Do you remember the previous article that mentioned how to make bicycle part castings?
The shiny metal parts are super eye-catching; everyone who saw them thought they were off-the-shelf products, but in fact, they were also made using 3D printing. Go back to the previous article
to review the production method!
In this article, we will also introduce castings, but this time they are parts from inside an airplane!
We used the Ultimaker3 3D printer for printing, and the filament used was special industrial-grade polycast filament. It can be sent directly to the manufacturer after printing to create molds,
resulting in metal parts with near-finished product quality.
3D Printing Filament Fact: PolyCast is a material specifically designed for metal investment casting (lost-wax casting). It can be polished with an alcohol polishing machine and completely burns away during
casting to ensure the integrity of the mold cavity.
After carefully removing the supports upon completion of printing, you have the printed product! It is then directly handed over to the foundry for post-processing. Please see the image below of the final part after casting and
grinding and polishing!
The details of aircraft parts are more complex, such as the thinner parts of the central bracket, which cannot be produced using industrial machines like CNC. However, by using a 3D printer,
you can easily complete them, and you don't need to worry about needing large quantities for production; even a single item can be made.
Now you can use a 3D printer for prototyping and completing final part testing. If you are interested in PolyCast 3D printing filament and would like to learn more,
