The Purple STEAM is a robotic printed pavilion designed by Portland-based designer Volkan Alkanoglu and located at the forecourt of Durham County Main Library in Durham, North Carolina. The robotically 3D-printed abstract structure is approximately 5.4 meters tall, 9.70 meters long, 4.5 meters wide, and 218 kg.
Alkanoglu worked with Tennessee-based 3D printing specialist Branch Technology for fabrication and YetiWerkurks for engineering. The pavilion was 3D-printed with ABS filament and other sustainable materials. The form was created in Autodesk 3ds Max and optimized via Grasshopper and Rhino.
Parenthetically, If you are curious to dive deeper into Volkan Alkanoglu’s works, you can check out Computational Design: NEXT 3.0.
Inspiration of the Purple STEAM came from Alice Walker’s Pulitzer prize-winning “The Color Purple” and Crockett Johnson’s children’s book “Harold and the Purple Crayon.” The structure’s purple tones appear in different colors at night and during the day, depending on the light.
The 3D-printed work produces spatial ambiguity and aesthetic effects by merging, mixing, and overlaying its hundreds of separate components using unique technology and dynamic shape. The pavilion looks at the contrast between day and night. The ambiance created by the installation in the space creates a reading and meeting point for the visitors.
