Specifications side by side

IEMAI Filament Lineup Overview

IEMAI offers five spools in 1KG sizes, sorted by material type and finish. The PETG options include a transparent orange model for durable, clear parts and a red variant optimized for high-speed functional printing. Both use 1.75mm diameter filament.

For rigid applications, the lineup features a matte black PLA-CF carbon fiber option for stiff parts without an enclosed chamber. The ABS white filament provides industrial-grade toughness for heat-resistant needs. Finally, the yellow ASA filament delivers weather resistance for outdoor functional components and automotive accessories.

IEMAI Range Suitability Guide

IEMAI suits makers who need specific material properties for functional parts. You have PETG for clarity and speed, PLA-CF for stiffness, ABS for heat resistance, and ASA for outdoor durability. All listed spools are 1KG with 1.75mm diameter. The range covers transparent, matte, and standard finishes. You lack options for flexible materials, metallics, or larger 2KG spools in this selection. This brand fits users who prioritize engineering-grade performance over aesthetic variety. If you need multi-color printing or specialized filaments like TPU, this lineup does not provide them. Stick to these five choices for reliable, durable outputs.

How to choose IEMAI filament

1. Match material to use

   Select the polymer based on your part’s end use. IEMAI offers PETG for impact resistance and clarity, ideal for transparent functional items. Choose PLA-CF if you need engineering-grade stiffness with a matte finish, suitable for rigid components without an enclosed chamber. ABS provides industrial toughness for heat-resistant applications, while ASA delivers weather resistance for outdoor parts. You must align the material type with the mechanical and environmental demands of your project to ensure durability.

2. Check print speed needs

   If you prioritize faster production times, look for filaments explicitly labeled for high-speed performance. The red PETG variant is optimized for high-speed functional part printing, allowing you to maintain dimensional accuracy while extruding quickly. Standard PETG and other materials may require slower speeds to prevent defects. You should verify the speed rating in the product specifications before purchasing, as this directly impacts your workflow efficiency and the consistency of your final prints.

3. Consider enclosure requirements

   Your printer’s enclosure status dictates which materials will succeed. ABS and ASA require enclosed chambers to manage high nozzle temperatures and prevent warping due to cooling issues. PLA-CF is noted as suitable for users who do not have an enclosed chamber, making it more accessible for open-frame printers. PETG is versatile but benefits from controlled environments. You must ensure your printer setup matches the thermal requirements of the chosen filament to avoid print failures.

4. Evaluate finish aesthetics

   Choose your filament based on the desired surface appearance of the final object. Transparent PETG offers clarity, making it perfect for decorative items or parts where visibility is key. PLA-CF provides a distinct matte black finish, giving functional parts a professional, non-reflective look. Standard ABS and ASA come in solid colors like white and yellow. You should inspect the finish specification to ensure it meets your visual standards for the specific application.

5. Verify spool weight

   All IEMAI filaments in this guide are packaged in 1KG spools. This consistent weight allows you to calculate material usage accurately across different materials like PETG, ABS, and PLA-CF. Each spool weighs approximately 2.2 pounds, including the packaging. You do not need to adjust your material budget calculations for different product types, as the mass remains uniform. This standardization simplifies inventory management and cost estimation for your printing projects.
