3D Printing Technical Specifications
1. Maximum build size of the metal 3D printer: 250 x 250 x 325 mm;
2. 3D printing layer thickness: 0.02 mm – 0.04 mm;
3. Achievable 3D printing accuracy: typical accuracy ±0.02–0.05 mm (accuracy depends on geometry and varies with part size, build orientation, material and post-processing method);
4. Post-processing: high-temperature annealing, polishing, welding and other processing;
MS1 Mold Steel 3D Printing Material Properties
The 3D printing metal powder mold steel MS1 has a chemical composition corresponding to US classification 18% Ni Maraging 300, European 1.2709 and German X3NiCoMoTi 18-9-5. This steel is characterized by very good mechanical properties and is easily heat-treated. A simple thermal age-hardening treatment is used to obtain excellent hardness and strength.
3D-printed molds are mainly used for conformal cooling channels, molds with profiled cooling channel inserts, and sliders, with typical applications in precision injection molds and die-casting mold manufacturing. They offer clear, practical advantages:
1. Greatly reduce manufacturing costs by aligning the mold design cycle with the product design cycle, cutting time and material consumption and thereby improving overall production efficiency;
2. Effectively reduce residual stress, prevent product warpage and deformation, and ensure dimensional accuracy;
3. A defining feature of 3D printing is that there are no shape constraints, even for complex internal features and channels — in other words, conformal cooling channels in a mold can be designed in any shape,
greatly reducing cooling time;
4. Compared with traditional mold manufacturing, 3D-printed molds have a longer service life (millions of shots) and higher production efficiency (production cycles shortened by 30%–70%);
