AM1800 is Taulman n-vent PETT is Taulman t-glase
I am by no means a mechanical engineer and have only an armchair understanding of these properties.
- Glass Transition: starts to deform
- Melt Temperature: becomes liquid
- PC best, ABS good, PETG not too bad, PLA and Nylon bad
- Elastic Modulus (Young's Modulus or Tensile Modulus): higher = less stretchy
- Tensile Strength: higher = resists stretch more
- Nylon best, PC second best, PETG good and will deform at limit, PLA close and will crack quickly at limit
- Flexural Modulus: higher = less bendy
- Flexural Strength: higher = resists bending more
- Nylon best, ABS and PC good and will deform at limit, PLA alright and will crack quickly at limit, PETG a tad weaker and will deform at limit
- Compressive Strength: resists compression more
- PC, Nylon, PETG best, PLA and ABS not so good
- Elongation: how much a stress curve rises, less means crack, more means deform out of shape
I don't really understand this well, and there are a lot of different results from different source, but anyway, I hope this is a good table of Dynamic Coefficient of Friction vs steel:
| Material | Value |
|---|---|
| PTFE (Teflon) | 0.04 to 0.05 |
| Sintered Bronze | 0.12 |
| Bronze | 0.16 |
| Brass | 0.19 |
| POM | 0.2 |
| PET-P | 0.2 |
| PET-G | 0.22 |
| PET | 0.25 |
| Nylon 6,6 | 0.26 |
| ABS | 0.35 |
| PLA | 0.38 to 0.45 |
| PC | 0.38 to 0.5 |
