3DMart has shared many success stories about metal casting. Besides the finished products, are you curious about the production process? The video below takes you inside the factory to show you how lost-wax casting creates perfect metal parts!
．A New Form of Lost-Wax Casting
Traditional lost-wax casting required artisans to manually sculpt wax patterns from flat schematic drawings, with repeated communication and refinement, before proceeding to mold making. If structural changes were needed, it would take even more time and processes. Nowadays, more and more people are using 3D printing for prototyping, which can be completed within a day or even a few hours, right within the company. It's even possible to compare 3D printed prototypes with other assembly parts and conduct simple tests. If modifications are needed, simply adjust the 3D drawing and print again, then proceed directly to the metal molding step.
．3D Printing Filament Specifically for Casting
This special filament, PolyCast, is categorized under Polymaker's Specialty series and was developed specifically for lost-wax casting, offering a more economical and faster application model. Using PolyCast filament with a 3D printer can significantly reduce complex processing steps and costs, and greatly accelerate product delivery times.
．Two Technologies, a Perfect Match: Layer-Free and Ash-Free
．Layer-Free Technology:
Place the 3D printed object made with PolyCast into an atomized alcohol vapor environment. The entire process is automatically completed within the Polysher alcohol polishing machine. This principle uses a rapidly vibrating "nebulizer" inside the alcohol polishing machine to generate alcohol vapor. When the surface texture of the 3D printed product absorbs alcohol particles, a chemical change occurs, making the surface smooth, shiny, and polished (further reading: 3D Printing Polishing Time-lapse Video).
．Ash-Free Technology:
This allows PolyCast filament to burn cleanly without leaving any residue during lost-wax casting. These clean mold cavities can be used to produce perfect, flawless metal parts. This technology has led to increasing applications of 3D printing in lost-wax casting, significantly reducing the high costs and production time traditionally associated with CNC machining or mold manufacturing for small batches of metal parts.
．Make Your 3D Printed Parts with PolyCast
The good news is, while 3DMart previously only offered casting services in a collaborative capacity, it's now available for online purchase! In addition to entrusting us with casting services, those of you who own 3D printers can also buy PolyCast filament in our store to make anything you desire.
Using PolyCast special filament with an Ultimaker 3D printer to produce cast parts delivers cost-effective, high-quality industrial-grade results. Best of all, it allows for rapid in-house adjustments and prototype iterations. We are delighted to see all the contributions of 3D printing technology to industrial progress.
