1. Today, PCBs are still manufactured using a traditional subtractive process. In this method, the entire surface of the PCB is typically coated with copper, and areas that are not needed are etched away from the board. It’s akin to sculpting a piece of wood, removing excess material to achieve the desired shape and structure. However, this process generates a significant amount of waste.
2. The 3D printing additive manufacturing approach represents a stark departure from subtractive methods. Instead of removing copper from the FR4 substrate, it involves starting with a thin FR4 substrate and adding copper traces using conductive ink. This results in substantial material savings, with 3D printing additive manufacturing capable of reducing material costs and waste by up to 90%. Additionally, it offers greater flexibility in design and innovation, making it a potential paradigm shift in PCB manufacturing.
3. The benefits of additive manufacturing for PCBs include:
– Reduced material usage, promoting environmental sustainability.
– Higher board density, enabling smaller routing areas.
– Consistent path definition and width, enhancing signal integrity.
– Thinner and more flexible circuits, ideal for wearable applications.
– Improved consistency in electrical and mechanical properties.
– Enhanced quality control for electronics featuring flexible/rigid circuits and varying trace thickness.
4. Additive manufacturing solutions for electronic products encompass both 3D printing and 2D printing. In 3D printing, circuit boards are built layer by layer from scratch using various conductive inks, gels, and substrates formulated at the nanoparticle level. Electronic printers employ inkjet technology, material extrusion technology, and Aerosoljet technology.
5. The evolution of hardware and software progresses hand in hand. Despite being relatively nascent, 3D printing of PCBs faces challenges related to material complexity and extrusion requirements. In 2019, DragonFly Pro 3D Printing introduced the world’s first 3D printed PCB side assembly technology. This precision additive manufacturing system enables the printing and soldering of components on the top, bottom, and sides of the PCB. DragonFly LDM printing technology, launched by NanoDimension on July 24, 2019, builds upon the capabilities of the DragonFly Pro system, incorporating proprietary technology for continuous 24/7 printing. Improvements include an advanced print head software management algorithm and automatic print head cleaning at regular intervals.
6. In contrast, 2D inkjet printing is another form of additive manufacturing utilized in PCB production. These machines utilize print heads to deposit conductive traces on flat, horizontal substrates. It’s crucial to ensure seamless integration between these desktop PCB 3D printers and the design software. Autodesk Fusion 360’s Eagle software stands out as a powerful and practical PCB design solution, featuring a schematic editor, PCB editor, and automatic routing module.
