Why does TC Precision use green-light lasers for copper 3D printing?

Pure copper reflects most of the 1064 nm infrared energy used by standard fiber lasers, which leads to unstable melt pools and porosity. A green laser (around 515 nm) is absorbed far more efficiently, producing denser copper parts for heat exchangers, induction coils and electrical conductors.

What tolerances can you hold on CNC machined and 3D printed metal parts?

Unless otherwise specified, machined features follow ISO 2768-m. Critical CNC-finished features can reach ±0.005 mm depending on geometry, material and part size. As-printed metal surfaces are typically ±0.1–0.2 mm, so we machine critical interfaces such as bores, sealing faces and datums after printing.

Is there a minimum order quantity?

No. We support single prototypes, engineering validation batches and low- to mid-volume production runs, and recommend the most economical process for each quantity during DFM review.

Which files should I send for a DFM review?

Please send a 3D model (STEP, IGES, X_T or STL for printing), a 2D PDF drawing with tolerances and GD&T, the material grade, surface finish, quantity and target delivery date. An NDA can be signed before files are shared.

How are parts inspected and shipped to overseas buyers?

Every order is dimensionally inspected against your drawing, and inspection reports and material certificates can be supplied on request. Parts are packed for export and shipped by international express courier, air freight or sea freight to customers worldwide.

Technical & Commercial FAQ

Frequently Asked Questions by Danish Procurement Directors

Clear, direct answers regarding metallurgical certification, pricing structures, shipping guarantees, and intellectual property safety.

How can an overseas manufacturer offer lower pricing than local Danish suppliers without sacrificing quality?

Our pricing edge stems from ecosystem concentration in Dongguan and process optimization rather than compromised materials. We consolidate selective laser melting and 5-axis secondary operations under one roof, cutting out markup overhead from multiple subcontractors. Furthermore, our raw metal powder purchasing volumes and high-utilization automated cells dramatically reduce the machine-hour cost compared to typical Danish contract machine shops.

What documentation and inspection protocols are supplied for industrial parts entering Denmark?

Every shipment includes a comprehensive QA package: EN 10204 3.1 material chemical & mechanical test certificates, full coordinate measuring machine (CMM) dimensional verification reports, surface roughness (Ra) profiles, and heat treatment charts. Non-destructive testing (X-ray CT scanning for internal lattice structures or dye penetrant testing) is available upon request for critical components.

Why is Green-Laser 3D printing essential for pure copper components in wind and EV drive systems?

Standard infrared fiber lasers (1064 nm) encounter over 90% optical reflection when interacting with pure copper powder, risking machine damage, severe spatter, and porous parts below 95% density. Our 515 nm green laser system operates at the optical absorption peak of pure copper, achieving consistent densities above 99.8% and electrical conductivity exceeding 100% IACS, vital for Danish renewable power electronics and induction heating manifolds.

How do you protect intellectual property (IP) and CAD designs sent from Denmark?

We operate under strict bilateral Non-Disclosure Agreements (NDAs) subject to Danish and international trade law. Internally, customer engineering data is isolated within encrypted servers accessible exclusively by designated CAM and DFM project engineers. Production files are wiped following order completion, and we never display custom components publicly without explicit customer sign-off.

What are the standard freight transit timelines from Dongguan to Denmark?

For urgent prototypes and small pre-series batches, air courier shipments via DHL/FedEx Express arrive in Denmark (Copenhagen, Billund, or Aalborg) within 3 to 5 business days, including expedited customs clearance. For scheduled low-volume production orders, combined air freight or consolidated maritime shipping is utilized to balance logistics expenditure with delivery predictability.
