 |
| The name "Craftwerk" is a play on the German word for power plant. Popfab is a crafting plant. | Nadya designed the logo, which we had vinyl cut (and also put on t-shirts) at a shop in Berlin. |
 |
 |
| The XY motion stage is based on the CoreXY platform. The Z axis arm folds around it. | The Z axis has a wide foot that gets pinned by a thumbscrew to the base when unfolded. |
 |
 |
| A piece of acrylic with a bottom-etched grid serves as the work surface for most activities. | The leadscrew-driven Z axis is constructed of waterjet-cut ribs, and uses a similar bearing system to the X and Y axes. |
 |
 |
| This kinematic coupling provides a rigid, repeatable, and quick-change interface for toolheads. | Preload is applied to the kinematic coupling using a single thumb-screw. |
 |
 |
| 3D printing toolhead | Just getting started on a 3D print. |
 |
 |
| A high-speed machining spindle | PCB milling is a well suited application for the light duty but high speed spindle. |
 |
 |
| Drag knives have a passively rotating blade that can cut vinyl stickers, paper, and other thin materials. | We water-jet cut a miniature cutting mat. Turns out self-healing mats only heal to a point! |
 |
 |
| To support high-speed printing, we used an off-the-shelf control board from Printrbot. | This set of headers provides connections for the various actuators and sensors needed to support multiple processes. |
 |
 |
| Nadya and me and Popfab | We put together a kit with toolheads and supplies, all stored inside a small duffel bag. |
 |
 |
| Outdoor fabricating on a beautiful day outside MIT's Kresge auditorium | The PCB for this small wireless temperature probe was made using Popfab. |
 |
 |
| Popfab was born in the basement lab of the CBA. Here Nadya epoxies the bearings in place. | Still unfinished, Popfab made its way to Berlin via Saudi Arabia. The Saudis were none-too-keen on letting Popfab fly coach, so I paid extra to have it wrapped and sent below. |
 |
 |
| The sunny Airbnb where I stayed in Berlin during the BMW-Guggenheim project. | It was on a visit to Ultimaker that, with their kind help, I modified the Marlin firmware to support CoreXY and successfully control Popfab. |
 |
 |
| It's alive! Popfab's first creation is a drawing of a PCB at Ultimaker HQ. | Erik, Florian, and I at Erik's house, where the machine made its first 3D print |
 |
 |
| Hard at work at the BMW-Guggenheim exhibit in Berlin. | Working with students from MIT's IIH to build an additional ten devices on-site in Berlin |
 |
 |
| XY stages awaiting further assembly | 3D printing at an outdoor restaurant in Berlin |
 |
 |
| One of our guerrilla urban interventions: a lost-and-found at a park in Berlin | The same lost-and-found, but revisited three years later |
