## Overview

Protopasta FEP12801 Composite Iron PLA is a 2.85mm filament designed for 3D printing, featuring a unique matte gray finish that mimics cast metal. It allows for magnetic adhesion and can be processed without a heated bed, making it user-friendly. Ideal for artistic and functional prints, this filament is manufactured in the USA, ensuring quality and reliability.

## Description

Proto-pasta metal-filled composite hotplate is a combination of high-quality metal powder & high-performance PLA. The result is a PLA-like 3D printing experience that yields 3D printed prototypes & finished parts with metal-like properties. Mill, brush, polish, or patina for a personalized finish. Heat Treat for use up to 160C (320F) in demanding applications. Filament specifications: density 2. 2-2. 4 g/composites contain 60% metal by weighting bend diameter 50mmmachine compatibility: Must accept third Party filament, allow nozzle replacement, & Have adjustable parameters including layer thickness, temperature, & Speed with nozzle operating at min 215C. Heated bed Not required, but recommended up to 60C for improved part quality. Unpacking, handling, & Storage: mill, brush, polish, or patina to finish: what is hotplate & heat treating hotplate is a semi-crystalline grade of PLA optimized to survive heat treating (also known as annealing) for higher temperature use. Standard PLA loses form past 50-60c because amorphous materials see significant loss of stiffness at glass transition. Heat treating to create a crystalline structure allows hotplate to maintain useful Stiffness up to 160C depending on application, form, load, or other conditions. This greatly increases the usefulness of heat treated hotplate over standard, amorphous PLA.

## Features

- Create 3D printed parts with added weight and metal finish on PLA-compatible 3D printers.
- Cast look when printed. Mill, brush, polish, or patina. Heat Treat for use up to 160C (320F).
- Proto-pasta is crafted in the use for world-class quality, finish, and performance.
- 3D printing hardware and settings can vary greatly. Adapt printer to material for best result.

## Customer Reviews

### ⭐⭐⭐⭐⭐ Looks like copper, prints with no issues
*by B***S on January 20, 2021*

I printed this using slower PLA settings at 205c on an Ender 3 with no issues. When polished the filament looks like copper as advertised. Parts come out looking like terracotta at first and have a similar feel and density to them. Printed parts have a very nice feel. The filament is substantially weaker than regular PLA and should not be used for structural parts. Because the filament is fairly brittle you should use a filament guide or keep the filament from having to take any sharp turns.

### ⭐⭐⭐ Great, unique finish; expensive.
*by S***T on May 29, 2021*

Bottom line: $50 for 90m is steeepDefinitely adjust the material weight for this filament so you don't run out of the spool: 2.3 g/cc is heavy which means that 500g only gets you around 90m of filament in a spool.With some sanding and post processing, this really does shine like copper which is super cool for a 3D printed object like a pot or figurine.At 50% more $ per g than Colorfabb, think I probably won't buy this regularly.

### ⭐⭐⭐⭐⭐ This is neat stuff
*by S***I on January 15, 2022*

Disregard the shaving issue I had on the bottom layers. That has since been cured. But look at the finish I got on my first attempt here. Using suggested settings from Proto-Pasta on my CR-10 V3, this wall hook I printed out came out very strong. It looks more like terracotta when printed. Next one out I'm going to sand and patina it. My goal was to print some custom bases for my desktop sculptures.
