  6. What To Look For in Flexible Filaments

    Leave a Comment

    A flexible filament, also called flexible 3D printing material, is a category of thermoplastic polymers specifically formulated to achieve elasticity and resilience. Unlike traditional rigid filaments, their flexible counterparts can bend, twist, and deform without breaking. They can also produce objects with dynamic shapes and intricate geometries.

    However, not all filaments possess equal flexibility and capacity. With a vast selection of options, it is crucial to grasp the key factors to consider when choosing the optimal material for particular applications. Here are some of the essential considerations to look for in a flexible filament:

    1. Shore Hardness

    Shore hardness measures the material’s resistance to indentation or penetration by a rigid object. It is a standard method for assessing the hardness of various materials, including polymers, elastomers, and rubbers. Higher Shore hardness values indicate greater hardness and less flexibility, while lower values entail softer and more flexible materials.

    For instance, a filament with a high abrasion resistance requires a material with a greater Shore hardness. In contrast, a lower Shore hardness may be more appropriate if flexibility or impact resistance is essential. It ultimately depends on the application’s specific requirements and constraints.

    2. Elongation at Break

    Elongation at break is a mechanical property that measures the ability of a material to stretch or deform under tension before it breaks. This property is particularly important for materials that will experience stretching or elongation in their intended applications. For example, materials with high elongation at break values indicate excellent ductility and the capacity to undergo significant elongation.

    3. Tensile Strength

    Tensile strength is a mechanical property measuring the maximum tensile or pulling force a material can withstand before it breaks. High tensile strength indicates that a material can withstand greater forces without breaking.

    Remember that composition, microstructure, manufacturing process, and environmental conditions affect tensile strength. Different materials also have distinct inherent tensile strength capacities, and the desired value should be determined based on engineering specifications and safety factors.

    4. Printability

    Printability is the suitability and ease of 3D printing a specific material on a particular 3D printer. It encompasses several factors influencing a material’s successful and reliable printing, including filament properties and printer settings. It also includes the interaction between the material and the printer’s hardware.

    5. Diameter and Consistency

    The filament diameter is the thickness of the filament strand used during the printing process. The typical filament diameters for consumer-grade printers are 1.75 mm or 2.85 mm, while industrial printers may utilize larger filaments. Therefore, selecting a flexible filament with a diameter that aligns with the correct specifications of the printer is essential to ensure optimal performance.

    Consistency refers to the uniformity of the filament diameter along its entire length. When the filament exhibits consistent diameter, it facilitates a smooth and uniform extrusion process, resulting in even material deposition. In contrast, inconsistent filament diameter can cause under-extrusion, over-extrusion, or nozzle clogging.

    Click to ExpandWhat-To-Look-For-in-PLA-Filament-Options

    Polylactic acid (PLA) is a popular 3D printing filament made from renewable resources, such as cassava, cornstarch, and sugarcane. It has a biodegradable composition and low melting point, making it ideal for 3D printing beginners. It also comes in a range of colors, finishes, and diameters, providing a wide variety of options for creative projects.

    PLA is a widely available filament that can generate quality prints with minimal warping and shrinkage. It is also odorless and does not require a heated bed, which is why it is popular among 3D printing enthusiasts. However, not all filaments are created equal. The following are some of the most important considerations to look for in PLA filaments to ensure optimal performance and print quality:

    1. Diameter

    The filament’s diameter can affect the thickness of each layer of the print, and inconsistencies in diameter can cause uneven layers or gaps. PLA filaments typically come in two standard sizes: 1.75 mm and 3 mm. Choosing the incorrect diameter can lead to several issues, including under-extrusion or over-extrusion.

    Under-extrusion happens when the diameter is too large for the printer’s extruder, causing the filament to become trapped and inhibit proper extrusion. On the other hand, over-extrusion occurs when the diameter is too small for the extruder. This causes the printer to extrude too much material, resulting in a stringy and messy print.

    It is also crucial to remember that the diameter of PLA filament can vary across manufacturers and even between batches of the same brand. As a result, it is critical to check the diameter frequently. Adjusting the 3D printer’s settings is also recommended to ensure consistent and accurate prints.

    2. Color

    The filament’s color can affect the overall appearance and aesthetic of the 3D print. For example, a 3D model with a natural or translucent filament will look different from a bold, bright color. However, it is essential to consider that the color can affect the printing process and the final quality of the print.

    Filaments with darker colors, such as black, need higher printing temperatures. If they are not printed at the right temperature, it could lead to clogging or under-extrusion. Meanwhile, lighter-colored filaments need low temperatures and can be more tolerant if printed at slightly lower temperatures. In addition, the quality of the pigment utilized in the coloration process can impact its quality.

    3. Compatibility

    Not all filaments are suitable for every printer, and using an incompatible component can cause clogging under-extrusion or even damage to the machine. Compatibility is often determined by the diameter of the PLA filament and the printer’s extruder system. For example, some printers have different extruder systems, such as a direct-drive or Bowden extruder.

    One way to ensure compatibility is to choose PLA filament from the same manufacturer as the printer. This can help ensure it is designed to work well with the printer’s system and will minimize the risk of printing issues.

    4. Price

    PLA filament is generally more affordable than other 3D printing filaments such as ABS or PETG. This makes it an attractive choice for those on a budget or those experimenting with 3D printing. However, it is important to remember that the price can vary depending on its quality, color, and manufacturer. For instance, higher-quality filaments — such as those with tighter tolerances — can be more expensive but produce better results.

