Introduction
Choosing the right filament can make or break your 3D printing experience. If you’ve been using standard PLA for a while, you might have noticed that your prints sometimes lack flexibility or strength. This raises a common question among makers — when should you stick to basic PLA vs PLA+? Both materials have earned their place in the world of 3D printing, but they serve slightly different needs. In this article, we’ll explore their unique qualities, advantages, and tradeoffs to help you decide whether to stay with PLA or upgrade to PLA Plus for better results.
Understanding the Basics: What is Standard PLA?
Composition and Manufacturing of PLA
PLA, or Polylactic Acid, is a biodegradable thermoplastic made from renewable resources such as cornstarch or sugarcane. It’s one of the most eco-friendly and widely used filaments in 3D printing, popular among beginners and professionals alike.
Typical Performance Characteristics
Standard PLA is known for its ease of printing. It requires relatively low extrusion temperatures (around 190–220°C) and does not demand a heated bed in most cases. Prints come out smooth, and the material produces minimal odor.
Advantages of Using Basic PLA
When comparing PLA vs PLA+, standard PLA shines for its simplicity and reliability. It’s perfect for prototypes, decorative models, and low-stress parts. Its popularity also ensures compatibility with nearly every desktop 3D printer.
Common Limitations of Basic PLA
However, PLA’s biggest weakness lies in its brittleness. It can crack under stress and deform at temperatures above 60°C. If your projects demand more durability or flexibility, that’s where PLA Plus might come into play.
What is PLA+ and How Does It Differ?
Definition and Modifications That Distinguish PLA+
PLA Plus, often referred to as PLA+, is a modified version of standard PLA. Manufacturers enhance it with additives like impact modifiers or other polymers to improve its strength and flexibility.
How These Modifications Affect Print Behaviour
These chemical tweaks make a big difference in performance. In the PLA+ vs PLA comparison, PLA+ exhibits better layer adhesion, less warping, and smoother surface finishes. It’s also more resistant to breaking under pressure.
Advantages of PLA+
The benefits of PLA Plus are easy to spot: tougher prints, more elasticity, and improved temperature resistance. It’s an excellent choice for mechanical parts, enclosures, or models that might face light wear and tear.
Potential Tradeoffs or Considerations
The only downside? PLA+ may require fine-tuning your printer’s temperature settings and costs slightly more per spool. Still, the overall performance boost often makes the upgrade worthwhile.
Side-by-Side Comparison: PLA vs PLA+
Mechanical Properties
When comparing PLA vs PLA+, strength is the biggest difference. PLA+ offers noticeably higher impact resistance, reducing the likelihood of brittle failures.
Print Quality and Finish
PLA+ prints generally appear smoother, with less visible layer lines. However, PLA can still produce beautiful results for aesthetic models when properly tuned.
Usability
PLA remains the easier option for complete beginners. PLA+ might demand minor adjustments, such as increasing the print temperature by 5–10°C, to achieve ideal results.
Cost-Effectiveness
Basic PLA is slightly cheaper, but PLA+ offers better part longevity and performance. For users printing functional objects, PLA Plus delivers more value in the long run.
Suitable Applications
PLA is perfect for low-stress, artistic projects. PLA+ excels in parts that require durability—like tools, casings, or even RC model components.
When Should You Stick with Basic PLA?
Ideal Use Cases
Stick with basic PLA when you prioritize speed, affordability, and ease of use. It’s ideal for visual models, prototypes, or student projects where mechanical strength isn’t critical.
Printer Types and User Experience
Beginners will find PLA more forgiving. It performs well on entry-level printers and doesn’t require advanced calibration.
Budget or Workflow Reasons
If you print frequently and cost per gram matters, PLA remains the most economical option. For makers producing large quantities of decorative items, PLA’s low price and consistent results are unbeatable.
When It’s Time to Upgrade to PLA+
Signs Your Prints Highlight Limitations of Basic PLA
If your prints keep snapping under minimal pressure or deform when exposed to mild heat, you’re ready to move up to PLA Plus.
Projects or Demands That Warrant PLA+
For mechanical prototypes, wearable gadgets, or parts that need to endure friction, PLA+ vs PLA testing will clearly favor PLA+. It’s more reliable for professional-grade results and outdoor applications.
Printer Upgrades or Settings Adjustments
Upgrading doesn’t mean buying a new printer. You just need to tweak your temperature settings slightly (typically 205–230°C). Some users also reduce cooling to allow better layer bonding.
Practical Tips for Making the Switch (or Staying with PLA)
Testing PLA+ on Your Setup
Start with small test models when experimenting with PLA Plus. Note the extrusion smoothness and layer consistency before moving to large projects.
Adjusting Slicer Settings
Increase the nozzle temperature, slow down the printing speed slightly, and ensure your cooling fan isn’t too aggressive. These adjustments help PLA+ perform optimally.
Best Practices for Bed Adhesion and Post-Processing
PLA+ adheres well to glass or PEI beds but benefits from glue sticks or adhesive sprays. Post-processing—like sanding or painting—also tends to be easier due to PLA+’s smoother surface.
Cost vs Benefit Evaluation
If you print small-scale art models, basic PLA might suffice. But for functional parts and long-term durability, PLA vs PLA+ comparisons consistently favor the upgraded material.
Summary and Final Recommendations
At the end of the day, both PLA and PLA+ have strong roles in the 3D printing ecosystem. Basic PLA remains unbeatable for simplicity, affordability, and eco-friendliness. However, when your prints demand higher durability, flexibility, or heat resistance, PLA Plus is the smart upgrade. If you’re new to 3D printing, start with PLA. Once you’ve mastered it and crave stronger, longer-lasting results, make the move to PLA+. The learning curve is minimal, but the improvement in print quality is significant — making the PLA+ vs PLA debate an easy one to settle for those ready to take their printing to the next level.
