## Description

[Pici](https://en.wikipedia.org/wiki/Pici) up this filament today! It'd be [Fusilli](https://en.wikipedia.org/wiki/Fusilli) not to buy this filament! Adafruit can't [tagliatelle](https://en.wikipedia.org/wiki/Tagliatelle) you enough about this filament. Are these puns [Spirali](https://en.wikipedia.org/wiki/List_of_pasta)-ng out of control?

Sorry! Adafruit had to get that out of Adafruit's system. Proto-pasta's fun packaging makes Adafruit hungry for Italian food. If you're hankering for unusual and unique material filaments, Adafruit have got a new spool of noodles for you!

This **Proto-pasta 2.85mm Diameter 500g Filament** **in Magnetic & Rustable Iron** opens up a new world of 3D-printed fun *with* electronics!

Proto-pasta Conductive PLA is an FFF/FDM filament, so now you can print circuit assembles with [touch or light sensors](https://core-electronics.com.au/#) or [LEDs](https://core-electronics.com.au/#) to your gamut of 3D printed creations!

Since this filament behaves similarly to iron, it's actually [ferromagnetic](https://en.wikipedia.org/wiki/Ferromagnetism), as opposed to magnetic. This means that magnets will stick to items printed with this filament, but 3D printed projects **will not** behave as magnets.

This filament behaves similarly to iron - even to the point of rusting - making it a fantastic choice for costumes and props, so you can achieve that beautiful, aged appearance.

And, of course, even though it has the word "Pasta" in the name, it's *not* for eating.

This filament performs best when extruded between **185°C and 215°C**.

## Technical Details

**Resistivity:**

- Volume resistivity of molded resin (not 3D Printed): **15 ohm-cm**
- Volume resistivity of 3D printed parts along layers (x/y): **30 ohm-cm**
- Volume resistivity of 3D printed parts against layers (z): **115 ohm-cm**
- Resistance of a 10cm length of 2.85mm filament: **600ohm**

**Bed Temp** (if available, is not required): **50°C**

**Hot End Temp**: **215 – 230°C** (Proto-pasta runs it on the hotter side to encourage layer adhesion)

**Performance:**

- Strength: Fair strength. More flexible than PLA, but less layer adhesion
- Stiffness: Low, semi-flexible
- Heat Resistance: Similar to PLA, use below 50ºC
- Layer Adhesion: Fair layer adhesion. Not as good as normal PLA
- Flexibility: Filament is quite flexible but will break if bent repeatedly (particularly 2.85mm). Printed parts are rigid if more than a mm or two thick. Thin sections are somewhat flexible but fail along layer lines if flexed more than a few times.
- Failure Mode: If flexed to breakage, failure will be along layer lines.
- Warping: Very low warping
- Dual-Head compatibility: Compatible with (sticks to) PLA in dual material prints

Proto-pasta Conductive PLA is a compound of Natureworks 4043D PLA, a dispersant and conductive carbon black. In filament form, it is very flexible, and is compatible with any PLA printing printer.
