SUNLU PLA+ 3D Printer Filament (1.75mm, 1kg, Black) – Upgraded Tough PLA Plus
Product description
What it is and what it’s for
SUNLU PLA+ is a toughened version of standard PLA designed for broader durability in general 3D printing projects. Supplied on a 1kg spool and calibrated for 1.75mm filament diameter, it aims to deliver improved toughness without a dramatic drop in printability, making it a practical choice for everyday, non-technical prints that need a bit more resilience.
On-paper performance and design intent
In terms of specification, the filament is claimed to have a dimensional accuracy of +/- 0.02mm and to come neatly wound, which helps feed stability during prints. The manufacturer highlights a reduced risk of printing failures due to tidy winding and a claim of clog-free, bubble-free extrusion thanks to full mechanical winding and multiple quality inspections (including drying and vacuum sealing).
What stands out about this filament
The standout features are the reinforced toughness claimed (more than 11 times that of regular PLA in theory) and the neat winding that should simplify feeding into a 3D printer. For users who print functional parts or parts that experience some stress, this PLA+ variant is positioned as more robust than standard PLA while retaining ease of use typical of PLA-based materials.
Who it’s for
It’s suitable for hobbyists and makers who want a relatively easy-to-habricate filament with a touch more durability for everyday parts, small mechanical components, or prototypes that may experience handling or light impact. If you value straightforward printing with a familiar PLA workflow but need a bit more resilience, this could be a reasonable match.
When it makes sense to buy
Consider SUNLU PLA+ if you prioritise a simple, familiar PLA printing experience but want stronger, tougher prints without jumping to more advanced materials. It may be advantageous when your projects involve moving parts, small jigs, fixtures, or demonstrators that might benefit from higher impact resistance and a stable print process.
What to check before buying
- Ensure your printer is tuned for PLA-class materials and supports 1.75mm filament.
- Use the recommended printing settings as a starting point: nozzle 195–220°C, bed 50–60°C, print speed 50–300mm/s, then optimise for your print geometry.
- Be aware that actual toughness and print results depend on part geometry, cooling, and environmental factors, the stated performance is a reference, not a guarantee.
How it compares to other approaches
If you need maximum strength or heat resistance, composite or engineering filaments would be more appropriate, though they often trade ease of use for durability. For straightforward, consumer-friendly prints where occasional stress occurs, a PLA+ option like this one offers a middle ground: easier handling than PETG or ABS, with more resilience than standard PLA.
Is it worth it?
Is it worth it? Worth considering if you want a practical upgrade over plain PLA without adopting more challenging polymers. It’s not a premium engineering material, but it aligns with a value-for-money approach for everyday parts that may benefit from extra toughness.
Practical FAQ
- How hard is it to print with PLA+ compared to standard PLA? It follows similar printing profiles, with a general recommendation of 195–220°C nozzle and 50–60°C bed, you may need minor tuning for your printer.
- Will this filament clog my nozzle less than other PLA variants? The manufacturer claims clog-free and bubble-free extrusion due to winding and drying, but real-world results still depend on print settings and maintenance.
- Will it be compatible with all FDM printers? SUNLU states broad compatibility for 99% of FDM printers, as always, confirm your printer’s filament tolerance and drive system compatibility.
