Getting Started with Proto-pasta PLAs including HTPLA

We've created this page to bring you a premium PLA and HTPLA printing experience that rivals our premium material. Follow below to improve your 3D printing experience. In other words, here's your shortcut to awesomeness with pasta. If at the end of this document you have questions or need assistance, please contact us at [email protected].

Filament Handling

Loose coils can be very tricky to manage. Going cowboy on your spool handling can quickly end up in a frustrating, tangled mess. Keep your loose coils wrangled with a spool holder like masterspool for a more trouble-free experience. Find out more about loose coil handling in Keith's blog post.

And for spooled filament, never let go of the loose end. When not in the printer extruder, tuck it away in the cardboard spool's corrugation! Also, avoid sharp bends and excessive force when loading filament into your printer.

Print settings

At Proto-pasta, we make high quality filament. We aspire to make exceptional results easy, but a positive result is very much dependent on your hardware, set-up, adjustments, and process parameters. Matching hardware with process and material for a positive experience is not always straight-forward, but you can start by pairing the following settings with your printer for a good starting point, then tune or troubleshoot as required.

Example settings for typical printer

Nozzle size = 0.4 mm (Standard to most printers & balances detail with productivity.)
Extrusion width = 0.45 mm (Typically larger than nozzle size. If using a larger nozzle diameter, be sure to set the extrusion width larger than that nozzle diameter.)
Layer thickness = 0.15 mm (For a balance of speed, quality & reliability.)
Speed(s) = 15-45 mm/s (Respecting mechanical and volume flow limits. Stay within the recommended speed range but apply slower speeds to the walls and faster speeds to the infill.)
Volume flow rate(s) = 1-3 cu mm/s (The result of above speed range, width, and layer thickness. Respect hardware and geometry limitations.)
Typical temperature = 215 C +/- 10 C (Matching material, hardware, and volume flow rate.)

Volume flow rate together with temperature dictates how melted the material is. This is hardware & condition dependent based on hot end, nozzle & extruder type, material & manufacturer as well as layer fan type, position & settings. Extrusion width, layer thickness & speed changes affect volume flow which may change required/desired temperature.

Additional settings of note

“Grid” infill type at 20-30% - “connect infill lines” unchecked (off).
Minimum 3 shells & 4 top/bottom layers for good surface quality.
Layer fan set to cool enough for build rate, but not so aggressive as to fail process by over-cooling nozzle and heater block.

Validation and fine-tuning

Single wall box to tune temperature and extrusion-related settings.
Protognome to validate results.

Post your prints & tag us @Proto_pasta on Twitter and Instagram. Need more help? Consider typical pitfalls and fixes below.

Typical pitfalls

Exceeding hardware capabilities.
Mismatch of flow rate and temperature.
Excessive nozzle cooling from layer fan yielding lower heater block and/or nozzle temperatures than set point.
Hardware shortcomings such as MK3 heat break, poor nozzle diameter, or other hangups.
Poor assembly or adjustment of components.
Excessive retraction distance or number of retractions.
Inaccurate flow with missing cross-sections or wall thickness not matching extrusion width software setting.

Typical Fixes

Heat break replacement with OEM, straight-through design and defect-free, smooth bore.
Proper assembly of components without plastic oozing gaps & with thermal grease.
Lightly oiling filament, but careful, a little goes a long way.
Reducing layer fan speed and/or isolating from heater block and nozzle.
Installing heater block sock to isolate heater block & nozzle from layer fan.
Increasing temperature to flow past internal hang-ups.
Reduce speed and/or choose a single speed for a single volume flow
Consider drive gear tension adjustment, bowden tube coupling/replacement, and spool mounting

Conductive PLA

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? Then Protopasta Conductive PLA is the perfect material for you.

How Conductive Is It?

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. Here are the results:

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: 2-3kohm
Resistance of a 10cm length of 2.85mm filament: 800-1200ohm

Suggested Applications

Protopasta Conductive PLA is a great choice for low-voltage circuitry applications, touch sensor projects, and using prints to interact with touch screens (which require low conductivity, that's why you can't use your smart phone screen with gloves on). As a general rule, anything you can run through a 1K resistor should be doable with our material (if you design the conductors to be the right size). This will easily run a low current Arduino, if you are not powering much with it. Also, experiment with ESD or 3D printed bearings!

What is it made out of?

Protopasta Conductive PLA is a compound of Natureworks 4043D PLA, a dispersant and conductive carbon black. In filament form, it is quite flexible, and is compatable with any PLA printing printer.

Strength and Performance

We have not done substantial mechanical testing on this product but have some subjective parameters that should be useful in comparing this material with others:

Strength: Fair strength. More flexible than PLA, but less layer adhesion
Stiffness: Low, semi-flexible
Heat Resistance: Similar to PLA, use below 50C
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

Print Settings

Protopasta Conductive PLA is quite easy to print and is compatible with most printers that can print PLA.

Density:

1.15 g/cm3 (1500 kg/m3)

Parameters:

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

Hot End Temp: 215 – 230° C (we run it on the hotter side to encourage layer adhesion)

Para uma correcta manutenção da sua impressora 3D, recomendamos sempre que trocar de material de filamento 3D, a efectuar uma purga com filamento especial de limpeza.
Desta forma garante que não ficam vestígios de material nas paredes do nozzle, evitando o acumular de crosta que é criado sempre que efectua trocas de material.
Com este produto evita problema como "clogs" e "jams" e fará com que o seu nozzle mantenha-se sempre limpo, durando muito mais tempo.

Para obter maior aderência à superfície da sua impressora 3D recomendamos a aplicar 3DLAC na base da plataforma.

Este material é altamente higroscópico, absorvendo rapidamente a humidade do ar passados poucos minutos após aberto, impossibilitando desta forma a correcta impressão 3D do mesmo. O resultado das impressões 3D de materiais com humidade tendem a ser frágeis e de acabamento irregular ou em certos casos, torna-se simplesmente impossíveis de imprimir.
Deverá de usar soluções de caixas fechadas com dessecante como sílica ou caixas próprias secadoras de filamento.
