WHAT IS PROTO-PASTA CONDUCTIVE PLA AND WHY IS IT INTERESTING?
Have you ever wanted to create something with your 3D printer that includes electronics? Maybe an LED, touch sensor, or some other genius invention to solve the world’s problems? Help us launch Conductive PLA and you will be able to!
Proto-pasta Conductive PLA is an FFF/FDM 3D printing filament designed for users interested in combining 3D Printing and electronics. It allows you to print conductive assemblies that integrate switches, potentiometers, LED’s, capacitive touch sensors, and more!
PROTO-PASTA CONDUCTIVE PLA HIGHLIGHTS
1-High electrical conductivity, between 60X and 700,000X more conductive than readily available conductive filaments at 15 ohm-cm
2-Compatibility with other PLA materials for use in dual-head printers with good layer adhesion for creating circuits
3-Reduced brittleness over existing conductive products (filament is quite flexible)
4-Excellent print quality
5-Proto-pasta Conductive PLA is affordable
WHAT IS IT MADE OF?
Proto-pasta Conductive PLA is a compound of Natureworks 4043D PLA, a dispersant and conductive carbon black.
HOW CONDUCTIVE IS “CONDUCTIVE”?
Great question! Here are the numbers:
Volume resistivity of molded resin (not 3D Printed) – 15 ohm-cm
Volume resistivity of 3D printed parts perpendicular to layers – 30 ohm-cm
Volume resistivity of 3D printed parts through layers (along Z axis) – 115 ohm-cm
Resistance of a 10cm length of 1.75mm filament – 1.8Kohm
Resistance of a 10cm length of 2.85mm filament – 600ohm
The measure normally used to characterize a conductor is “volume resistivity” with the units of Ohm-cm. This can be confusing because it is not obvious what it means like “miles per hour”. It is simply the resistance through a 1cm X 1cm X 1cm cube of material, with full sheet contact at 2 opposing surfaces. It is often misprinted as ohm/cm which is not a common unit of measure.
We measured the conductivity using a fixture we machined that clamps a sample between 2 sheet conductors and 1cm cubes printed on a Printrbot Simple Metal and machined from solid resin.
