How PCB Printing Machine Offers One Stop Prototyping Solution In the PCB Industry

The fabrication of a printed circuit board involves several procedures, steps, and the use of several machines. These machines need to be reliable and efficient as they would be performing a great task in PCB manufacturing. The PCB printing machine is an example of machines used in PCB fabrication.

The electronics manufacturing industry has continued to evolve over time. PCB manufacturers can now fabricate PCBs with various engraving techniques.  There has been a huge rise in the demand for electronics prototyping since well-established organizations and startups need to meet the requirements of innovation.

What is a PCB Printing Machine?

A PCB printing machine uses conductive and dielectric inks to produce PCB from scratch. A few of these machines can integrate solder paste. Therefore, a PCB printing machine is a great choice as a one stop prototyping solution. Ass 3D printers become more popular, there are limitless possibilities for home production and rapid prototyping.

The utilization of a 3D program helps to quickly develop any model. After this, you can print the design with ease. A PCB printer can develop and design a prototype board from a workbench. This machine produces an FR4 board by simply putting in files in Gerber format.

This is how the magic works. The PCB printing machine uses conductive inks. The insulating ink and the races develop as a mask between various layers. Also, PCB printing machine allows you to efficiently test your ideas.  PCB printers can make PCBs without the need to engrave. These machines use a special ink known as conductive ink. They spray the ink on a flat, hard surface.

Top Desktop PCB Printers

Desktop printers can print various printed circuit boards and place electronic components with various soldering options. It is crucial to consider a number of factors when choosing a PCB printing machine. You will need to consider features like number of layers, communication, package size, and more.

Voxel8 PCB printer

This is one the best desktop PCB printers. Voxel8 3D printer was specially designed based on basic patents associated with the Harvard University and the University of Illinois. This machine comes with two different print heads. One of these print heads uses fuse wire while the other utilizes conductive silver ink.

This machine deposits its specially formulated inks via a dedicated 250 micron diameter nozzle.  The ink dries quickly and requires no post-processing once it is printed. Therefore, this makes it possible to use Voxel8 on traditional thermoplastic materials. The Voxel8 3D printer features a highly repeatable magnetic print bed that allows you to get rid of the printed object.

Nano dimension dragonfly 2020 PCB printer

This PCB printer is the first 3D Printer in the world. Also, it is the first desktop printer to meet the guidelines set by IPC. This printer can generate a printed circuit board from the scratch with a feature size that ranges from 80 μm and 1.5 mm. Also, the minimum layer thickness is 0.03 mm and the maximum build size is 200 x 200 x 3 mm.

This PCB printer can fabricate multilayer circuit boards with a thickness of about 3mm. Also, Nano dimension dragonfly supports various dielectric and conductive ink.

Squink by BotFactory

This machine can print multilayer boards on various rigid and flexible substrates. Also, single-layer PCBs can be 15.2 x 15.2 cm. However, multilayer PCBs are only restricted to 8.4cm x 15.2 cm. The minimum feature size of this machine can be 0.254mm.

Squink features three heads-one for printing.  Two heads-one are ideal for applying solder paste. The third is for pick and place. Also, it can assemble 4 parts for each minute.

Factors to Consider when Choosing a PCB Printing Machine

There are several PCB printers available out there. However, these printers don’t offer the same features. Some PCB printers offer more advanced features. Therefore, you need to consider some features when choosing a PCB printer.


Speed is crucial for printing circuit boards. Some PCB printers perform at a slow pace while some are very fast. If you want an easy and quick to use printing machine, ensure you consider speed.  For instance, Promethus PCB machine high spindle speeds.

Number of layers

Multilayer boards improve distribution of power and reduce EMI and crosstalk. When choosing a PCB printing machine, the number of layers you intend to fabricate in a crucial factor to consider. Some PCB printers can fabricate multilayer boards with a thickness of about 3mm.


Cost is crucial when choosing a PCB printer. This factor is the overall determinant of your choice. Also, the price of PCB printer varies. Most times, PCB printers with advanced features cost more. For instance, high accurate PCB printers having a 25 μm minimum feature size can be as high as $100,000.

How do 3D PCB Printers Work?

PCB printers make use of dielectric and conductive ink to produce electronic circuits. Also, these boards are very ideal for a prototype printed circuit board. Before the advent of 3D, manufacturers developed prototype PCBs by using a soldering iron. Another choice was to go for a short production run.

 However, the introduction of 3D printers offered limitless possibilities for home production and quick prototyping. Also, a conventional 3D PCB printer can design any model in a 3D modeling program. You can then print this model in your home. 3D PCB printers integrate inkjet deposition printers, advanced nanochemistry and sophisticated software. These features can meet the demands of rapid prototyping.

Furthermore, 3D printers can minimize the time spent in prototyping even for complex and intricate boards. Therefore, this technology offers engineers and designers the opportunities to test and develop their partial PCBs. With this, you can fabricate and test new prototypes the same day. Also, these printers can save some bucks and even enable you to create and design models.

In the long run, this can improve the overall quality of your final PCB and even result in the production of new electronics. Also, PCB 3D printers offer speed, conductivity, and high resolution. With these printers, you can express your imagination due to quicker turnaround times, regular iterations, and quicker prototype.

Furthermore, you can work around different designs and geometrics. This can result in better products. A 3D PCB printer supports high resolution images.

What is a PCB Laser Printer?

You can now produce PCBs at home using several ways. A process known as photoresist produces the most efficient and lasting results. Also, this process involves covering a circuit board with photosensitive paint and exposing it to UV light through a mask. The exposed paint washes away slowly and the uncovered copper etches.

PCB laser printer can help to import PCB layout. Also, you can introduce the layout in form of a bit-map photo. The laser will recreate the precise image pattern by turning off and on. The process where the laser goes over the board must be very fast. This will enhance your resolution and reduce printing time.

PCB laser printers feature a simple hardware design. These printers have a short rotational axis having a laser close to the end of the arm. There is a linear axis that goes over the PCB. Both axes generate power via high-quality stepper motors. The electronic aspect of this printer is usually designed with Raspberry Pi. The Raspberry Pi functions as the primary processing unit.

One of the major drawbacks of 3D laser printer is the lack of speed. This printer uses around 10 minutes to process 1cm over a circuit board. This often leads to thirty minutes for printing even a small circuit board. The inertia in the arm of this printer is what prevents it from reaching higher speeds.


There are various types and sizes of PCB printers. Also, the cost of these machines varies. Therefore, it is crucial to understand that the features and capabilities of different printers differ. High accurate PCB printers having a 25 μm minimum feature size can be as high as $100,000. However, lower specification models can cost $5,000.

Furthermore, PCB printers should never be an option for standard PCB manufacturing machines. This is because these machines are more advanced and more superior in terms of cost and speed. Therefore, you can get great benefits from them as regards mass volume production.
