Revolutionary Open-Source Tool Transforms 3D Printing Design
A new open-source software platform is reportedly reshaping how engineers approach 3D printing with multiple materials, according to developers at the University of Colorado Boulder. The tool, called OpenVCAD, represents a significant advancement in 3D computer graphics and design capabilities that could transform manufacturing across numerous industries.

Breaking Through Multi-Material Design Barriers
Sources indicate that traditional computer-aided design (CAD) software has long struggled with multi-material objects because these tools typically represent objects as boundary surfaces only. According to reports, conventional software operates with an implicit assumption that everything inside a boundary surface consists of the same material, making gradient designs overwhelmingly difficult to create.
“There’s certainly a history of multi-material design study and practice that existed well before OpenVCAD,” said Assistant Professor Robert MacCurdy of the University of Colorado Boulder, who leads the Matter Assembly Computation Lab where the project was developed. “But we believe the overhead of writing specific code for specific projects every single time prevents engineers from doing as much design as they could.”
Code-Based Approach Enables Complex Designs
Charles Wade, the PhD student in the Department of Computer Science who created OpenVCAD, developed the software package to use functions and code that map not just shapes but also material distributions within 3D objects. Analysts suggest this approach represents a fundamental shift in how system software handles multi-material design.
“This is the first multi-material, code-based design tool that is widely available,” Wade stated. “It allows for good complexity when printing objects, it’s accessible and it’s intuitive to write and design. Unlike traditional CAD software, where you’re forced to sketch everything out for each change and you cannot represent graded materials, our tool allows users to change one small variable and watch the whole design update in an easy way.”
Broad Applications Across Industries
The report states that OpenVCAD’s capabilities extend across multiple fields and applications:
- Medical Planning: Surgeons can create realistic planning models with gradient mixing properties
- Soft Robotics: Experts can design flexible actuators that bend in specific directions while maintaining stiffness elsewhere
- Advanced Manufacturing: Engineers can simulate complex multimaterial objects and export simulation-ready files
- Impact Engineering: The tool can apply specific mechanical properties to lattice structures for impact-absorption
The development comes amid broader technological discussions in the industry, including ongoing debates about work-life balance approaches among technology leaders and major data center acquisitions involving companies like Nvidia and Blackrock.

Open-Source Accessibility and Future Potential
According to the research team, OpenVCAD is completely open-source and includes a Python implementation, allowing users worldwide to import the repository and begin working with just a single line of code. This accessibility approach contrasts with other technology sectors where, as reports indicate regarding rare earth minerals, access to critical components remains challenging.
The tool’s development also aligns with growing interest in sustainable technology solutions, similar to Europe’s first cross-border hydrogen valley project and contrasts with traditional energy approaches where federal officials have recently rejected massive coal lease bids.
“We’re able to rely on OpenVCAD’s core capabilities to represent multi-material objects in a bunch of different domains,” MacCurdy said. “But there is a lot more coming in certain areas that we are excited about and we’re really hoping this approach to multi-material design takes off.”
The researchers emphasize that the tool’s open-source nature will help build a community of users, similar to how government support packages aim to stimulate broader economic activity. Wade added, “We have a growing base of external researchers from other institutions who are using this tool and we hope to enable that community to do their best work.”
