It can print in a very wide temperature window and is compatible with most extrusion-based 3D printers.
Features
- Matte Surface & Fun Colours - Print parts with a beautiful matte surface finish and unleash your imagination with PolyTerra™ PLA's fun and vibrant colour range. PolyTerra™ PLA renders models with excellent surface quality and features great overhang and bridging capability.
- Optimized for Support - PolyTerra™ PLA has been engineered with excellent support removal properties, enabling users to more easily break away support or rafts from the surface of their prints.
- Easy Sanding - PolyTerra™ PLA is softer and easier to sand in comparison to regular PLA filaments and can be easily painted.
- High Speed Capable - Polymaker have engineered the base PolyTerra™ PLA formula with ideal flow properties to deliver a filament which is capable of high speed printing (only on suitable hardware)
- Bioplastic Matte PLA Formula - PolyTerra™ PLA is based on a newly developed material from Polymaker called FBC (Fully Bio Compound). It is a compound of high quality Ingeo PLA compounded with naturally occurring elements. The result is a PLA filament with less plastic content that feels softer and more ductile / less brittle on the spool. Polymakers FBC formula contains less PLA plastic to degrade which improves the speed of degradation under specific industrial conditions. Like other PLA's, the degradation rate is still very slow in ambient temperatures.
- Ductility (X-Y) - PolyTerra™ PLA is softer than regular PLA, delivering improved ductility in the horizontal X-Y axis than standard PLA formulations. Whereas a test bar in standard PLA will snap when bent, PolyTerra™ PLA will tend to gradually bend and fracture in the horizontal axis.
- Improved Ductility - PolyTerra™ PLA delivers improved ductility which is less brittle (Charpy Impact) in X-Y axis than standard PLA formulations.
- Compatibility / Jam-Free™- PolyTerra™ PLA is compatible with a wide range of 3D printers and is manufactured with Polymakers Jam-Free™ technology which leads to excellent printing quality with zero risk of nozzle jams caused by heat creep [1]. PolyTerra™ PLA works well on many printing surfaces with a thin layer of glue stick applied, no heated bed is required but can be used at 40 - 50°C for better results (maximum 60°C).
- Uncompromised Quality - PolyTerra™ PLA filament is made with the highest quality ingredients including Ingeo® from Natureworks; a high quality PLA material produced from rapidly renewable plant resources in the US. Combining Polymakers innovative R&D technologies, compounding and extrusion systems with Natureworks Ingeo® resins produces a reliable 3D printing filament to print beautiful and accurate models.
[1] Heat creep is the the process of heat spreading irregularly throughout the hot end, one common example is with all metal hot end designs. Once heat creeps towards the cold end, the PLA filament softens prematurely in the cold end and expands resulting in a jam. Polymakers Jam-Free™ technology increases the heat resistance of the filament itself (not the printed part) to 100˚C which prevents the filament from prematurely softening in the cold end and can still melt rapidly once entering the heating zone.

Compatibility
All plastics are hygroscopic meaning they absorb moisture from the air which can affect printing quality and strength of printed parts. How quickly this absorption occurs depends on the material and your environment. Polymakers PolyTerra™ PLA filaments are dried and packaged in a vacuum sealed bag with desiccant to ensure the best printing quality. When not in use PolyTerra™ PLA should be stored away from sunlight and sealed in the packaged resealable bag.
Although filaments can be dried, drying will speed up the aging process of the plastic making it more brittle over time. Preventing the filament from absorbing moisture in the first place is the best solution to keep your filament working to its maximum potential. For long term storage we highly recommend storing in a sealed container with dry desiccant that reduces the relative humidity to 10-20% RH.
In-house we manage our filaments with Polymakers PolyDryer™ which keep offers best-in-class sealing to protect filaments from absorbing moisture
If you hear popping sounds and notice that the surface quality of your print is uneven or the colour is not consistent, this is a likely indicator that the filament has absorbed too much moisture. Spools of PolyTerra™ PLA can be dried with Polymaker PolyDryer™ using power level 1. Alternatively if you have a convection oven that is accurate at low temperatures, users can dry filament in a preheated convection oven at 55˚C for up to 6 hours. Results may vary depending on the accuracy of your oven so please be conservative. For more information about filament drying please read our user guide.

STORAGE & DRYING
Like other PLA filaments, PolyTerra™ PLA is susceptible to absorbing moisture from the air which can subsequently effect the print quality and mechanical properties of the final prints.
Although filaments can be dried, drying will speed up the aging process of the plastic making it more brittle over time. Preventing the filament from absorbing moisture in the first place is the best solution to keep your filament working to its maximum potential. For long term storage we highly recommend storing in a sealed container with dry desiccant that reduces the relative humidity to 10-20% RH.

