Our initial test is here again! Not only Chunghwa Telecom is leading the way for you, but also our 3DMart is. Do you all remember the Ultimaker S5 large-scale 1:1 brake caliper test last time?
After the success last time, we thoughtfully considered the actual 3D printing mold opening situation for our customers. This time, we used PolyCast for printing. This material is specifically designed for investment casting (lost-wax casting) of metals. Not only can it be used with the Polysher alcohol polishing machine (latest offer: buy before August 10th and get a roll of Polysmooth filament!), but it can also completely melt within the gypsum mold to create the mold cavity before metal pouring.
Now, let's reveal the actual situation! One of the advantages of Ultimaker S5 large-scale printing is that it can directly print PVA support material and the main body, completing both at once and saving a lot of time. Printing the main body takes about four days.
After dissolving the support in water, the main body before casting is ready!
We specially took close-up shots for everyone to examine the details. As you can see, aside from some minor 3D printing textures, the holes are printed quite completely and with precise shapes.
We sent this 3D printed PolyCast model to the manufacturer, and a few days later, the metal model arrived!!
Holding the actual metal model feels completely different; it's very heavy! The boss spared no expense to prioritize testing for everyone, which is truly heartwarming!
This isn't Darth Vader from Star Wars, but its power is just like Darth Vader's! From 3D printing to a fully functional 1:1 metal casting, without expensive molding fees and time costs for back-and-forth modifications; at this point, only fine-tuning with CNC is needed, and the prototype will be complete. What an exciting result!
The finished metal model is very beautiful, and the details are also well-defined. The round holes in the picture are also very clear and complete.
Don't doubt your eyes! You can take a closer look!
Placing the two "twins" together, from 3D printing to metal casting, is truly presented before your eyes. If this method is used for rapid prototyping, it will be a major breakthrough for many industrial processes!
We will continue to try new 3D printing methods for everyone to ensure the best quality. If you also need contract manufacturing services for metal casting prototypes, please feel free to contact us.
