The HotBox® is made of a sandwich of 3 materials selected to create structure and excellent insulating properties. The result is a lightweight semi-rigid construction, so structural that you can place a few spool holders or even the AMS on top of the unit. The exterior is made of a flame retardant, ballistic Nylon 600D, the center is a structural honeycomb polymer panel selected for its insulation properties, and the interior is a metal lining that reflects and maintains optimal temperatures (between 35-60°C) for the duration of the print. Watch our temp testing video on YouTube.

Our entire HotBox® line comes with an optional vent port where you can mount a fan to either filter or pipe the fumes out a window. An easy-to-make fume extractor, 3D models, parts lists, and instructions can be found on Cults here. A Video Short showing the build is here.

The HotBox® was able to achieve a nearly 20% reduction of noise in comparison to the bare P1P, the P1P with Bambu plastic panels, and even the X1 with its metal enclosure. See the machine noise comparison video here.

Unlike other solutions, the P1P HotBox® allows you to access either side of your Bambu Lab printer easily by just unzipping the side and swinging it open. The front door allows full access to the build plate and interior. And the whole unit is removable in less than 10 seconds should you need to work on your printer.

Other great features:

• A built-in thermometer (two LR44 batteries not included) to easily view the internal temperature.
• The front panel has a large clear window for maximum visibility which is a fully openable door that remains fixed to the side when you need front access. No more glass breakages, no more obstructions!
• The right side panel touts tool pouches and elastic straps to keep your most needed tools at arm's reach.
• The rear has openings for venting, the poop chute, the power chord, and the switch.
• A removable patch should you ever mount a rear panel with an extra CPU fan.
• A line of printable accessories is available on cults. A custom poop bucket for use with the P1P HotBox® and an AMS buffer mount that allows you to use an upgraded buffer with the P1P HotBox®.
