Modern Metal Printing Technology

From complex prototypes to serial parts — precision, strength, and design freedom

  • High Density and Precision

    Laser Powder Melting (SLM) provides up to 99.5% material density and mechanical properties comparable to traditional manufacturing. With printing accuracy up to 70 microns, it’s ideal for creating complex geometries without loss of quality.

  • Faster Production Cycles

    Conformal cooling makes it possible to 3D print metal molds or inserts with internal channels that evenly dissipate heat. This reduces the molding cycle time, minimizes defects, and improves the quality of finished products. For small-sized molds, 3D printing can be a faster and more cost-effective alternative to ordering a traditional one.

  • Melting Temperature: ~1370 °C

Frequently Asked Questions

  • How does 3D metal printing differ from traditional casting or machining?

    Traditional methods require molds, tooling, and multi-step processing. 3D metal printing allows you to create parts directly from a CAD model, significantly reducing time and costs.

  • What is the maximum size of parts that can be printed?

    Our Xact Metal XM200G printer has a build volume of 150 × 150 × 150 mm, enabling the printing of both small high-precision components and medium-sized functional parts.

  • How accurate are the finished parts?

    Part accuracy reaches tens of microns thanks to a laser beam diameter of 50–100 μm, ensuring a smooth surface and minimal need for secondary processing.

  • Is post-processing required for printed parts?

    Yes, depending on surface and mechanical requirements, processes such as polishing, heat treatment, milling, or grinding can be applied. This achieves final quality comparable to traditional products.

  • How long does it take to estimate the cost of metal printing?

    The time required to assess the cost and feasibility of metal printing depends on multiple factors — not only the weight (volume) of the part, but also its geometry, post-processing complexity, and other technological parameters. These aspects affect the choice of technology, printing duration, and the extent of finishing work. Therefore, the estimation process may take longer than the usual 30–60 minutes — sometimes several hours or up to two working days. Additionally, since the production facility is located outside Ukraine, all logistics considerations must be taken into account.

        *The assessment of the cost and feasibility of metal printing is based on several factors — not only the weight (volume) of the part, but also its geometry, the complexity of post-processing, and other technological parameters. Therefore, the preparation of the estimate may take longer than the usual 30–60 minutes, extending to several hours or even up to two working days. In addition, since the production facility is located outside Ukraine, it is important to consider all relevant logistics factors.
