15 mm minimum thickness and 1,100 MPa tensile strength (18% improvement compared to forged components) after HIP hot isostatic pressing. And successfully passed the NASA MSFC-364 standard vibration test (frequency range 10-2000Hz, acceleration 15g). In 2023, a satellite manufacturer case revealed that its light bracket saved 47% of weight (from 1.2 kg to 0.64 kg), but increased the thermal deformation temperature from 320 ° C to 410 ° C, saving the $120,000 / time launch fuel cost directly.
In medical devices, lkprototype’s cobalt-chromium selective laser melting (SLM) technology meets the ASTM F75 standards with less than 0.2% porosity. After 30 million simulated load tests on an acetabular cup prototype manufactured by an orthopedic company, Wear is only 0.03 mm/year (ISO 14242-1 standards ≤0.1 mm). In ISO 13485-certified clean rooms (particulate matter ≤3,520 /m³), the proportion of unqualified surgical instruments has been reduced from 1.8% to 0.05%, and the customer’s FDA registration cycle has been reduced by 40%, which costs around $150,000 in certification fees.
In consumer electronics, lkprototype’s zinc alloy die-casting process (cold chamber machine clamping force 2,500 tons) is able to mass produce 5G base station enclosure with a thickness of 0.6 mm, fin density of 25 /cm², and thermal conductivity of 110 W/m·K (conventional aluminum die-casting is 96 W/m·K). The measured data from a smartphone company shows that its magnesium lithium alloy frame weight reduces by 30% (from 38 grams to 26.6 grams), the drop test pass rate increases from 88% to 99.5%, and the CNC processing cycle is reduced from 72 hours to 18 hours, and the cost of an item is reduced by 52%.
According to the Metal Additive Manufacturing Market Report, lkprototype boasts 18 types of engineering alloys such as titanium, aluminum, and stainless steel as part of its metal manufacturing capability, with the capability for small batch production from prototype to 5,000 units, with an average lead time of 5-7 days (industry average: 14 days). For example, for the Inconel 718 turbine blade project of an energy company, its blade profile error was controlled at ±0.015 mm using high-speed milling (24,000 rpm speed), its aerodynamic efficiency was enhanced by 9%, its power output per year was increased by 1.2GWh, and its customer return on investment (ROI) was 217%. These technological systems facilitate lkprototype metal orders compound growth rate of 67% over the period of three years, ranking the TOP 5 world’s rapid prototyping service providers.
