Polymaker PolyCast Metal Filament

PolyCast™ is a filament designed to produce investment patterns for investment casting applications. 3D printing significantly cuts down both the cost and lead time by eliminating the tooling process.

PolyCast™ features Polymaker's Layer-Free™ technology and Polymaker's Ash-Free™ technology:

Layer-Free™ - Layer-Free™ technology involves exposing a 3D printed part to an aerosol of micro-sized alcohol droplets, generated by a rapidly vibrating, perforated membrane called the nebulizer. The aerosol will then be adsorbed by the surface of the 3D printed part and render it smooth and layer-free.
Ash-Free™ - Ash-Free™ technology allows Polymaker’s filament which has been designed for investment casting to burn off cleanly without any residue, enabling defect-free metal parts. 3D printing has been used to produce investment casting patterns as it cuts down both the cost and lead time for small-volume production runs.

Polymaker PolyCast Technologies

Features:

No Ash - PolyCast™ burns off cleanly without any residue, enabling defect-free metal parts.

Low Cost - PolyCast™ is a cost-effective solution, with a lower cost compared to other 3D printing technologies (e.g. SLA/DLP/SLS). 

Effortless Post-processing - PolyCast™ can be effortlessly post-processed in the Polysher™ (sold separately) reducing layering and delivering superior surface quality.

Easy-to-print - PolyCast™ is compatible with most 3D printers, printing under similar conditions to PLA with no heated bed or chamber required.

Uncompromised Quality - Polymakers leading quality control process and rigorous in-house testing, ensure reliable printing and consistency across spools and batches.

Polymaker 3D Printing Filament

Polymaker is an international team passionate about 3D printing. They produce the very best 3D printing materials by controlling every stage of production. With a diverse portfolio of materials ranging from high performance plastics to unique aesthetic solutions, Polymaker will continue to add cutting edge materials to its ever-growing portfolio.

At the core of Polymaker is their research & development laboratory, this is where all Polymakers materials are formulated and fine-tuned from the ground up to create the best in class 3D printing materials. Polymakers precision testing equipment combines the latest advancements in technology to ensure they are ahead of the game.


Ash-Free™ technology

Ash-Free™ technology allows Polymaker’s filament which has been designed for investment casting to burn off cleanly without any residue, enabling defect-free metal parts. 3D printing has been used to produce investment casting patterns as it cuts down both the cost and lead time for small-volume production runs.

Layer-Free™ technology

Parts printed in PolyCast™ can be polished in Polymaker's Polysher™ which uses Polymakers Layer-Free™ technology.

Layer-Free™ technology involves exposing a 3D printed part to an aerosol of micro-sized alcohol droplets, generated by a rapidly vibrating, perforated membrane called the nebulizer. The aerosol will then be adsorbed by the surface of the 3D printed part and render it smooth and layer-free. 

Polymakers Polysher™ and Layer-Free™ technology is intrinsically safer than other smoothing techniques:
-  No heating is involved 
-  The nebulizer technology requires only a very small reservoir 
-  Isopropyl Alcohol is safer than smoothing chemicals like Acetone or MEK
-  It is a liquid-phase polishing rather than vapor-phase polishing process (the latter is more dangerous for a number of reasons)

Polymaker have also implemented a number of safety features into their Polysher™ machine: 
- Multiple sensors to detect any sign of malfunction of the nebulizer (e.g. running dry) 
- Chamber open/close sensor (the machine won’t start if the chamber is open, and will automatically terminate if the chamber is accidentally open during polishing) 
- All electronic components (running at very low voltages) are properly sealed, and no spark can be generated inside the chamber.

PolyCast™ 3D printed parts do not print with a smooth and glossy surface, this is achieved by post-processing the part. Polymakers Layer-free™ and Polysher™ technology offers a unique, safe and easy way to post-process 3D printed parts.


Industry Leading Quality Control

Polymaker 3D Printing Filament

PolyCast™ like all other Polymaker materials is manufactured using state-of-the-art polymer processing technologies and equipment. Polymakers rigorous minimum 8 quality control processes ensure industrial standards of reliability for a consistent customer experience.
Tolerance: Polymakers custom developed extrusion, control and monitoring solutions to ensure filament tolerance and roundness meet Polymakers strict quality standards.
Reliable Mechanical, Colouring & Printing Properties: Every batch of filament products are tested to ensure all quality specs (melt flow, softening point, mechanical, diameter, round-ness) are met.
Drying & Vacuum Sealing: Before packaging, all Polymaker filaments are dried to a moisture level of < 0.1% to ensure the best printing quality and are vacuum sealed to protect the filament from moisture. All vacuum packaged products are left for 24 hours before boxing to ensure they are leak-free.


Packaging

Transparent Spool: PolyCast™ is wound on Polymakers 1kg transparent spools. With the transparent spool, it is easy to see exactly how much filament is left for your next printing project.
Resealable Bag: PolyCast™ is packaged in a vacuum sealed resealable bag to ensure your filament is moisture free. Like all other PVB based filaments, PolyCast™ is hygroscopic so we recommend keeping this bag for filament storage.

Storage & ​Drying: We recommend that the material be used with the PolyBox™ to keep the filament at dry conditions (relative humidity of 15% or less) to maintain the best printing results. When not in use PolyCast™ should be stored away from sunlight in the packaged resealable bag. If the filament does absorb moisture, spools can be dried in a preheated convection oven at 60˚C for up to 12 hours. Results may vary depending on the accuracy of your oven so please be conservative. For more information about filament drying please read our user guide.

FAQ

Q: Is PolyCast™ a wax or PLA filament?
A: PolyCast™ is neither a PLA or wax based filament; it is based on PVB (polyvinyl butyral), formulated specifically to burn off cleanly without any residue with the opportunity to remove layers lines easily.

Q: Will Polymakers Layer-free™ technology improve the quality of my 3D prints?
A: Polymakers Layer-free™ technology is designed to improve the surface quality of 3D prints while maintaining details including textures and dimensions The best post-processing results will be achieved when PolyCast™ has been printed with fine layer heights and no defects. If a part has been printed with defects or a rough surface finish, these defects will be maintained in the same way that details are preserved. In these cases users willing to the detail of their print can over-polish the part to soften the impact of the defect.

Q: Can PolyCast™ be printed at large scales without warping?
A: PolyCast™ offers very similar dimensional stability to PLA and PETG and can certainly be printed at large scales without warping. When printing large objects we recommend a consistent room temperature and setting your heated bed to 70˚C. Please note while PolyCast™ doesn't warp in most situations, printing in a cold environment or with poor first layer adhesion can cause any material to warp.

Q: What support materials can I use with this product?
A: Polymaker’s PolyDissolve™ S1 filament is the recommended support filament for PolyCast™. If your 3D printer is not equipped for multi-material, self-support can be used.