FAQ
Q: Does Jam-Free™ technology prevent all filament jamming?
A: Jam-Free™ technology is designed to prevent jamming caused by heat creep. There are many reasons why a material may jam, such as printing with the wrong extruder temperature or incorrect nozzle height; Polymaker's Jam-Free™ technology won't prevent jamming in these cases.
Q: Is PolyTerra™️ PLA food safe?
A: Polymaker's PolyTerra™️ PLA is compliance with RoHS Directives 2011/65/EU and (EU) 2015/863 and REACH regulation, which means it does not contain toxic or harmful substance listed. However due to the nature of FDM 3D printing, the printed PolyTerra™️ PLA parts might have micro-cracks and holes which are invisible to the naked eye even though the prints look smooth. Bacteria are prone to grow in these micro-cracks and holes and thus we do not recommend to use the 3D printed parts in food contact applications.
Q: How long does it take for PolyTerra™️ PLA to degrade?
A: PolyTerra™️ PLA degrades under the specific conditions of industrial composting, namely, at certain temperature and humidity with the presence of micro-organisms. The degrade rate will depend on the size and thickness of the printed part. Polymaker has run a compostability test, certified to ISO 14855-1, with a third party laboratory that revealed PolyTerra™️ PLA degraded faster than a comparable PLA material. The test was completed by putting small pellets of PolyTerra™️ PLA in a 2-4 months old plant compost (including a wide variety of microorganisms) and heating up the system up to 60˚C. During this process the PolyTerra™️ PLA will start to decompose into carbon dioxide, water and mineral salts and the aforementioned elements are monitored in order to calculate the mass of PolyTerra™️ PLA degraded. After 45days, 93.6% of PolyTerra™️ PLA degraded and from Polymakers estimation it could take less than 100 days for PolyTerra™️ PLA to fully degrade. Polymaker ran the exact same test with their PolyLite™️ PLA which is a pure regular PLA and, after 45days, 79.9% of it degraded. Which means PolyTerra™️ PLA degrades up to 15% faster than regular PLA.
Q: What support materials can I use with this product?
A: PolyTerra™ PLA has been engineered with excellent support removal properties, enabling users to more easily break away support or rafts printed in PolyTerra™ PLA. Polymaker’s PolyDissolve™ S1 or PolySupport™ filament are the recommended support filaments for PolyTerra™ PLA if your machine is capable of multi-material printing. If your 3D printer is not equipped for multi-material, self-support can be used.
Q: Should I rewind this filament if I want to use it with a different spool?
A: We strongly advise against tampering with the product by rewinding. See our article for full details about the risks. All Polymaker filaments are wound with tension but without strain. Rewinding completely rearranges the curvature of the winding and this strain over time can cause most plastics to catastrophically break. If for some reason your printer is locked into fitting less than standard sized spools, there may be safe printable adaptors or external mounting solutions available.

Applications
With a cost-effective price and extensive colour range, PolyTerra™ PLA has quickly become one of our best selling PLA filaments; especially among hobbyists and educators who enjoy printing PLA but are looking for a more sustainable filament.
Offering a new type of PLA filament, PolyTerra™ PLA is a popular Matte PLA choice for printing:
- Trinkets and figurines.
- Homewares and desk organizers.
- Custom fashion accessories.
- Replica props and display pieces.
- Low cost cosplay pieces.
- Medium - large tabletop buildings and scenery.
- Various models which would typically be difficult to remove support from. (Not ideal for particularly thin or delicate features which could be broken during support removal)
- Architectural models and educational models.
PolyTerra™ PLA has also seen adoption beyond the education and consumer market as a more sustainable alternative for various concept, design and prototyping applications. As we become more aware and considerate of our own consumption habits, many small businesses are looking for ways they can become more ethical and improve the sustainability of their products. While the end 3D printed product is inevitably plastic, PolyTerra™ PLA reduces plastic consumption with Polymakers FBC formula, cardboard spool and a step forward towards sustainable packaging.
Compared to regular PLA materials, PolyTerra™ PLA is softer, less brittle and more ductile in X-Y axis. Ductility describes how a material breaks, if you flex the filament in your hands a ductile material is more likely to bend gradually in comparison to a brittle material which will suddenly snap. Although PolyTerra™ PLA isn't intended as a high strength material, its ductility can offer advantages for quite a few end-use applications.
In comparison with PLA and PLA+ materials like PolyLite™ PLA and PolyLite™ PLA Pro; PolyTerra™ PLA exhibits better support removal properties, enabling users to more easily break away support or rafts from the surface of their prints. Combined with great compatibility with sanding and painting, PolyTerra™ PLA has become a popular choice for printing relatively large scale table top models and cosplay pieces. This easy break away of supports correlates with lower inter-layer strength in the z-axis, so additional care may be required when handling thin or delicate features which have been printed vertically. If both sustainability of Polymakers FBC formula and strength are more important than support removal, we recommend considering PolyTerra PLA+ which is a strength optimised version of Polymakers FBC formula, prioritised for layer-adhesion over support removal.
For applications which require a PLA with particularly high mechanical properties, we recommend comparing PolyLite™ PLA (PLA), PolyLite™ PLA Pro (PLA+) which both offer higher tensile strength, rigidity and inter-layer adhesion than PolyTerra™ PLA or PolyTerra™ PLA+. If a multi-material printer is available, comparable support removal process to PolyTerra™ PLA can be achieved by printing these PolyLite™ PLA and PLA Pro materials with a dedicated support material such as PolySupport™ which has been designed to be easily removed from the model by hand.
