DEEPLEE Rapid PLA Plus Filament 1.75mm - High Speed PLA

In this review of the DEEPLEE Rapid PLA Plus Filament 1.75mm, the bottom line is clear: this filament is for makers who need reliable, high-speed printing without sacrificing part strength. It stands out when paired with a faster FDM machine, offering smooth extrusion and dimensional control that helps prints come out consistently. The biggest reason to buy is the combination of speed capability and toughness - users who want to push print speeds up to the hundreds of mm per second while keeping parts resistant to cracking will find this filament compelling.

Key Features

• Ultra High-Speed Printing: Formulated for higher fluidity and quicker melting, it supports speeds up to 600mm/s when used with a capable printer for much faster print turnaround.
• Higher Strength and Toughness: The PLA plus formulation produces prints with improved mechanical strength and resistance to cracking under stress, making models more durable.
• Accuracy & Consistency: The filament maintains a precise diameter of 1.75mm with a tight tolerance of +/- 0.02 mm to reduce extrusion variance and improve dimensional reliability.
• Neatly Wound & No Clogging: Spools are wound without cross-tangling so extrusion remains smooth and nozzle blockages are less likely during extended prints.
• Wide Compatibility: Designed to work with most FDM printers, it is suitable for both high-speed and standard machines like Neptune, Kobra, K1, Ender and similar models.

Who It's For

The filament is best for hobbyists, rapid prototypers and small workshop users who own a higher-speed FDM printer or plan to push speeds above standard PLA settings. Those printing functional parts that see light mechanical stress will appreciate the added toughness and dimensional control.

Users who should look elsewhere include people who need specialty materials such as flexible, high-temperature or carbon-fiber reinforced filaments, and those who prioritize ultrafine surface finish over speed, since PLA+ trades a little polish for strength and faster throughput.

Pros & Cons

Pros

• Prints well at high speeds with smooth extrusion and minimal stringing reported by many users.
• Good value for a 4-pack 1kg supply when comparing toughness and reliability to standard PLA.
• Tight diameter tolerance (+/- 0.02 mm) improves print consistency across long jobs.
• Spools arrive neatly wound, reducing the risk of feed issues during printing.

Cons

• Durability reports are mixed in user feedback, so heavily stressed end-use parts should be tested before critical use.

Our Verdict

The DEEPLEE Rapid PLA Plus is a strong option for makers who want to accelerate print throughput while keeping parts tougher than standard PLA. It offers excellent dimensional control and smooth feeding on a neatly wound spool, making it good value for frequent users. Try it for functional prototypes and fast iterations, but validate strength for heavily loaded end parts before deployment.

Frequently Asked Questions

Can this filament print safely at very high speeds?
Yes, it is formulated for higher fluidity and can be used at speeds up to 600mm/s on suitably capable printers, though tuning is recommended for optimal results.

Is this filament compatible with common FDM printers?
Yes, it fits most FDM machines and is reported to work well with models like Neptune, Ender, Kobra and K1 series printers.

Will prints made from this filament be durable?
PLA plus improves toughness and resistance to cracking compared with standard PLA, but some users report mixed durability so testing is advised for critical parts.
