Who it fits

Key specs for this PLA filament

Filament Diameter: 1.75mm

This is the standard thickness for FDM 3D printers. You can use this filament in almost any desktop printer. It fits the extruder gears and hotends designed for this size. If your printer uses 2.85mm filament, this product will not work. Stick to 1.75mm for broad compatibility and easy loading.

Dimensional Accuracy: +/- 0.02mm

This tight tolerance means the wire thickness varies very little. Consistent diameter prevents clogs and under-extrusion. Your printer extrudes the right amount of material every time. This accuracy ensures smooth layers and strong parts. Check this spec when buying filament to avoid print failures caused by uneven flow.

Material Type: PLA

Polylactic Acid is a biodegradable plastic made from renewable resources. It prints at lower temperatures than ABS or PETG. PLA is easy to use and produces minimal warping. It is ideal for beginners and detailed models. Choose PLA for prototypes, toys, and decorative items that do not need high heat resistance.

Net Weight: 1KG

This spool contains one kilogram of filament. It provides a substantial amount of material for various projects. You can print many small items or one large object. This size is manageable for storage and shipping. Compare this weight to other spools to estimate your printing volume and budget for future purchases.

Max Print Speed: 100mm/s

The manufacturer recommends printing up to 100 millimeters per second. This speed balances quality and efficiency. You can increase speed for rough drafts or decrease it for fine details. Faster speeds reduce print time but may affect surface finish. Adjust your slicer settings based on this recommendation for optimal results.

Design and build of SUNLU PLA

According to the listing, this SUNLU PLA filament comes in a black finish. The material type is listed as standard PLA, which is known for being versatile and easy to use. This choice of material makes it suitable for beginners and experienced users who want reliable prints. The filament is wound neatly on a spool, which reduces the risk of tangles and jams during printing.

The spool dimensions are specific: it measures 8.00 inches in diameter and 2.50 inches in width. The hub hole diameter is 2.20 inches. These sizes are designed to fit most FDM 3D printers. The net weight of the filament is 1KG. The overall package weighs 2.21 pounds, with dimensions of 8.66 inches by 8.66 inches by 3.15 inches. This compact packaging allows for easy storage on printer shelves or in supply cabinets.

The filament diameter is 1.75mm with a dimensional accuracy of +/- 0.02mm. This tight tolerance ensures smooth feeding into the extruder. You can use this filament in almost any desktop printer that accepts 1.75mm material. The neat winding process helps maintain consistent extrusion, which supports high-quality layer adhesion. This design choice means you can expect fewer clogs and a smoother printing experience. The spool is built to hang on many common printer models, keeping your workspace organized and your prints consistent.

Setup and Daily Use Guide

Loading this filament into your printer is straightforward. The spool measures 8.00 inches in diameter, 2.50 inches in width, and has a 2.20-inch hub hole. These dimensions fit most standard FDM 3D printer filament holders. You simply place the spool on the holder and thread the 1.75mm filament through your extruder. The listing notes a 100% neat winding rate, which reduces the risk of tangles or jams during the loading process. This neat winding helps ensure a smoother feed into the printer mechanism.

For daily printing, the manufacturer recommends specific settings to achieve the best results. You should set your nozzle temperature between 200°C and 230°C. The bed temperature should be maintained between 50°C and 65°C. You can print at speeds ranging from 50mm/s to 100mm/s. The dimensional accuracy of +/- 0.02mm ensures consistent extrusion, which supports these speed ranges without causing clogs. This consistency helps maintain high-quality layer adhesion.

This black PLA filament is compatible with almost all 1.75mm FDM 3D printers. Its wide compatibility means you do not need to adjust your printer hardware for this material. The 1KG net weight provides a substantial amount of material for your projects. You can rely on the specified parameters to guide your slicing software settings. This approach minimizes trial and error, allowing you to focus on your design rather than troubleshooting feed issues. The straightforward setup and clear recommended settings make this filament suitable for both beginners and experienced users seeking reliable performance.

Before You Buy This Filament

Owning this SUNLU PLA filament requires a few basic preparations. You will need a compatible FDM printer that accepts 1.75mm diameter material. Check your extruder gears and hotend specifications to ensure they handle this size correctly. The spool dimensions are 8.00 inches in diameter, 2.50 inches wide, with a 2.20-inch hub hole. Verify these fit your printer’s filament holder or stand. While the listing highlights neat winding to reduce tangles, proper storage is still key. Keep the spool in a sealed bag with desiccant to maintain quality. This filament is one of 1 options available in this category. It suits beginners and experienced users alike due to its ease of use. Recommended settings include a nozzle temperature of 200-230°C and a bed temperature of 50-65°C. These parameters help achieve smooth layer adhesion. Always consult your printer’s manual for specific bed surface requirements. This guide covers only the published specifications. It does not reflect individual testing results or personal experiences. Your results may vary based on your machine and environment.

Check before you buy

• Verify your printer accepts 1.75mm filament diameter.
• Check spool hub hole size is 2.20 inches.
• Ensure your filament holder fits the 8-inch diameter.
• Confirm bed surface compatibility for PLA printing.
