PCB printers are able to make PCBs without engraving. they do this by spraying a special type of ink called conductive ink on a flat, hard surface. Printers that can easily print electronic circuits rather than circuit boards are also under development.

Nano Dimension DragonFly 2020PCB Printer
The Nano Dimension DragonFly 2020 PCB printer is touted as the world's first 3-D PCB printer and the first desktop printer to meet IPC guidelines. It can produce PCBs from scratch with a minimum feature size of 80 μm and a maximum of 1.5 mm. the minimum layer thickness is 30 μm or 0.03 mm. the positioning accuracy is 25 μm along any axis. the maximum build size is 200 x 200 x 3 mm. it can produce multilayer PCBs with a total thickness of up to 3 mm. the printer supports many different conductive and dielectric inks.
Voltera V-OnePCB Printer
The Voltera V-One is a printed circuit board printer that is very easy to use and perfect for electronics R&D departments, schools, or researchers. This tool makes it as easy to print circuit boards as it is to print parts.
Users build boards faster, using the Voltera V-One printer to prototype project boards on the desktop. The process is as simple as inputting a gerber file into the Voltera software, pressing print, and the V-One will print out a lifelike circuit, then use the spray paste (solder) and reflow features to solder the electronics to the board.
The Voltera V-One can be used to

Othermill Pro PCB Printer
Othermill Pro is a portable, precise milling machine that allows you to use digital designs to create 2D and 3D objects from durable materials such as wood, metal and plastic.
Othermill Pro is essentially for the production of fast double-sided printed circuit boards with trace widths down to 150 μm. positioning accuracy is approximately 75 μm. workpiece sizes up to 140 x 114 mm are possible. One limitation is that harder materials such as glass and FR-4 cannot be used. the Othermill Pro can be used with a wide range of operating systems and PCB software. It is currently only available in the US.
Voxel8 PCB Printer
The Voxel8 desktop 3D printer was developed based on basic patents related to the University of Illinois and Harvard University and features two different print heads, one based on common FFF/FDM technology using fused wire and the other using conductive silver ink.Functional materials are at the heart of the Voxel8 technology, and according to the company, their silver ink is 20,000 times more conductive than the most conductive thermoplastic wire currently available, and 5,000 times more conductive than carbon-based inks such as Bare Conductive material!
Voxel8's specially formulated inks are deposited through a dedicated 250 micron diameter nozzle. Once printed, it dries quickly at room temperature and requires no post-processing. These properties make it possible to print on traditional thermoplastic materials. 3D electronics printing requires the ability to insert multiple components into the printing process. The Voxel8 desktop 3D printer is equipped with a highly repeatable magnetic print bed that enables you to temporarily remove the printed object during the printing process, insert components, such as LEDs or sensors, and then put them back in to continue the printing process.
This technology has a wide range of potential uses for printed circuits, 3D polymer scaffolds for tissue engineering and advanced materials for energy harvesting storage, among others.
Prometheus PCB milling machine
Prometheus: This is not only a 3D printer.The desktop manufacturing space has been dominated by 3D printers for years, but other types of machines (mills, laser cutters, robotic arms, etc.) are bringing prices to amateurs and small businesses.
Zippy Robotics founder Rocco Tuccio plans to bring custom printed circuit board (PCB) fabrication to engineers and electronics enthusiasts for about $2,500.The Prometheus is a desktop machine that can create real circuit boards in minutes. Tuccio hopes to provide rapid PCB prototyping capabilities to as many people as possible.
What makes Prometheus PCB milling machine different?
1. The extremely small runout error allows you to precisely cut traces down to 7 mils (7 thousand inches), which means you can design with virtually any surface mount component.
2. High spindle speeds allow you to mill 3" x 5" boards in minutes (not hours)!
3. Included software gives you control over the entire tool chain, including the easy-to-use Circuit Factory design software and public API.
4. Prices are a few thousand less than similar precision machines.
1.What is a PCB in a printer?
While design of aprinted circuit board(PCB) can be done internally, manufacturing is generally outsourced. This dependence often results in uncontrollable, and unexpected delays. ... It is here that desktopPCB printersare aiming to come to the rescue.
2.How much does it cost to print a PCB?
In general, thecostto produce aPCBwillcostbetween $10 and $50 per board.
3.How does a PCB printer work?
A specialprintercalled a plottedprinteris used toprintthe design of thePCB. It produces a film that shows the details and layers of the board. When printed, there will be two ink colors used on the inside layer of the board: Clear Ink to show the non-conductive areas.
4.Why are PCB green?
It is due to the solder mask, which protects the copper circuits printed on the fibre glass core to prevent short circuits, soldering errors, etc. ... The colour of the solder mask gives the board its appearance.
5.How much does custom PCB cost?
At BatchPCB,atwo-layer boardcosts$2.50 per square inch (about $0.40 per square centimeter), whileafour-layer boardcosts$8 for the same area (about $1.24/cm2). The first step in creatinga custom PCBis laying out the schematic view.
6.How do I print directly from PCB?
A laserprinteris used toprintan image of thePCBon special “transfer paper” which is then placed on the bare copperclad board and either ironed or run through a modified laminator to transfer the image to the copper.
7.What does PCB stand for?
Printed circuit board. Aprinted circuit board, or PC board, orPCB, is a non-conductive material with conductive lines printed or etched. Electronic components are mounted on the board and the traces connect the components together to form a working circuit or assembly.
8.What is PCB made of?
Copper circuitry. Printed circuit boards(PCBs) are usually a flat laminated compositemade fromnon-conductive substrate materials with layers of copper circuitry buried internally or on the external surfaces. They can be as simple as one or two layers of copper, or in high density applications they can have fifty layers or more.
9.Which type of PCB is more economical type?
Aluminum-BackedPCBs. Aluminum is inexpensive, making almost 8.23% of planet's weight, and leads tomost economicalmanufacturing process.PCBsmade up of aluminum are easily recyclable and non-toxic in nature, making them as ideal source for energy conservation.
10.How do you choose a PCB material?
Electrical functionality is based onPCBfunction, which makes it a good criterion for design-based circuit boardmaterial selection. According to function,PCBsmay be classified as the following board types: High Frequency (High Speed) – These boards can accommodate frequencies in the 500MHz – 2GHz range.
