Laser cutting is an essential part of many industries, from automotive manufacturing to construction, however, the process is not always easy or efficient: Cutting huge sheets of metal takes time and effort. expertise, and even the most careful users can still produce huge amounts of leftover materials that are wasted The underlying technologies that use lasers to cut edges aren’t really cutting edge: their users often don’t know how much of each material they’ve used, or if a design they have in mind can even be. be made

With that in mind, researchers at MIT’s Computing and Artificial Intelligence Laboratory (CSAIL) have created a new tool called Fabricaide that provides live feedback on how different parts of the design should be placed. on their sheets – and can even analyze exactly how much material is used

“By giving feedback on the feasibility of a design as it is created, Fabricaide allows users to better plan their designs within the context of the available materials,” says Ticha Sethapakdi, PhD student, who led developing the system alongside MIT professor Stefanie Mueller, undergraduate student Adrian Reginald Chua Sy and Carnegie Mellon University doctoral student Daniel Anderson

Fabricaide has a workflow that the team believes dramatically shortens the feedback loop between design and manufacture The tool keeps a record of what the user has done, tracking the quantity of each material It also allows the user to assign multiple materials to different parts of the design to be cut, simplifying the process to avoid headaches for multi-material designs

Another important part of Fabricaide is a custom 2D wrapping algorithm that can organize parts on sheets optimally and efficiently, in real time The team has shown their algorithm to be faster than open source tools existing ones, while producing a comparable quality (The algorithm can also be disabled, if the user already knows how he wants to organize the materials)

“A lot of these materials are very scarce resources, and so a problem that often arises is that a designer does not realize that they are running out of material until they have already cut the design. “, says Sethapakdi” With Fabricaide they could find out sooner in order to proactively determine the best way to allocate materials “

As the user creates their design, the tool optimizes the placement of parts on existing sheets and provides warnings of insufficient material, along with suggestions for material substitutes (e.g. , using 1mm thick yellow acrylic instead of 1mm red acrylic) Fabricaide acts as an interface that integrates with existing design tools and is compatible with 2D and 3D CAD software like AutoCAD , SolidWorks and even Adobe Illustrator

Going forward, the team hopes to incorporate more sophisticated properties of materials, such as strength or flexibility.The team says they could consider using Fabricaide in shared creative spaces to reduce waste A user can see that, for example, 10 people are trying to use a particular material and can then switch to a different material for their design to conserve resources
