Ultra-Flat Aluminum Bed by Lightweight Labware

Ultra-flat cast aluminum printer bed by Lightweight Labware, machined for Voron-family and Ants-style 3D printer builds that need a rigid, flat bed plate in 120, 160, 180, 250, 300, or 350mm sizes.

Why this bed

• Cast aluminum plate: a flatter, more heat-stable foundation than thin rolled aluminum sheet.
• Ultra-flat bed surface: intended for consistent first-layer geometry when paired with the right heater, magnet, and spring-steel print surface.
• Wide size coverage: small 120/160/180 options for compact builds, plus 250/300/350 options for larger Voron-class machines.

Specifications

• Material: cast aluminum
• Thickness: 6mm on 120/160/180 options; 8mm on 250/300/350 options
• Size options: 120mm, 160mm, 180mm, 250mm, 300mm, and 350mm nominal bed sizes
• Designer/vendor: Lightweight Labware

Fitment and pairing

• Use for Voron-family, Trident/V2-style, and Ants-style builds when your BOM calls for a matching aluminum bed size and mounting pattern.
• Pair it with a matching Universal Silicone Heating Pad and a removable spring-steel surface such as the Double-Sided Textured/Smooth PEI Spring Steel Sheet.
• For a black anodized version, compare the Black Anodized Ultra-Flat Aluminum Bed; for small Ants-focused builds, also check the Ultra-Flat Black Aluminum Beds for Ants.

Check before ordering

• This is the aluminum bed only: heater, magnetic sheet, spring-steel flex plate, PEI surface, and mounting hardware are separate unless a selected bundle explicitly says otherwise.
• Verify your printer BOM for bed size, heater size, and mounting pattern before ordering.
• Existing vendor note: universal to Voron and Ants printers, excluding V0 variants; do not treat this as a universal Voron V0 drop-in.
