3D Printer Filament Creality SOLEYIN ULTRA PLA 1.75mm Grey 1kg (3301010581)

Creality SOLEYIN ULTRA PLA 1.75mm Grey is a 1 kg spool of polylactic acid (PLA) filament formulated for FDM/FFF 3D printers that accept 1.75 mm filament. The grey material is intended for general-purpose printing, offering straightforward extrusion, good layer adhesion and dimensional stability for prototypes, hobby parts and visual models. This filament is compatible with a wide range of desktop and workshop 3D printers designed for standard PLA processing temperatures.

Advantages

This PLA filament provides reliable feeding and consistent diameter tolerance for stable printing results. Its formulation balances ease of printing with sufficient stiffness and surface finish, reducing stringing and warping under common printing settings. The neutral grey color delivers good visual contrast for detailing and post-processing, and the 1 kg spool size supports extended print runs without frequent spool changes.

Suitable for

• Prototyping and product concept models
• Hobbyist and educational projects
• Visual and display parts that require good surface appearance
• Functional parts with moderate mechanical demands

When it may not be suitable

PLA is a biodegradable thermoplastic with relatively low heat resistance compared with engineering plastics; it may deform if exposed to temperatures above typical room values or used in high-temperature environments. For applications requiring high impact resistance, prolonged outdoor exposure, or elevated thermal performance, alternative materials such as PETG, ABS or technical filaments may be more appropriate.

Key specifications

• Material: Polylactic acid (PLA)
• Diameter: 1.75 mm
• Spool weight: 1 kg
• Color: Grey
• Intended printing technology: FDM/FFF

How to use

Load the filament into a compatible 1.75 mm FDM/FFF 3D printer following the printer manufacturer’s filament loading procedure. Recommended print settings typically include a nozzle temperature in the range commonly used for PLA (consult your printer and filament guidance), a heated bed if available set to moderate temperatures or left off depending on adhesion, and standard print speeds suitable for your machine. Ensure the filament feeds smoothly from the spool and perform initial calibration prints to verify layer adhesion and dimensional accuracy before production runs.

What to consider before purchase

• Confirm your 3D printer supports 1.75 mm filament and PLA material
• Check recommended printing temperatures for PLA on your specific printer
• Consider whether the grey color and mechanical properties meet your project requirements
• Verify spool dimensions and mounting method fit your printer’s spool holder

Usage recommendations

For best results, store the filament in a dry place and use a filament dryer or sealed container with desiccant if printing in humid conditions. Start with conservative print speeds and standard PLA temperatures, then fine-tune retraction and cooling settings to reduce stringing and improve surface quality.
