What is 3D print circuit board？

3D print circuit board is an electronic circuit produced via a 3D printer.Printing conductive track PCB material on a uniform board, with technological advances and the need for more flexible circuits, requires a printing technique that can print not only on uniform surfaces but also on uneven surfaces and even in the product itself.

What material to use for a 3D printed circuit board？

• Wire with a plastic coating
• Diluent (acetone)
• etching treatment
• copper-clad plate
• home iron
• laser printer
• cutlery cleaner
• magazine or booklet

Advantages and disadvantages of a 3D-printed PCB

Advantage

• Cost-effective: 3D print circuit board consumes less material.
• Reduce waste: 3D printed PCB makes circuits more compact and more complex, thus saving materials.
• Fast production: With 3D printers, PCB production time will be calculated in hours, which can speed up the entire process.
• High precision: A 3D printer can even place components, reducing the likelihood of human error during production.
• Freedom of design: A PCB produced using a 3D printer can be in almost any shape or can be printed using flexible materials.
• On-Demand Production: 3D printing allows you to produce circuit boards on demand without inventory and reduces storage costs.

Disadvantages

• Low conductivity: 3d print circuit board is constantly improving, but some conductive printing materials are not as good as conventional materials.
• Limited materials: As a relatively new technology, 3d print circuit board is not widely available for use.
• Circuit board size is limited: a 3D printer can only produce the allowable PCB size of its printing room.
• Lack of choice: few companies currently make PCB 3D printers commercially.

Application of 3D printed circuit boards

• Wearables: 3D printing to make custom circuit boards for wearable devices (such as fitness trackers and smartwatches).
• Medical treatment: For building medical devices, such as prosthetics and hearing AIDS.
• Robots: a unique circuit used to make robots and drones.
• Internet of Things: Make custom circuit boards for Internet of Things devices (such as smart home devices).
• Automotive: Auto sensors and other components and custom circuits.
