3D printer filament engineered for stronger, low-shrinkage prints. The eSUN PLA+ Filament brings enhanced toughness and consistent feeding so makers can finish longer prints with confidence. Are four full 1kg spools and +/-0.03mm tolerance the practical upgrade workshops need?
⚡ At a Glance
- • Print Quality: High dimensional accuracy, low shrinkage and reliable layer bonding
- • Best for: Hobbyists, cosplayers and small workshops printing functional parts
- • Not ideal for: Flexible TPU jobs or high-temperature engineering filament requirements
Enhanced toughness PLA+ reduces brittleness while keeping PLA's ease of printing. Tight diameter tolerance of +/-0.03mm and careful winding support steady feeding for long prints.
More durable parts – Thanks to Enhanced Toughness PLA+
PLA+ formulation increases polymer strength and toughness using starch-derived raw materials, while maintaining PLA-like melting and adhesion characteristics.
Stronger prints are less likely to snap, making them suitable for brackets, cosplay armour and everyday functional components.
Reliable dimensional accuracy – With +/- 0.03mm tolerance
Manufacturing controls hold filament diameter tightly to +/-0.03mm, reducing extrusion variation and ensuring consistent layer widths across a print.
Consistent dimensions reduce fitment issues, cutting down rework and wasted material for multi-part assemblies.
Fewer stoppages on long runs – With precise winding and smooth melt behaviour
Spools are wound for good roundness and tight diameter tolerance, while the material melts predictably for steady flow and minimal stringing.
Smooth feeding and low chance of tangles or nozzle clogging help complete large or high-speed prints without interruption.
✨ The 4 Key Reasons for eSUN PLA+ Filament
- Wide printer compatibility - Works with many FDM printers, reducing setup hassles for users
- Enhanced toughness - Produces stronger parts less likely to crack under stress
- High-speed friendly - Handles faster extrusion without frequent clogs or print failures
- Plant-based PLA+ - Uses renewable starch raw materials, lowering reliance on petroleum feedstocks

❓ Frequently Asked Questions
Q: Is this filament compatible with my Ender 3 or Prusa printer?
A: Yes, compatibility includes printers such as Ender 3 and Prusa, and the filament suits most FDM machines.
Q: Will the filament warp or deform during printing?
A: No, PLA+ is described as having low shrinkage and minimal deformation, helping maintain dimensional accuracy.
Q: Is there a risk of tangles or nozzle clogging with long prints?
A: Spools are wound for good roundness and tight diameter control, and the filament is said to feed smoothly without clogging.
🏆 Our Verdict
Suited to hobbyists, makers and small workshops that need tougher, reliable PLA prints. The combination of enhanced toughness, tight diameter tolerance and careful spool winding reduces failed prints and post-processing. While costs vary by supplier, long-term value arrives through fewer reprints and more consistent, usable parts.
