• Acrylic (Plexiglas): Good for visibility and moderate thermal performance. Lightweight and clean-looking but poorer insulation, scratches easily, and can crack from heat/stress. Not ideal as the sole material for high-temp enclosures.
• Polycarbonate: Much tougher and more temperature-resistant than acrylic; good if impact resistance is needed. More expensive and may yellow over time.

• Insulating panels (e.g., Laser protective sheet): Excellent thermal control and light weight.

• Flame resistant polycarbonate sheet

For typical hobby PLA printing, skip the enclosure. If you have warping on large prints or a cold/building environment, a simple partially enclosed box or draft shield can help.

When it uses for 3D printer enclosure, polycarbonate is better for strength and heat resistance; acrylic is better for clarity, cost, and scratch resistance but is more brittle.

Heat Resistance: While acrylic sheets can withstand moderate temperatures, they have lower heat resistance compared to materials like polycarbonate. Users should ensure that the enclosure setup and printer operation do not reach temperatures that could cause the acrylic to deform or warp.
Flammability: Acrylic is a flammable material, so it is important to consider fire safety measures when using acrylic sheets in a 3D printer enclosure. Avoid placing heat sources near the acrylic and ensure proper ventilation to minimize fire risks.
