Polymaker vs IEMAI PETG Specs
Print speed
When you look at maximum print speeds, IEMAI takes the lead. Its transparent orange PETG filament supports speeds up to 600mm/s. This allows for faster production of functional parts and decorative items without sacrificing surface quality. Polymaker’s high-speed PETG filament also offers impressive performance, but it caps at 500mm/s. While both filaments are designed for rapid extrusion and smooth flow, the extra 100mm/s on the IEMAI spool gives you a clear advantage in throughput. If your printer can handle high speeds and you need to produce parts quickly, the IEMAI option provides a faster ceiling for your projects.
Dimensional accuracy
Precision matters for consistent feeding and reliable prints. IEMAI specifies a strict dimensional accuracy of +/- 0.02mm for its 1.75mm filament. This tight tolerance helps minimize clogging, stringing, and layer adhesion issues during printing. The data for Polymaker does not list a specific diameter tolerance value. Without this published specification, you cannot verify if its consistency matches the tight controls of the IEMAI product. For users who require precise fitment or want to avoid feeding issues in direct-drive extruders, the stated accuracy of IEMAI offers a measurable benefit over the unspecified tolerance of Polymaker.
Finish and transparency
The visual result of your print depends heavily on the filament finish. IEMAI offers a transparent orange variant that delivers crystal-clear, glass-like transparency. This makes it ideal for lampshades, light covers, or decorative parts where light transmission is key. Polymaker provides a standard white finish that results in a smooth, refined texture with a clean appearance. However, it is opaque. If you need clear parts for aesthetic or functional light-diffusing purposes, IEMAI is the only choice here. Polymaker is better suited for solid, opaque models where surface smoothness is the priority.
Color options
Both brands offer a range of colors, but the variety differs. Polymaker lists eight specific colors for its 1kg spools, including white, purple, red, lime, magenta, dark grey, black, and blue. These are solid, opaque colors. IEMAI focuses on transparent and gradient options. Its variations include transparent orange, transparent blue with red, transparent fluorescent green, and several gradient mixes like blue-white or blue-purple. If you prefer standard solid colors for general prototyping, Polymaker has a broader selection. If you want translucent or gradient effects for special projects, IEMAI provides unique aesthetic options that Polymaker does not offer.
Material properties
Both filaments are made from PETG, combining the ease of PLA with the durability of ABS. They both offer high impact resistance, toughness, and flexibility. Polymaker highlights its suitability for functional components and sturdy models that withstand mechanical stress. IEMAI emphasizes its heat resistance and interlayer adhesion, noting strong bed adhesion to minimize warping. Since both products share the same base material type and general mechanical benefits, they are well-matched for everyday use. Neither has a distinct advantage in the core material science, as both deliver reliable strength and durability for functional prints.
Which PETG filament should you buy
Users needing crystal clear decorative parts
IEMAI offers a transparent orange finish with excellent light transmission. This glass-like transparency is ideal for lampshades, light covers, and display models. The high-speed printing capability supports 600mm/s, allowing you to produce these decorative items quickly while maintaining a smooth surface and stable extrusion.
Printers prioritizing maximum speed and durability
Polymaker supports high-speed printing up to 500mm/s with enhanced fluidity. It combines the ease of PLA with the toughness of ABS. This filament provides excellent impact resistance and durability for functional parts. You get smooth feeding and consistent extrusion for everyday models and sturdy prototypes.
Users requiring tight dimensional accuracy
IEMAI specifies a strict dimensional accuracy of +/- 0.02mm. This precision ensures smooth feeding and consistent extrusion, minimizing issues like clogging and stringing. The strong bed adhesion helps reduce warping and shrinkage, which is critical when you need reliable print results for precise functional components.
