PLA Pro 1.75mm Pre-Dried Filament Refill 21kg Pack - Black & White

Our review of the Inslogic Pre-Dried PLA Pro filament refill finds it best suited for makers and small workshops that need dependable, high-impact PLA with minimal moisture issues; the single biggest reason to buy is its factory pre-dried, vacuum-sealed packaging and automated winding, which together deliver consistent, bubble-free extrusion and reliable first-layer adhesion. This refill bundle combines two reusable spools and a total of 21kg of filament in core black and white, making it a practical choice for longer print runs without frequent spool changes.

Key Features

• Factory pre-dried: Filament is dried for six hours at the factory to remove moisture and reduce bubbles that cause nozzle clogs and poor first-layer adhesion.
• Impact-resistant formulation: PLA Pro offers ABS-like toughness and high impact resistance for more durable functional parts and prototypes.
• Fast printing capable: Supports printing speeds up to 300mm/s, helping reduce print time while maintaining improved layer adhesion for many models.
• Jam-free winding: Automated winding and careful spool handling prevent tangles and ensure a smooth, clog-free feeding experience during long prints.
• Vacuum-sealed protection: Each refill arrives in 100% vacuum-sealed bags to keep filament dry and consistent until use.
• Wide compatibility: Precise 1.75mm +/-0.02mm diameter makes the filament compatible with most consumer and prosumer 3D printers, including Bambu, Prusa, and Anycubic.

Who It's For

This refill pack is aimed at hobbyists, educators, and small workshop users who value print reliability and need a mixture of black and white filament without constantly swapping spools. The emphasis on pre-dried material and a reusable spool system also appeals to customers who run longer print jobs or who have printers that are sensitive to moisture-related extrusion problems.

Users who prioritize specialty materials like TPU, high-temperature engineering plastics, or strictly food-safe certified filaments should look elsewhere, since this product is a PLA-based material intended for durability and general-purpose use rather than niche material properties.

Pros & Cons

Pros

• Pre-dried and vacuum-sealed packaging greatly reduces moisture-related print failures and bubbles.
• Good impact resistance gives printed parts more durability than standard PLA.
• Automated winding and reusable spools minimize tangles and make large jobs smoother.
• Compatible with a wide range of printers thanks to accurate 1.75mm diameter control.

Cons

• PLA-based material is not a substitute for high-temp engineering plastics when extreme heat resistance is required.
• Only two colors included in the bundle, which may not suit users needing many color options in a single order.

Frequently Asked Questions

Is this filament ready to print out of the bag?
Yes; the filament is factory pre-dried and vacuum-sealed, so it is ready to print once unsealed and loaded onto the spool.

Will this work on my consumer 3D printer?
It is compatible with about 99% of printers that accept 1.75mm filament, including many popular models like Bambu, Prusa, and Anycubic.

What print settings should I use?
Inslogic recommends a nozzle temperature of 195-205C and a bed temperature of 55-65C for best results.