  8. What To Look For in ASA Filaments

    Leave a Comment
    Click to ExpandWhat-To-Look-For-in-ASA-Filaments

    ASA filaments are thermoplastic polymers that blend the properties of acrylonitrile, styrene, and acrylate. They have a glossy finish and come in a variety of colors. Moreover, they’re similar to ABS filaments but offer superior weather and UV resistance. They also have a high melting point, making them suitable for printing high-temperature parts.

    Choosing the right ASA filament for your 3D printing project can be complex. With an overwhelming number of options available, it can take time to determine which filament best fits your needs. To help you, here are the essential factors to consider:

    1. Print Temperature Range

    ASA filaments have a higher printing temperature range than PLA and ABS filaments, typically 230–260 °C. Therefore, choosing a filament with a suitable temperature range for your 3D printer is essential to ensure that your prints are successful. Additionally, these filaments are temperature-sensitive, meaning they may require a heated bed or enclosure to print correctly.

    2. Print Bed Adhesion

    These filaments tend to shrink and warp, resulting in the print detaching from the bed or distorting during the process. To prevent this, you can use adhesive sprays or specialized bed sheets to improve adhesion. Maintaining a level and clean print bed is crucial to ensure optimal adhesion before initiating printing.

    3. Diameter and Tolerance

    Choosing a filament with an appropriate diameter for your 3D printer’s extruder is essential. If the filament diameter is too small, it may cause under-extrusion and gaps in your print. Conversely, if the diameter is too large, it can cause over-extrusion and lead to clogs in your extruder.

    Furthermore, the tolerance of the filament refers to the deviation from the stated diameter. Therefore, choosing a filament with a low tolerance can ensure consistency in your prints.

    4. Filament Color and Finish

    The color and finish of your ASA filament can impact the final aesthetic appeal of your 3D prints. While color may not be a significant concern for functional parts, it can be essential for decorative items. In addition, certain applications may require specific finishes, such as matte or glossy.

    5. Cost

    When comparing the cost of ASA filament to other filaments, it’s important to consider the price per unit of volume rather than just the overall cost of the spool. Some brands may offer larger spools at a higher cost, but it may not necessarily be more cost-effective than a smaller spool from a different brand.

    It’s also important to consider the overall cost of 3D printing, including the cost of the 3D printer, maintenance, electricity, and other associated costs. ASA filament may cost more, but it’s worth considering if you need its specific properties for your project. In the long run, it could save you time and money.

  10. Terrafilum® & Ecologic® Announce Terrafilum Ecologic ABS Filament

    Leave a Comment

    Terrafilum® Engineered Filaments is proud to announce its new biodegradable Terrafilum® & EcoLogic® ABS Eco-One® filament.

    Terrafilum® Engineered Filaments ( is a US company that provides 3D printer filament solutions that intersect manufacturing, technology, and sustainability priorities of the 3D Printing and Additive Manufacturing Industry. The company was formed in response to its owner’s, Chris Jackson, observations of the common frustrations that manufacturers face when it comes to leveraging 3D printing technologies.

    “We address 3D printing’s sustainability issue by developing industrial-grade filaments that are made of bio-friendly and re-purposed materials. We are thrilled to be partnering with Ecologic® to produce quality ABS filament with enhanced landfill biodegradation,” Jackson stated. The addition of Eco-One® in our products helps reduce overall landfill space amounts required currently for plastic products by reducing the millions of tons of plastic that would otherwise sit for years on end. The organic biodegradation of Terrafilum ABS Eco-One®filaments produces valuable biogas that landfills can recapture to convert to electricity and alleviate our demand on traditional energy sources. You can learn more at the EPA’s Landfill Methane Outreach Program (

    Through systematic chemical and biological processes in a microbe-enriched, well-controlled landfill, Eco-One® enhances plastic biodegradation into biogas which can be converted into energy, carbon dioxide, and inert humus that enriches the soil. ASTM D5511 tests that represent biologically active landfills on Terrafilum ABS Eco-One®filaments have shown 8.11% biodegradation in the first 60 days.

    Using lean principles, Terrafilum® custom engineers complete solutions — from material to spool design and always striving for zero percent waste — bringing value to their customers with material quality that assures smooth printing operations. Terrafilum®solutions are available in a wide selection of colors, sizes, and materials. Support of custom projects and applications is central to the company’s core philosophy for customer needs.

    ”We are very pleased to have a strong relationship with Ecologic® which is supported by other market leaders in fiber and apparel, footwear, flexible and rigid packaging, foam, sporting goods, and much more. Terrafilum® is constantly researching the development of filaments with the planet as our main concern,” Jackson commented.

    The introduction of Eco-One®’s organic additive enhancing the biodegradability of Terrafilum® ABS filament without compromising on the filament’s integrity during manufacturing, storage, and use, as well as no evidence of adverse effects on printing or other post-processes, is one of the many positive aspects to the additive’s performance.Eco-One®’s addition to our products does not change the manufacturing process. Additionally, the organic additive has no effect on the plastic’s chemical or physical properties, rendering the filament with the same tensile strength and identical performance. With all these wonderful attributions to our filament, we are excited about our partnering with EcoLogic® to provide you with an industrial-grade ABS filament that aligns with Terrafilum®’s values of sustainability.

    “It’s a great time for EcoLogic® as we step into the 3D Printing world! Terrafilum® is a leader in 3DP Innovation and we are excited to see what the Terrafilum® team can achieve with the Eco-One® technology. The Terrafilum® ABS Eco-One®filament represents our passion for technology & science. We hope to inspire others and spark some curiosity about how we can all make a difference,” Michael Zuppa, Business Development Engineer at Ecologic® stated.

    EcoLogic® owns, manufactures, and markets the Eco-One® brand of additives for plastic products worldwide. You can learn more at
