Green marks the generally easier or more forgiving option in that row, based on tier, enclosure needs, and moisture sensitivity. It is not always the better choice for a specific job, so weigh it against what your project actually needs.
Strengths Comparison
PLA Strengths
- Easiest to print, cheap, widely available, fast, good bridges/overhangs, easy support removal
- Stiff non-composite thermoplastic, good tensile strength
Silk PLA Strengths
- Very shiny for show pieces
- Supports can be easier to remove
Considerations
PLA Caveats
- Creeps under sustained load
- Poor heat resistance, UV degradation, can shatter on drops
- Not great for sanding/gluing/painting/touch-ups
Silk PLA Caveats
- Weaker than PLA
- Can puff/popcorn and jam (especially with hot-air intake or multi-material single-nozzle)
- Can 'trash' AMS/MMU
Frequently Asked Questions
What is the difference between PLA and Silk PLA?
PLA prints at 190-220°C nozzle / 50-60°C bed (No enclosure, moderate moisture sensitivity). Silk PLA prints at 190-220°C nozzle / 50-60°C bed (No enclosure, moderate moisture sensitivity).
Is PLA or Silk PLA stronger?
Our dataset does not include comparable tensile strength values for both. Qualitatively, PLA is suited to easiest to print, while Silk PLA is suited to very shiny for show pieces.
Which prints at a higher temperature, PLA or Silk PLA?
Both print at similar nozzle temperatures (190-220°C vs 190-220°C).
Is PLA or Silk PLA better for beginners?
Both are similarly approachable: PLA (no enclosure, moderate moisture) and Silk PLA (no enclosure, moderate moisture).
Should I use PLA or Silk PLA for easiest to print?
For easiest to print, PLA is usually the better fit (Easiest to print). Choose Silk PLA instead when very shiny for show pieces.
