2. What becomes printable

These are the traditional plastic filaments used in 3D printing, spanning from the common ones used by hobbyists to engineering materials used in industrial settings, including also niche polymers rarely seen.
Plastic filaments can be commonly found with a lot of different options, them being different blends of the original polymer or different non meltable fills added to give different properties to the final material.

• $\color{#616161}{\textbf{25°C - Ambient}}$

- What dies:

• Everything will be ok

- What to use:

• Anything is fine

• $\color{#600100}{\textbf{45°C - Enclosed box}}$

- What dies:

• Having the electronics outside of the chamber is preferred
• PLA parts will die, PETG parts will slowly deform

- What to use:

• Anything is still fine

• $\color{#970000}{\textbf{60°C - Properly sealed printer chamber}}$

- What dies:

• Normal greases

- What to use:

• GPL225 grease or equivalent

• $\color{#D50100}{\textbf{75°C - Limit of a standard machine}}$

- What dies:

• PVC wires will degrade
• Class B (130°) steppers could go out of spec
• Parts printed with ABS blends will start to creep
• Fans will have reduced lifespans
• Acrylic Panels will warp

- What to use:

• Silicone or PTFE/FEP wires
• Class H (180°) steppers
• Unblended ABS printed parts or better
• Good quality fans
• PC Panels or better
• GPL226 grease or equivalent

• $\color{#FF7800}{\textbf{120°C - Standard printer design with HT rated components}}$

- What dies:

• Plastic endcaps on the linear rails can start to harden
• PC panels will start to warp
• Printed parts will fail if not printed with HT polymers
• Nearly every fan will die quickly

- What to use:

• All metal rails are preferred
• Metal panels (Aluminium or Steel depending on the frame material)
• Metal parts (lasercut, SLM, or milled) or parts printed with HT polymers (PC-CF/GF, PSU, PPSU, PEI-CF/GF, PPS-CF, PEKK-CF/GF)
• Watercooling is preferred, but Delta fans have been reported to survive ok, just with shorter lifespans

• $\color{#FFB700}{\textbf{150°C - Standard printer design with HT rated components (high maintenance)}}$

- What dies:

todo dead

- What to use:

todo use

• $\color{#FFFF00}{\textbf{250°C - Completely custom machine}}$

- What dies:

todo dead

- What to use:

todo use
