FusePrint: A DIY 2.5D Printing Technique Embracing Everyday Artifacts

This paper proposes a stereolithography-based 2.5D rapid prototyping technique that allows high-precision fabrication without high-end modeling tools, enabling the mixing of everyday physical artifacts and liquid conductive gels with photo-reactive resin during the printing process, facilitating the creation of 2.5D objects that perfectly fit the existing objects. Based on our polynomial model on 2.5D resin printing, we developed the design interface of FusePrint, which allows users to design the printed shapes using physical objects as references, generates projection patterns, and notifies users when to place the objects in the resin during the printing process. Our workshops suggested that FusePrint is easy to learn and use, provides a greater level of interactivity, and could be useful for a wide range of applications domains including: mechanical fabrication, wearable accessory, toys, interactive systems.

The setup was implemented based on the infrastructure of SLA 3D printing process, consisting of three main stages: design, print, and post-process.The design software contains a web-based sketch interface which allows users to design the 2.5D patterns on mobile tablets, and a plug-in for Microsoft PowerPoint to generate projection patterns based on the design of 2.5D shapes designed by the users. We chose Microsoft PowerPoint due to its large user base and the relative simple and familiar interface for its shape and drawing functionalities for users’ further modification on the patterns. To create 2.5D patterns, users first need to draw the bottom shape of the object in the canvas of the sketch interface

The sketch interface allows user to specify the height to place physical objects during the printing process. By clicking the “Place Objects” button, user draws a new stroke between bottom and top lines, to provide the information about placing physical objects. This information will be processed by the PowerPoint plug-in to generate corresponding slide for notifying the user to put in objects during printing.
