After the rise of 3D printing technology, in addition to FDM, SLS, and SLA technologies, previous exhibitions have shown that metal 3D printing technology is also under development (further reading: 2018 Formnext Exhibition Correspondent, Bringing You 3 Major Innovative Technologies!); since the technology is not yet widespread, the current prices of metal 3D printers start in the millions or tens of millions.
Beyond this price, the currently popular general 3D printing technology, after a brief conversion process, can provide high-quality metal parts. Below, we'll show you 3DMart's large family of 3D printed casting parts, from small to large objects!
．SLA Photocuring: Jewelry and Metalworking Series
We have previously shared some photos of metal castings, which were printed using DWS XFAB with resin. After the original piece is printed, it is then melted to create a metal mold.
The forming characteristic of SLA photocuring technology is its smooth surface and delicate details, making it suitable for small, intricately structured, and finely detailed jewelry.
It is especially useful for customized or bespoke items, eliminating the need for expensive milling or mold-making costs. The images show the flow of a person's hair and the texture of flower petals; we used a hand as a size reference in the photograph.

．FDM Fused Deposition Modeling: Industrial Parts and Portrait Series
Most people are more familiar with FDM technology, which uses filament for 3D printing. By using the newly launched PolyCast filament specifically for casting to create prototypes, a clean mold cavity that completely melts away can be quickly obtained for casting metal parts. In addition to being meltable, the casting-specific PolyCast can also be alcohol polished; it can be transformed into a smooth surface before casting, and it will not leave behind the stacking marks typical of general 3D printing in the mold cavity, making it the best choice for prototyping.

You can refer to the previously finished bicycle parts and the final metal samples of aircraft components. From 3D printing to metal parts, there are usually four steps: 3D printing prototype, alcohol polishing, casting prototype, and metal polishing, to obtain the most perfect metal product.

Unlike CNC milling, 3D printing uses an additive manufacturing method, which allows for structures or internal curved angles that cannot be directly produced by some milling processes. The combination of both technologies can also complement each other to achieve more refined products. Compared to photocuring, FDM is more cost-effective and can print larger objects; for example, we once demonstrated a 3D printed 1:1 brake caliper, with overall dimensions of approximately 25.5mm x 16.5mm x 78.5mm, and of course, even larger parts can be printed.

In addition to these samples, you can also check out the application case of Sylatech, a foreign metal mold company, using this technology for investment casting; the image shows the final product used for metal propeller molding.

If you are interested in a real-world demonstration of PolyCast for casting, you can also refer to the video here! If you don't yet own a 3D printer, we also offer 3D printing service and subsequent casting; if you already have an idea and a machine, PolyCast is now available for sale, you can buy it in our online store!
