Michael Lundwall launched a campaign on kickstarter about a new 3D Printer——The RigidBot It is an easy to use consumer 3D printer engineered for the everyday user. You can buy it fully assembled and ready to use, or in kit form and have fun putting it together. The RigidBot 3D design is fully expandable in the X, Y and Z directions. Using the injection molded plastic joints, you can adjust the size by swaping out the metal bars with longer or shorter ones .
