FDM 3D printer filament designed to deliver tougher, low-shrinkage prints with tight diameter control. Peace of mind for makers comes from neat spools, bubble-free flow and broad compatibility. How well does the SUNLU PLA+ 3D Printer Filament perform across long print runs and varied machines?
⚡ At a Glance
- • Dimensional Accuracy: Diameter tolerance of +/- 0.02 mm with excellent roundness and minimal warping
- • Best for: Hobbyists and small workshops using FDM 3D printers and 3D pens
- • Not ideal for: Non-FDM workflows such as SLA/DLP printers or projects requiring elastomeric filaments
High-precision 1.75 mm PLA+ filament combines tight tolerances with a formulation that minimises bubbles and clogs. Neatly wound spools and vacuum packing support reliable feeding and storage.
Consistent Dimensions – With +/- 0.02mm Diameter Tolerance
Manufactured to a diameter tolerance of +/- 0.02 mm and designed for perfect roundness to reduce feed variation during extrusion. Tight tolerances reduce layer shifting and uneven filament feed.
More accurate part dimensions and finer surface detail, especially on small or intricate prints. Reduced warping leads to higher first-time success rates.
Smooth Printing – With Clog-Free, Bubble-Free Formulation
Filament produced without impurities and bubbles to improve melt flow and avoid nozzle blockages. The formulation aims for consistent extrusion behaviour across long prints.
Fewer interrupted prints and less maintenance during runs, making long or multi-hour prints more reliable. Cleaner extrusion also helps achieve glossier surfaces where required.
Easy Handling and Storage – Thanks to Neatly Wound Spools and Vacuum Pack
Spools are wound with a technology that prevents tangles, twisting and filament disconnection during feeding. Vacuum sealing keeps filament dry and prevents contamination from the environment.
Quicker spool changes and lower risk of printing plugs from poor winding. Longer shelf life for spare spools and better first-layer consistency after storage.
✨ The 4 Key Reasons for SUNLU PLA+ 3D Printer Filament

❓ Frequently Asked Questions
Q: Will this filament work with my FDM printer?
A: Compatibility covers 99% of FDM 3D printers and is also suitable for 3D pens, making the filament widely usable across common FDM setups.
Q: What does +/- 0.02 mm diameter tolerance mean for prints?
A: The +/- 0.02 mm tolerance indicates very tight control of filament diameter and roundness, which reduces extrusion variation and helps produce more accurate, consistent prints.
Q: Is clogging likely with this filament?
A: Manufacturing aims for a clog-free, bubble-free formulation and neat spool winding, both of which reduce the risk of nozzle blockages and printing plugs.
🏆 Our Verdict
The filament suits hobbyists and small workshops that prioritise reliable, dimensionally accurate FDM printing. Tight diameter tolerance, a clog-free formulation and vacuum-packed spools form the key selling points. Expect better long-term value through fewer failed prints and more consistent results across multiple spools.
