PCTG (PolyCyclohexylene Dimethylene Terephthalate Glycol) is a close relative of PETG, but it offers better impact strength, clarity, and chemical resistance. It’s a copolyester that combines the ease of printing of PETG with the toughness and stability of engineering-grade materials. If you’ve printed PETG before, printing PCTG will feel familiar — but with improved mechanical performance and less brittleness.

PET-G vs PETG CF – what does carbon fiber add?

PET-G has become a trusted material for both beginners and advanced users. Known for its toughness, temperature resistance, and ease of use, PET-G strikes a balance between the printability of PLA and the durability of ABS. However, with the demand for stronger and more stable materials rising, filament manufacturers have introduced PETG CF, or Carbon Fiber–Reinforced PETG. By adding carbon fiber strands to PET-G, this material offers a new level of strength, stiffness, and professional-grade quality. But what exactly does carbon fiber change — and when is it worth using PETG CF over standard PET-G? Let’s explore this in depth.

PLA, PET-G, ASA – what’s the difference and which one to choose?

3D Printing offers a wide range of filament choices, each tailored to specific needs. Among the most popular are PLA (Polylactic Acid), PET-G (Polyethylene Terephthalate Glycol), and ASA (Acrylonitrile Styrene Acrylate). While all three are thermoplastics that melt and solidify during printing, their performance, durability, and ease of printing differ greatly. Choosing the right one depends on what you value most: ease of use, mechanical strength, or outdoor durability. This article explores each filament in depth, compares their properties, and provides guidance on when to use them.

Refill Spool Holder: A Practical Solution for Sustainable 3D Printing

One of the lesser-discussed challenges in 3D printing is the accumulation of empty filament spools. For hobbyists and professionals alike, these discarded spools can quickly pile up, taking up storage space and contributing to plastic waste. While many manufacturers design their spools from durable materials, the reality is that they are often not recycled or reused effectively. In response to this problem, the industry has introduced refill coils—spool-less filament bundles that minimize plastic use. To make these coils functional, a refill spool holder is used. This simple yet ingenious accessory not only reduces environmental impact but also enhances efficiency and convenience for everyday 3D printing.

Material Guide : HT-PLA

When it comes to 3D printing materials, one of the most well-known options is PLA (Polylactic Acid). Standard PLA is widely appreciated for its ease of printing, low warping, and eco-friendliness, but it does come with certain limitations—especially in terms of heat resistance and mechanical strength. This is where HT-PLA (High Temperature PLA) enters the picture. Engineered to address the shortcomings of regular PLA, HT-PLA offers a balance between printability and performance, making it a popular choice for users seeking functional, durable parts.

3D Printed Modular Hexagon: The Ultimate Pen Organizer & Multipurpose Container

Modern workspaces demands for tools that are not only functional but also adaptable, customizable, and visually appealing. Whether you’re working in an office, running a home studio, or simply trying to keep your desk tidy, the need for organization is universal.

Material Guide: PLA HS

In 3D printing, material choice plays a critical role in determining the quality, durability, and efficiency of your final product. Among the many options available, PLA HS—short for Polylactic Acid High-Speed

Comparing durable filaments: ABS, ASA, PC.

In the world of 3D printing, not all filaments are created equal; especially when it comes to durability and specific functionality. For engineers, hobbyists, and manufacturers seeking strength, heat resistance, and weatherproofing, three materials stand out: ASA (Acrylic Styrene Acrylonitrile), ABS (Acrylonitrile Butadiene Styrene), and PC (Polycarbonate)
