Glass-fibre reinforced HT-PLA for the workshop with heat stability up to 130°C right off the printer and high HDT after annealing.

Not everyone has the capability to print in high temperature filaments such as PETG, ASA or Nylon and some hobbyists and educators choose to only print in PLA. As we all know - PLA has always deformed in the heat, limiting the applications for these users. Polymaker™ HT-PLA-GF offers ABS-like heat resistance after annealing while maintaining PLA's ease of printing. It’s ideal for applications requiring high thermal stability, withstanding temperatures up to 130°C without load and up to 110°C with a load. The high softening temperature is achieved before annealing, but the heat deflection temperature is achieved through a very short annealing process (30 minutes at 100°C).

Features

  • High Heat Stability - Polymaker™ HT-PLA-GF delivers high heat stability up to 130°C right off the printer, no post-processing required. Heat stability refers to the ability to remain dimensionally stable at elevated temperatures under no or minimal external load other than its own weight.
  • ABS-like Heat Resistance - For applications under load, users can quickly increase the heat resistance of Polymaker™ HT-PLA-GF by annealing parts in an oven at 100°C for 30 minutes. The glass-fibre reinforcement in Polymaker™ HT-PLA-GF significantly minimises shrinkage during annealing, an issue that many generic HT-PLA materials face. With a high heat deflection temperature, Polymaker™ HT-PLA-GF is the perfect choice for power tool accessories, custom PC & printer components, heat shields and fan ducts.
  • Glass Fibre Reinforced - Polymaker™ HT-PLA-GF is glass fibre reinforced which significantly boosts tensile strength and stiffness for a wide range of functional applications that also require heat stability or heat resistance. It is worth noting that HT-PLA-GF exhibits lower z-axis layer adhesion compared to normal PLA. This is fairly standard for glass-fibre reinforced materials, but worth noting as the reduction in Z axis strength is not ideal for some single-wall prints.
  • High Speed Capable - Polymaker™ HT-PLA-GF is based on a high-speed PLA formula, enabling high speed printing up to 350mm/s and compatibility with a wide range of 1.75mm diameter machines. An enclosure is not needed for this high temp filament! You simply need a wear resistant nozzle due to the addition of glass-fibres.
  • No Compromise - At its core Polymaker™ HT-PLA-GF is a PLA-based multiphase composite, built around NatureWorks PLA so you can expect similar chemical resistance and the same low shrinkage rate as normal PLA. 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.

Applications

Power Tool Accessories

Every year many 3D printer battery holders, tool holders, trays, custom drawer inserts and vacuum attachments are printed in regular PLA and quickly deform on a hot summer day. Combining the printability of PLA with similar heat resistance to ABS (after annealing), Polymakers four power tool colours deliver the perfect companion for your shed.

Now you can print the perfect range of accessories to suit your needs, or start selling printed accessories for other hardware enthusiasts.

Electronics Housings

The heat resistance of Polymaker™ HT-PLA-GF delivers the perfect choice for printing temperature resistant housing, cases and product modifications within the home. With the same ease-of-use as normal PLA, Polymaker™ HT-PLA-GF is an accessible option for these hobbyist projects.


Custom Solutions, Jigs and Holders

Whether it be a custom jig for soldering or cutting. You want it to be ready to use when you need it - rather than quickly discovering is softened and deformed on a hot summer day. The high mechanical strength of Polymaker™ HT-PLA-GF and the optimised heat resistance after annealing - deliver the perfect companion for these projects.

Compatibility

Polymaker™ HT-PLA-GF has been engineered with compatibility in mind to print excellently on a wide range of 3D printers. As the glass fiber in this material is highly abrasive we recommend customers first check that their 3D printer is equipped to print abrasive materials before purchasing this product.

High rigidity materials like Polymaker™ HT-PLA-GF work best in set ups where the filament guide system is smooth and as no harsh bends.

Of course with thousands of unique 3d printer models on the market, we can't guarantee each filament type will work with every 3D printer. Slicer experience and setting adjustment is always required to get the most out of a material. Before jumping into an ambitious project we always recommend printing some known calibration tests to build or make adjustments to the filament profile.

Additional tips for HT-PLA-GF

  • Polymaker™ HT-PLA-GF is a fairly stiff filament. During printing it is recommended to have a smooth feeding path to ensure optimal feeding. For example we recommend avoiding excessive bending in the filament guide system.
  • Polymaker™ HT-PLA-GF features glass fibres that can easily damage a brass nozzle. Nozzles come in many different materials from soft to hard and the heat conductivity of a nozzle can change depending on what material it is made of. Hardened steel is more abrasion resistance than brass or a nickel plated nozzle.
  • Inter-layer strength can depend significantly on your extrusion temperature which is a result of your printing speed, nozzle type and hot end. A higher nozzle temperature / extrusion temperature can offer significant benefits in regards to inter-layer strength.
  • Annealing parts printed in Polymaker™ HT-PLA-GF is not needed for applications where parts are exposed to temperature with no mechanical force (heat stability) Annealing is highly recommended if you need a high heat deflection temperature, please read below. 

Annealing HT-PLA-GF

Annealing will have minimal impact on vicat softening temperature, allowing a wide range of low force applications with heat exposure.

For functional applications that will be under force and require heat resistance, we highly recommend annealing which will boost the heat deflection temperature. Annealing is the process of heating up the printed parts at a certain temperature for a certain period of time. Fiberon™ PA6-GF25 displays outstanding mechanical and thermal properties when fully crystallised. The printed part will not reach full crystallisation after the printing process and annealing shortly after the printing process is required to complete this step.

We strongly recommend 100°C, 30 minutes annealing to achieve the best performance of the material.

The glass fibers in HT-PLA-GF help to minimise shrinkage, but to avoid deformation of the prints during annealing, please pay attention to the following:

  1. Before annealing ensure that the temperature in the oven is uniform by pre-heating your oven first and make sure there are no obvious obstructions that cause uneven temperature of the sample.
  2. During annealing, do not touch the sample with your hands or apply any additional load to the sample.
  3. For thin-walled areas with a wall thickness of less than 4mm, you can try to add reinforcing ribs or increase the wall thickness to avoid possible annealing
    deformation.
  4. In principle, the best orientation would be consistent with that during printing.
  5. After annealing time finishes, you don't need to let the model gradually cool. You can just remove the model.

Thick, durable jeans for a good price!
Size: 34W x 34L, Color: Tinted Dark Wash
I bought these for my son. They fit well - true to size. They feel thick and durable. He says the fabric is a little stiff, which makes them wrinkle, so he doesn't wear them as often as some other jeans.

They are dark blue and are great especially for the price.
Size: 38W x 28L, Color: Tinted Dark Wash
They fit true to the size and the dark blue color is perfect...!!! I did wash them in hot water and put them in the dryer on low temperature before I wore them and they fit perfect. And I am 5'6" weight about 215lbs. I bought the 38 waste and 28 length and athletic fit stretch and they do stretch and I absolutely love them...!!!

Great jeans, waist is too high
Size: 40W x 30L, Color: Tinted Light Wash
These pants, so far, have been well made and are almost identical to Levi's 541 style jeans. They have almost the exact same fit and are comfortable. There is only one detractor, the waist is about an inch and a half too high. I compared it to my 541's and that is the only difference. I am glad I know about this now. Other than the waist height, I would absolutely buy these again.
