Industrial-grade wax mold 3D printers are based onSelective laser sintering (<\/strong>SLS<\/strong>) Technology<\/strong>It is an industrial machine for the production of high-precision wax molds made of casting wax powder \/ wax-like powder, which are fused layer by layer and can be used directly for lost wax investment casting. It has significant advantages over the traditional wax molding process and is especially suitable for large casting scenarios (part sizes above 500 mm):<\/p>\n\n\n\n

The 4 core benefits of industrial-grade wax mold 3D printers for foundries (solving industry pain points)<\/h2>\n\n\n\n

1. Reduced cycle time 80% for fast response to order requirements<\/h3>\n\n\n\n

It takes 3 weeks to make a wax mold of a large automotive engine block using traditional processes, but an industrial-grade 3D printer can do it in just 3 days. An aerospace foundry used LaserCore-5300 to print a wax model of a turbine blade, from design to finished product in 48 hours, shortening 80% compared with the traditional process, and compressing the trial production cycle of a new product from 3 months to 1 month, thus seizing the first opportunity in the market.<\/p>\n\n\n\n

2. 5 times higher accuracy and lower casting scrap rate<\/h3>\n\n\n\n

Industrial-grade wax mold 3D printer has an accuracy of \u00b10.1mm and surface finish Ra\u22641.6\u03bcm, which can reduce the casting post-treatment process. Due to the large error of wax mold made by traditional process, the casting scrap rate is more than 15%; while the 3D printed wax mold reduces the scrap rate to below 5%, and a foundry produces large valve castings and reduces the loss of scrap by 800,000 RMB annually.<\/p>\n\n\n\n

3. Breaking through structural limitations and realizing difficult casting<\/h3>\n\n\n\n

No need to consider \"mold release\" issues, allowing for designs not possible with conventional processes, especially for high-end manufacturing:<\/p>\n\n\n\n

    \n
  1. Aerospace:Multi-layer cooling channels inside the turbine blades<\/strong>(The traditional process requires 5 sets of wax molds to be disassembled, while 3D printing molds the mold in one go, with no assembly errors);<\/li>\n\n\n\n
  2. Cars:Engine block integrated runners<\/strong>(Reduced post-drilling process and increased fluid efficiency by 10%);<\/li>\n\n\n\n
  3. Heavy machinery:Thin-walled honeycomb structure for large shells<\/strong>(Wall thickness as low as 2mm, weight reduction 20%, strength increase 15%).<\/li>\n<\/ol>\n\n\n\n

    4. Long-term cost reductions 40%, offsetting equipment investment<\/h3>\n\n\n\n

    Despite the high initial investment ($50,000+) for an industrial-grade wax-molded 3D printer, the cost advantage is significant when calculated over the full lifecycle:<\/p>\n\n\n\n
