What Type of Printer Do You Need to Print a PCB?

Printed circuit boards (PCBs) are the heart of countless electronic devices, from smartphones to robots. Traditionally, creating PCBs involves a complex and expensive industrial process. However, advancements in 3D printing technology have opened the door for a more accessible method – DIY PCB printing.

This article explores the different types of printers suitable for PCB creation, key features to consider when choosing one, and compares various PCB printing methods.

Types of Printers for PCB Making

There are three main printer types commonly used for DIY PCB printing:

Inkjet Printers

Modified inkjet printers can be used for PCB creation. They deposit conductive ink onto a substrate, forming the circuit traces. However, this method often requires additional steps for etching and offers limited resolution.

Laser Printers

Modified laser printers offer higher resolution compared to inkjet printers. They use toner powder containing conductive particles that are then fused onto the substrate with heat. Similar to inkjet printers, laser-based methods often require etching.

UV Printers

UV printers utilize a photosensitive resin that hardens upon exposure to ultraviolet light. This allows for the precise printing of conductive traces directly onto the substrate. UV printers offer the highest resolution and require minimal post-processing.

Features to Consider When Choosing a Printer

When selecting a printer for PCB creation, consider the following factors:

Resolution

Resolution refers to the smallest detail the printer can produce. Higher resolution results in finer circuit traces, leading to more complex and reliable PCBs.

Print Bed Size

The print bed size determines the maximum dimensions of the PCB you can create. Choose a printer with a bed size that accommodates your typical project needs.

Connectivity Options

Printers can connect to computers via USB, Wi-Fi, or ethernet. Consider your preferred method of sending print jobs.

Software Compatibility

Ensure the printer is compatible with software designed for PCB layout and printing.

Top Brands for PCB Printing

Several brands offer printers suitable for DIY PCB creation:

ELEGOO

ELEGOO offers a range of 3D printers, some of which can under go a modification for PCB printing with additional components.

ANYCUBIC

ANYCUBIC printers are known for their user-friendly interface and affordability, making them a good entry point for beginners.

Creality

Creality provides a variety of 3D printer models, with some offering large print bed sizes suitable for larger PCB projects.

Comparison of Different PCB Printing Methods

Beyond DIY printing, there are alternative methods for creating PCBs:

Professional PCB Manufacturer

Professional PCB manufacturers offer the highest quality and fastest turnaround time. However, they typically require minimum order quantities and have higher costs.

PCB Milling Machine

PCB milling machines use computer-controlled tools to remove material from a copper sheet, creating the circuit traces. This offers great precision but requires specialized equipment and expertise.

DIY PCB Printing

DIY PCB printing with modified 3D printers offers affordability and flexibility for hobbyists and makers. However, it requires more user input and may have limitations in resolution and complexity.

Cost Comparison

DIY PCB printing is the most cost-effective option, followed by professional PCB manufacturers with minimum order quantities.  PCB milling machines require a significant upfront investment.

Conclusion

The choice of PCB printing method depends on your project requirements, budget, and technical expertise.  DIY PCB printing with modified 3D printers allows for affordable prototyping and small-scale projects.  For professional applications requiring high quality and volume, professional PCB manufacturers remain the preferred choice.
