The Bambu Lab P1S dimensions are 389 x 389 x 458 mm (15.3 x 15.3 x 18.0 in), and the printer weighs 12.95 kg (28.6 lb) net, per Bambu Lab’s P1S page. The print area is 256 x 256 x 256 mm (10.08 in).

Add an AMS and you need more room for the unit and its spools. This guide gives the exact numbers in inches and mm, so you can check your desk before you buy.

Bambu Lab P1S Dimensions and Size (Without AMS)

The Bambu P1S size is the same on every side: 389 mm wide and deep. It stands 458 mm tall. That is a full-size enclosed 3D printer, and it needs a solid surface.

The weight matters as much as the footprint. At 12.95 kg net, the P1S is heavy for a desktop printer. The shipping weight is 17.60 kg (38.8 lb) and the box measures 485 x 480 x 530 mm. Check that your shelf can hold the load.

Printer size and print area are different numbers. The 389 mm figure is the outside of the machine. The 256 mm figure is the room for your part.

Bambu Studio also sets the default printable height to 250 mm (9.84 in). The last 6 mm needs a manual change, and Bambu explains the safety steps on its store page.

Bambu Lab P1S Size With AMS (Footprint and Desk Space)

The P1S with AMS needs more room than the printer alone. The combo box measures 485 x 480 x 585 mm. The gross weight, with the AMS included, is 21.60 kg (47.6 lb).

The newer AMS 2 Pro measures 372 x 280 x 226 mm, according to a US retailer listing. Bambu Lab now sells the P1S in an AMS 2 Pro combo, and the combo comes in separate boxes.

Here is simple math for planning. These are estimates, not Bambu numbers.

• Side by side: about 761 mm (30 in) of total width, plus cable room.
• Stacked on top: about 684 mm (26.9 in) of total height. That leaves little overhead clearance, and it blocks easy access to the top.

One AMS holds four spools. It fits spools 50 to 68 mm wide and 197 to 202 mm across. Together, AMS units can feed up to 16 colors. The combo with an AMS Hub links up to four units.

The enclosure has no chamber heater. It holds in heat from the bed.

While the Bambu Lab P1S offers impressive 3D printing capabilities in a compact footprint, planning your workspace efficiently is essential for balancing equipment and available room.

Bambu Lab P1S Print Area and Space Planning Tips

The P1S print area is a 256 mm cube. It handles brackets, organizers, enclosures and most tabletop parts. Large helmets and long panels need to be split.

Brims, supports and purge lines use bed space. Slice the real file before you decide that a part fits.

Multi-color jobs need extra room. The AMS purges filament at each color change, so the purge tower takes space on the plate. Rotating a long part diagonally can also help it fit.

Setup tips for your desk:

• Leave a gap behind the printer for the filament path and cables.
• Keep the front free so the door can open.
• Use a level, stable surface that can take the weight.
• Keep the printer away from drafts.
• Leave air space around the vents.
