ABE 3D Printer Enclosure

Adaptive Build Environment for 3D Printers

Engineering grade materials require environmental control systems to print reliably. Materials with high glass transition temperatures such ABS and polycarbonate also tend to have very high shrinkage rates, leading to part deformation when printed without environmental control systems. These deformations can take the form of warping the entire print if the shrinkage forces overcome the adherence to the bed. If bed adherence is maintained but shrinkage forces are significant, parts can also suffer from interlayer delamination. For this reason, we decided to develop an modular 3D printer enclosure that can fit our needs for accurate processing of advanced 3D printing materials.

Advanced 3D Printer Enclosure with Adaptive Temperature Control

SD3D’s solution to part warping and delamination is an Adaptive Build Environment (ABE). ABE includes a set of modular panels with variable insulation properties which allows it to adapt to both internal and external influences to the build environment simultaneously. Each ABE panel is capable of absorbing up to 80W of transient thermal energy. Multiple panel sets can be configured to reduce temperature gradients across the build chamber to within 2C.

Improve 3D Printer Throughput and Efficiency

ABE provides a much more efficient solution to high temperature 3D printer enclosure design than the conventional method of differential resistive heating elements. ABE simply contains and redirects the latent thermal energy output from the heated build plate (HPB), hotends and stepper motors while providing a completely sealed build environment from the outside world. This allows for elevated internal ambient temperatures of up to 80C while using less than 160W of dedicated power. Printing engineering grade materials just got cheaper and easier.
