Who it fits

Key specs explained for UJOY3D

Net Weight: 4kg

This bundle contains four spools, each weighing 1kg, for a total of 4kg. This provides a substantial supply for extended projects without frequent reordering. You save time on setup by having multiple spools ready. This weight is ideal for users who print regularly and want to maintain a steady workflow without interruption for refills.

Material Type: PLA+

PLA+ is an enhanced version of standard PLA, offering improved durability and flexibility. It resists brittleness better than regular PLA, making prints less likely to snap under stress. This material suits functional parts, prototypes, and everyday items. You get a balance of ease of use and stronger results compared to basic PLA filaments.

Max Print Speed: 400 mm/s

The filament is optimized for high-speed extrusion, supporting speeds up to 400 mm/s. This allows faster completion of prints without sacrificing layer adhesion or surface quality. You benefit from reduced print times, especially for large or complex models. This spec is key for users with high-speed printers who want to maximize their machine's potential.

Filament Diameter: 1.75mm

This is the standard diameter for most FDM 3D printers. It ensures compatibility with a wide range of extruders and hotends. You do not need to adjust feeder gears or nozzles for fit. This universal size makes it a safe choice for new users or those with multiple printer brands.

Dimensional Accuracy: ±0.03mm

The filament thickness varies by no more than 0.03mm from the nominal 1.75mm. This tight tolerance ensures consistent extrusion flow, reducing under-extrusion or clogging issues. You get uniform layer heights and better dimensional accuracy in your prints. This precision is critical for detailed models and parts requiring tight fits.

Design and Build Quality

According to the listing, this bundle uses premium refined corn-based raw materials. The manufacturer states the formula is optimized for high-speed printing, which should deliver smoother extrusion and consistent results. You get four 1kg spools, totaling 4kg of Elite PLA+ filament. Each spool maintains a 1.75mm diameter with a dimensional accuracy of ±0.03mm. This tight tolerance ensures the filament fits universal standard spool sizes, allowing compatibility with most mainstream FDM 3D printers. The packaging is vacuum-sealed with desiccant to isolate moisture. This design choice helps keep the filament dry during transit or long-term storage, preserving printing quality. The listing notes the use of 100% virgin new raw materials. This formulation aims to eliminate recycled impurities, resulting in stable properties and low odor. You benefit from a pure material that supports steady printing quality from batch to batch. The spools feature a standard layout that prevents tangling or knotting. This physical design reduces the risk of nozzle clogging during extrusion. The glossy finish and uniform color tone are highlighted for their anti-fading properties. You can expect stable color display and full surface effects during long prints. The bundle includes popular vibrant colors like black, red, orange, and yellow. This variety allows you to choose specific hues for daily or creative projects. The design prioritizes continuous printing stability. You save time and materials by reducing failed prints. The high-speed capability supports printing speeds up to 400 mm/s. This allows for faster production cycles without sacrificing the fine shaping typical of PLA+ materials.

Setup And Everyday Use Guide

You load four 1kg spools into your printer. The listing confirms universal standard spool size, so they fit most mainstream FDM 3D printers without modification. You do not need to adjust the spool holder for compatibility. Each spool is individually vacuum sealed with desiccant. You remove the packaging and desiccant before loading. This keeps the filament dry during transit and storage. You should store unused spools in a dry place to maintain quality.

The recommended print settings are straightforward. You set the nozzle temperature between 205°C and 220°C. Use 210°C for the first layer. The heated bed should be set between 55°C and 65°C. These settings support a wide speed range. You can print at speeds up to 400 mm/s. The ±0.03mm dimensional accuracy suggests consistent extrusion. This reduces failed prints and saves material.

Daily use involves loading the spool and starting the print job. The formula uses 100% virgin raw materials. This should result in low odor and stable properties. You get smooth extrusion with no tangling or knotting. The bundle includes vibrant colors. You can choose from various color combinations. The anti-fading property helps maintain color tone. You get a glossy surface effect. This bundle suits daily creative projects and functional parts. You benefit from reduced clogging and stable continuous printing.

Before You Buy This Bundle

This bundle contains filament, not a printer. You need an FDM 3D printer to use these spools. The listing notes universal standard spool size, which fits most mainstream machines. You should verify your printer’s filament diameter input matches the 1.75mm specification. The recommended print settings suggest a nozzle temperature between 205–220°C and a bed temperature of 55–65°C. Your printer must support these temperatures. The max print speed is 400 mm/s. You should check if your machine can handle this high-speed extrusion without skipping steps or degrading quality. The vacuum packaging keeps the filament dry. You must store it in a dry place after opening. If your printer lacks a dry box, moisture may affect print quality over time. This bundle suits users who already have compatible hardware and want high-speed printing capabilities. It does not replace a printer. It complements existing tools by providing a steady supply of material for extended projects.

Check before you buy

• Verify your printer supports 1.75mm filament diameter.
• Check if your printer reaches 220°C nozzle temp.
• Ensure your printer handles 400 mm/s speeds.
• Confirm your printer uses standard spool sizes.
