Due to the additive nature of the process, 3D printing allows for higher freedom of design than traditional manufacturing methods. To take full advantage of the technologies available at HLH, design your 3D model for the process.

Yes, it’s possible. Selective Laser Melting (SLM) and Direct Metal Laser Sintering (DMLS) machines, like the ones we use at HLH, are designed for 3D printing high-quality, precision metal parts. These technologies can build parts from a wide range of metal alloys, including aluminium, stainless steel, copper, bronze, titanium, and nickel-based superalloys.
While PLA and PETG are often certified as food-grade materials, we do not recommend 3D printing for food containers or other food-safe applications. Even with certified filaments, the printing process and post-processing can introduce risks—such as contamination from printer nozzles, chemical degradation due to high extrusion temperatures, and potential chemical interactions—making printed parts unsafe for direct food contact.
In manufacturing you’re only as good as your last order, so we take quality seriously.
Once completed, your 3D printed parts are transferred to the quality control (QC) department for inspection. We include a comprehensive, standardized inspection report with every order to ensure quality metrics are being met. We also have multiple certifications available on request, including ISO 9001, ISO 14001, ISO 27001, ISO 13485 and IATF 16949.
The unit price of 3D printing can range from just $1.20 to several hundred, depending on factors such as material, print time, part weight, printer type and design complexity. Metal 3D printing is generally more expensive due to the higher material cost, specialized machinery, and the longer, more labor-intensive post-processing it requires.
