Who it fits
Good fit for
You should choose this filament if you need durable parts for outdoor exposure. It suits makers who print automotive accessories, equipment housings, or garden brackets that face sun and rain. The strict diameter control helps users with longer projects avoid tangling or flow issues. It is also a good fit for those with enclosed printers like Bambu Lab X1, P1S, or Creality K1 series, as these setups provide the necessary temperature stability for ASA printing.
Who should skip it
You should look elsewhere if you plan to print small decorative items that do not need weather resistance. This filament requires a nozzle temperature between 240-270°C and a heated bed at 70-95°C, which may be too much for basic open-frame printers. You should also skip this if you prefer high-speed printing, as the recommended speed is only 30-50mm/s. Additionally, if you do not have an enclosed chamber, you may struggle with warping despite the material's general stability.
Verdict: This ASA filament is a solid choice for functional, weather-resistant prints when paired with the right enclosed printer settings. Its tight tolerances and UV resistance make it reliable for demanding outdoor applications.
Key specs explained for IEMAI ASA
Material Type: ASA
Acrylonitrile styrene acrylate offers strong resistance to UV light and weather. You get parts that hold their shape and color outside. This material is tougher than PLA and more weatherproof than ABS. It suits garden tools, automotive brackets, and outdoor fixtures that face sun and rain daily.
Filament Diameter: 1.75mm
This standard width fits most FDM 3D printers. It ensures smooth feeding into the extruder without jams. You avoid clogs and inconsistent flows that ruin prints. Check your printer compatibility list to confirm it accepts this size before buying, as some older models use different diameters.
Dimensional Accuracy: +/- 0.02mm
Strict diameter control means the filament feeds consistently. You get stable extrusion and fewer print failures. This tolerance reduces gaps or blobs in your layers. Compare this to cheaper filaments with wider variances, which often cause feeding issues and require frequent manual adjustments during long prints.
Net Weight: 1kg
Each spool contains one kilogram of material. This size handles medium to large functional parts. You get enough plastic for multiple prototypes or sturdy brackets. Larger projects might require two spools. Consider your typical print size to decide if this single spool meets your monthly production needs.
Max Print Speed: 50mm/s
The recommended speed balances quality and time. You get strong layers without sacrificing detail. Printing faster may weaken impact resistance or cause warping. This limit ensures the material bonds properly. Compare this to PLA speeds, which often run higher. Use this guide to set your slicer for best results.
Design and build details
According to the listing, this IEMAI ASA filament is a 1.75mm thermoplastic designed for durability. The material type is ASA, which provides strong resistance to UV light and weather. You get parts that hold their shape and color outside. This material is tougher than PLA and more weatherproof than ABS. It suits garden tools, automotive parts, and functional prototypes that face outdoor conditions. The marble color option gives a textured finish that may help hide minor surface imperfections during printing.
The spool contains 1kg of material, with a total package weight of 2.2 pounds. The filament maintains a dimensional accuracy of +/- 0.02mm, ensuring consistent feeding and stable extrusion. This tight tolerance helps reduce tangling and uneven flow during longer prints. The recommended print speed is up to 50mm/s, allowing for reasonable production times without sacrificing layer adhesion. You should print at nozzle temperatures between 240-270°C and bed temperatures between 70-95°C.
Each spool is vacuum sealed with desiccant to protect against moisture. This packaging helps maintain material integrity before you open it. The filament is compatible with most enclosed 1.75mm FDM 3D printers. You should keep the cooling fan off or at a low setting to reduce warping. Using a suitable bed adhesive is also recommended for better layer adhesion. The neat winding helps prevent printing interruptions during extended projects.
Setup and everyday use
You begin by unloading the vacuum-sealed spool. The listing notes that each spool is dried before packaging and includes desiccant to protect against moisture and dust. This packaging helps maintain filament quality until you load it into your printer. The IEMAI ASA filament is compatible with most enclosed 1.75mm FDM 3D printers. This includes models from Bambu Lab, Creality, and QIDI, provided they support high-temperature operations. You must ensure your printer can reach the required nozzle temperatures.
For daily printing, you set your nozzle temperature between 240 and 270°C. The heated bed should be set between 70 and 95°C. You should keep the printing speed between 30 and 50mm/s. To achieve better layer adhesion and reduce warping, you must print inside an enclosed chamber. You also need to keep the cooling fan off or at a low setting. Applying a suitable bed adhesive is recommended when necessary.
The +/- 0.02mm dimensional accuracy ensures consistent feeding. This tight tolerance helps prevent tangling and uneven flow during longer projects. The neatly wound spool supports stable extrusion. You can use this filament for functional outdoor parts like garden accessories, equipment housings, and automotive components. The material resists sunlight, rain, and temperature changes. You get durable parts that maintain their strength and shape over time. The Marble color option is one of several available variations.
Before you buy IEMAI ASA
You need an enclosed printer for this material. The listing recommends an enclosed chamber to reduce warping and improve layer adhesion. Open-frame printers may struggle with the recommended bed temperature of 70-95°C. You should also verify your printer’s nozzle can handle 240-270°C. Most high-temperature FDM printers, including Bambu Lab X1 and P1S series, work well. Keep the cooling fan off or low during printing. This filament sits alongside other durable options like ABS or PETG in your toolkit. It suits outdoor functional parts better than standard PLA. You must store the spool in a dry box after opening. The vacuum seal helps, but moisture absorption will still occur over time. Check your printer’s compatibility with 1.75mm filament diameter. Ensure your extruder gears can handle the feed rate of 30-50mm/s. This material is for durable prototypes, not decorative displays.
Check before you buy
- Confirm your printer has an enclosed chamber for heat retention
- Verify nozzle temperature supports up to 270°C for safe extrusion
- Ensure bed temperature reaches at least 70°C for proper adhesion
- Check that your extruder handles 1.75mm filament without slipping
- Prepare a dry storage box to prevent moisture absorption
