RepRapper MPLA Extra Strong PLA Plus Filament 1.75mm - Tough Prints

In this review the RepRapper MPLA Extra Strong PLA Plus is evaluated as a tougher variant of standard PLA aimed at users who need stronger, attractive prints without changing printers or workflow. The bottom line: it is best for hobbyists and small shops that want up to five times the impact resistance of ordinary PLA while retaining easy printing characteristics, and it delivers consistent color and surface finish on many machines, though a few users report stringing and adhesion quirks that are worth noting before large projects.

Key Features

• Up to 5x tougher: The modified PLA formulation increases impact resistance so printed parts stand up better to knocks and drops.
• Works on every 3D printer: The filament is designed for broad compatibility, letting users print strong and accurate parts without hardware changes.
• Laser-controlled diameter: Precise diameter monitoring and automatic winding reduce tangles and filament variance for reliable long prints.
• Made with Ingeo PLA: Using pure NatureWorks Ingeo raw material aims to deliver the familiar printability and surface finish of PLA.
• Professional packaging: Spools are dried and vacuum packed in a resealable bag to preserve filament between uses and lower moisture issues.
• Nozzle cleaning needle included: A small but useful tool is provided to help clear clogs or maintain consistent extrusion.

Who It's For

The RepRapper MPLA suits hobbyists, educators, and small workshop operators who want tougher PLA parts without switching to ABS or specialty polymers; it is a good choice when impact resistance matters but printing simplicity is still a priority. Its vacuum-sealed packaging and diameter control also make it convenient for longer runs and multi-part jobs where consistency matters.

Users who require perfectly predictable adhesion or who are extremely sensitive to stringing may need to test settings first, and those needing flexible or high-temperature engineering plastics should look elsewhere for specialized materials.

Pros & Cons

Pros

• Higher impact resistance preserves part durability compared with standard PLA.
• Reliable winding and laser diameter control reduce tangles and feeding problems on long prints.
• Attractive color and surface finish give professional-looking results for visible parts.
• Convenient packaging and a nozzle cleaning needle help maintain filament condition and printer uptime.

Cons

• Some users report occasional stringing and adhesion variability that may require tuning of print settings.
• Mixed reports on brittleness suggest batch and color differences could affect performance for very demanding parts.

Our Verdict

The RepRapper MPLA Extra Strong PLA Plus is a sensible upgrade for users seeking tougher PLA prints without extra printer complexity; it offers strong impact resistance, good surface appearance, and reliable spool handling that make it good value for hobbyists and small shops. Test for stringing and adhesion on your machine before committing to large batches, but overall it balances durability and printability well.

Frequently Asked Questions

Will this filament work on any 3D printer?
Yes, it is formulated to print on standard 1.75mm FDM printers without hardware changes, though slicer tuning may be needed.

Does vacuum packing prevent moisture issues?
The dried spool and resealable vacuum bag reduce moisture uptake but long-term storage with desiccant is still recommended for best results.

Is it much harder to print than regular PLA?
No, it maintains PLA-like printability while increasing impact resistance, though some users adjust retraction and temperature to manage stringing.
