# Polymaker PolyCast 2.85mm 750g

**Type:** Product page · **SKU:** CE06669 · **Brand:** [Polymaker](https://core-electronics.com.au/brands/polymaker-australia)
**Page:** https://core-electronics.com.au/polymaker-polycast-2-85mm-750g.html ([markdown](https://core-electronics.com.au/polymaker-polycast-2-85mm-750g.html.md))

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.

## Pricing

- **Price:** $43.42 (inc GST) — $39.47 AUD, exc GST

## Availability & dispatch

- In stock, ships same business day if ordered before 2PM (Australia/Sydney).
- We can dispatch 2 today, and up to 11 more in 7–8 days.

## How to buy

- **Build a cart:** compose `https://core-electronics.com.au/cart/link?items=CE06669:1` (comma-separated SKU:qty pairs) and share the link. Opening it shows a confirmation page with live pricing and stock before anything is added to the cart.
- **Verify the cart first:** fetch `https://core-electronics.com.au/cart/link/CE06669:1.md` for live line prices (inc & exc GST, quantity discounts applied), stock and dispatch estimates, and totals. Append `/to/{AU-postcode}` (or `/to/{country-code}:{postcode}`) before `.md` for delivery options and prices to that destination. Unknown, retired, or out-of-stock SKUs are flagged. (Query form `cart/link.md?items=...` also works but some robots parsers refuse query strings here.)
- **Checkout** is completed on-site and includes a captcha at the payment step. Share the cart link; checkout takes it from there.
- **Search the catalogue:** `https://core-electronics.com.au/search/{query}.md` (URL-encode the query; pages 2-3 at `search/{query}/{page}.md`; `search.md?q=` also works)

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.

### 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 heated bed or chamber required.
- **Complex Geometry** - By 3D printing with PolyCast, you can manufacture metal parts with complex geometries that are simply not possible through tooling, casting or subtractive manufacturing.
- **Optimized for support** - Polymaker have engineered PolyCast™ to print with supports that can easily break away from your parts and once your model is polished there is no scar left on the surface.
- **Uncompromised Quality** - Polymakers leading quality control process and rigorous in-house testing, and rigorous in-house ensure reliable printing and consistency across spools and batches.
