Who it fits
Good fit for
You should choose this filament if you print functional prototypes or automotive parts that require heat resistance. The high speed rating suits makers who want to reduce print times for medium-sized objects. The bundle includes four distinct colors, which helps if you need variety for visual models or color-coded components. The standard spool dimensions fit most FDM printers, so you do not need special adapters. If you value toughness and fast turnaround, this ABS blend meets those needs.
Who should skip it
Skip this product if you require a single solid color for every project. This bundle mixes black, white, blue, and red, which prevents consistent coloring across multiple prints. You should also avoid it if your printer cannot handle speeds above 200mm/s, as the recommended settings start at 300mm/s. Additionally, if you need materials with lower warping tendencies than standard ABS, this may not be the best fit. The high nozzle temperature requirement of 280-290°C also limits compatibility with some older or smaller printers.
Verdict: This bundle offers high-speed ABS printing with good heat resistance for functional parts. It is a practical choice for users who need speed and durability in mixed colors.
SUNLU 4kg High Speed ABS Key Specs
Max Print Speed 350mm/s
This specification indicates the filament can be extruded at high rates without compromising layer adhesion. You can set your printer to output up to 350mm/s, which significantly reduces the time required for large or complex models. This speed is ideal for users who prioritize rapid production cycles and need to finish projects quickly. It supports a balanced approach between velocity and consistent print quality.
Heat Deformation Temperature 91°C
This value defines the thermal stability of the printed parts. Your prints can withstand ambient temperatures up to 91°C before softening or deforming. This makes the material suitable for functional components used in automotive interiors or machinery that may experience heat. It offers better durability in warm environments compared to standard ABS, ensuring your parts remain intact during long-term use.
Material Type ABS
Acrylonitrile Butadiene Styrene is a durable thermoplastic known for its toughness and impact resistance. This material is well-suited for mechanical parts, molds, and toys that require structural integrity. It provides a good balance of strength and flexibility, allowing parts to absorb pressure without breaking. ABS is a standard choice for general-purpose manufacturing and prototyping tasks where reliability is essential.
Net Weight 1KG
Each spool contains one kilogram of filament, which typically yields approximately 330 feet of 1.75mm thread. This weight is the standard unit for measuring filament volume, helping you estimate how many small prints or a few large models you can produce. It allows for easy inventory tracking and ensures you know exactly how much material is available for your upcoming projects.
Design and Build Analysis
According to the listing, this filament bundle contains four 1kg spools of ABS plastic. The package size is listed as 4kg, with a total weight of 8.82 pounds. The material type is specified as ABS, which is known for its durability and heat resistance. The listing notes a heat deformation temperature of up to 91°C, making it suitable for high-temperature applications. It also highlights impact strength and toughness, suggesting the printed parts can withstand pressure without deforming.
The spools are designed with a diameter of 20cm, a width of 6.8cm, and a hub hole diameter of 5.5cm. These dimensions are intended to fit most FDM 3D printers. The listing claims a 100% neat winding rate, which aims to reduce the risk of tangles and jams during printing. This layout supports smoother operation, especially at higher speeds.
The color options include black, white, Klein Blue, and red in the 4kg bundle. The listing recommends a nozzle temperature of 280-290°C and a bed temperature of 90-100°C. These settings, combined with the 350mm/s speed capability, are designed for efficient production. The build quality focuses on consistent extrusion and reliable performance across various fields, including machinery and automotive parts.
Setup And Everyday Use
Setting up this filament requires matching its physical dimensions to your printer’s extruder system. The listing specifies a spool diameter of 20cm, a width of 6.8cm, and a hub hole diameter of 5.5cm. These measurements are designed to fit most standard FDM 3D printers. You can hang the reusable spool directly on your machine without needing adapters. The packaging includes four separate 1kg spools, which means you must load each one individually if you plan to use different colors in a single print job. The filaments are wound neatly, which the manufacturer states reduces the risk of tangles or jams during feeding. This neat winding supports a smoother extrusion process as you switch between the black, white, Klein Blue, and red spools.
For daily use, the product is engineered for high-speed output. You can set your printer to operate at speeds up to 350mm/s. The listing recommends a nozzle temperature between 280°C and 290°C, and a bed temperature between 90°C and 100°C for optimal results. These settings allow you to maintain a balance between speed and print quality. The ABS material offers heat resistance up to 91°C, making it suitable for parts that will face warm environments. Its durability ensures the printed items remain intact even after long-term use. The filament also provides good impact strength, allowing parts to withstand pressure without deforming or breaking easily. This makes it a practical choice for functional items like machinery parts, molds, or automotive components. The balanced mechanical properties support various applications, from toys to more demanding industrial uses. You simply adjust your slicer settings to match the recommended parameters and begin printing.
Before You Buy This ABS Bundle
Owning this bundle means managing four distinct spools rather than one continuous roll. You need to ensure your printer’s extruder can handle the weight of each 1kg spool without slipping. The listing notes a neat winding rate, which helps prevent tangles, but you should still inspect the filament for dust before loading. Since the material is ABS, you must verify your enclosure can maintain the recommended bed temperature of 90-100℃. High speeds up to 350mm/s require stable firmware and precise calibration. This product fits alongside other high-volume options if you prioritize speed and durability over single-color simplicity. Check that your nozzle temperature range supports 280-290℃ for optimal adhesion. You may also need additional spool adapters if your printer’s hub diameter differs from the specified 5.5cm. Regular cleaning of the drive gears is advisable to maintain consistent feed rates at high speeds.
Check before you buy
- Verify your printer’s extruder can handle 1kg spool weights.
- Confirm your enclosure maintains 90-100℃ bed temperature.
- Check if your nozzle supports 280-290℃ operating range.
- Ensure your hub diameter matches the 5.5cm specification.
- Inspect filament surface for dust before first use.
