Who it fits
Good fit for
This filament suits makers who need to produce functional prototypes or end-use parts quickly. If your workflow involves machinery components, molds, or automotive parts, the high speed and heat resistance are practical assets. The 1kg pack size is ideal for small batch runs. Users with FDM printers that can handle 350mm/s speeds will benefit from the reduced print times. The sturdy ABS composition ensures parts withstand pressure and impact, making it a reliable choice for industrial or hobbyist applications requiring durability.
Who should skip it
You should look elsewhere if you require low-temperature printing or have an enclosed printer that struggles with ABS fumes. The recommended settings demand a nozzle temperature of 280-290°C, which may exceed the capabilities of some entry-level machines. If you prioritize ease of printing over speed, the high-speed requirements might lead to warping if your bed leveling is not precise. Additionally, if you need colors other than black, you must select a different variation, as this specific pack contains only black spools.
Verdict: This SUNLU filament offers a practical solution for users needing fast, durable ABS prints. It is well-suited for high-speed workflows and functional part production.
Key specs explained
Material Type: ABS
Acrylonitrile butadiene styrene offers strong, durable parts with good heat resistance. This material suits functional prototypes, mechanical components, and automotive parts. You get a balance of toughness and ease of printing. ABS is a standard choice for users needing rigid, long-lasting objects that can withstand moderate temperatures without deforming during use.
Max Print Speed: 350mm/s
This filament supports speeds up to 350mm/s, significantly reducing print times compared to standard materials. You can produce parts faster without sacrificing structural integrity. This benefit is ideal for users needing rapid iteration or high-volume output. It allows you to keep your printer running efficiently while maintaining consistent layer adhesion and surface quality.
Net Weight: 1KG, 2 Pack
You receive two spools, totaling one kilogram of filament. This bulk format provides more material for larger projects or extended printing sessions. It reduces the frequency of filament changes, which minimizes potential print failures caused by loading new spools. This option is practical for users who frequently print medium-to-large objects and want consistent material supply.
Heat Deformation Temperature: 91°C
The filament maintains its shape up to 91°C, offering robust thermal stability. This feature ensures your printed parts remain intact in warmer environments or under mild heat exposure. It is essential for automotive interior components or machinery parts that may face elevated temperatures. This resistance prevents warping or softening during everyday use in demanding conditions.
Design and Build Overview
According to the listing, this SUNLU filament is an ABS material engineered for high-speed FDM printing. The packaging contains two 1kg spools, totaling 2kg of black filament. This 2-pack format allows you to maintain longer print runs without frequent filament changes. The material itself is described as having high impact strength and toughness. It can withstand pressure without deforming or breaking easily. This durability makes it suitable for functional parts that face mechanical stress or long-term use. The ABS compound also offers heat resistance, with a deformation temperature up to 91°C. This thermal stability is useful for components exposed to moderate heat, such as automotive interior parts or machinery molds.
The filament is wound neatly on reusable spools with a 100% neat rate. This layout reduces the risk of tangles and jams during printing. The spool dimensions are standardized for compatibility. The diameter is 20cm, the width is 6.8cm, and the hub hole diameter is 5.5cm. These measurements fit most FDM 3D printers, allowing you to mount the spool directly on your printer’s holder. The total weight of the 2-pack is 4.41 pounds. This compact and standardized design ensures smooth feeding into the extruder. You get a consistent print experience without interruption from tangled filament or incompatible spool sizes. The build quality supports reliable performance at speeds up to 350mm/s.
Setup And Daily Use Guide
The SUNLU High Speed ABS filament is designed for straightforward integration into your existing FDM workflow. The spool dimensions are 20cm in diameter, 6.8cm in width, and feature a 5.5cm hub hole. These measurements align with the standard specifications for most FDM 3D printers, ensuring the spool fits securely on your printer’s filament holder without requiring adapters or modifications. You can hang the spool directly from the machine’s designated mount.
The listing emphasizes a 100% neat winding rate for each spool. This manufacturing detail implies a reduced risk of tangles or jams during feeding. A smooth, consistent filament path supports the high-speed performance claims by preventing friction-induced errors. You load the spool as you would with any standard ABS filament, relying on the neat winding to maintain steady extrusion.
Daily operation centers on the recommended printer settings. To achieve the advertised maximum speed of 350mm/s, you must configure your slicer and printer firmware accordingly. The listing specifies a nozzle temperature range of 280-290°C and a bed temperature between 90-100°C. These parameters are critical for activating the material’s full potential, including its heat deformation resistance up to 91°C and its impact strength.
Using this filament requires an enclosed or well-ventilated print area, as ABS is prone to warping if cooled too quickly. The high-speed capability allows you to produce durable parts for machinery, molds, or automotive applications faster than standard ABS. You benefit from the material’s toughness and stability, provided you adhere strictly to the thermal and speed guidelines. The 2-pack format ensures you have sufficient material for extended production runs without interruption.
Before You Buy This Filament
You should verify that your printer’s extruder can handle the recommended 350mm/s speed without skipping steps. Check that your build plate reaches at least 90°C for proper ABS adhesion. Since ABS warps easily, ensure your enclosure maintains a stable temperature near the 91°C heat deformation limit. You may need to adjust your slicer’s cooling settings, as high-speed ABS often requires minimal or no part cooling to prevent layer separation. Store the spools in a dry environment, as ABS absorbs moisture which degrades print quality. This filament fits into your workflow alongside other high-speed materials like PLA or PETG, but demands stricter thermal management. It suits users who prioritize throughput and part durability over delicate aesthetic finishes. Confirm your printer’s firmware supports the required feed rates. If you print large functional parts, this 2-pack offers consistent material properties for batch production. The neat winding reduces jam risks, making it a reliable choice for continuous operation.
Check before you buy
- Verify your printer supports speeds up to 350mm/s
- Ensure your bed reaches at least 90°C
- Check if your enclosure maintains stable heat
- Confirm your slicer settings for minimal cooling
- Store spools in a dry place
