The Top 4 Desktop PCB Printers

December 13, 2016Muhammad
Deadlines are an unpleasant part of life for an electronic designer. While design of a printed circuit board (PCB) can be done internally, manufacturing is generally outsourced. This dependence often results in uncontrollable, and unexpected delays. Just imagine if you had to wait days or weeks to get an assembled PCB, only to find out that there was one small error. Then, knowing that upon correcting the error, that you’d have to wait days or weeks yet again. It is here that desktop PCB printers are aiming to come to the rescue.

About Desktop PCB Printing

Already, replacement teeth and even body joints can be 3-D printed, so why not PCBs? Desktop PCBs are (to some extent) an application of 3-D printing (also known as additive manufacturing)These printers can print a variety of PCBs, and even place components with a variety of soldering options. Upon uploading a software file, a ready-to-test PCB will be delivered. Keep in mind though that the quality of the boards are more geared towards prototyping.

The Top 4 PCB Printers

When selecting a PCB printer, one should evaluate features such as the minimum line spacing or package size, number of layers, substrate materials, whether it can do pick-and-place of components, speed, communication, and cost. We have briefly evaluated five of the top machines in the market based on these features, so let’s take a look. (Printers are listed in no particular order)

#1 – Nano Dimension DragonFly 2020

 
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 minimum feature sizes of 80 μm and maximum of 1.5 mm. The minimum layer thickness is 30 μm or 0.03 mm. Positioning accuracy is 25μm along any axis. The maximum build size is 200 x 200 x 3 mm. It can produce multiple layered PCBs with a total thickness up to 3 mm. The printer supports many different conducting and dielectric inks.
Price: $50,000 – $100,000

#2 – Voltera V1- PCB Printer

 
The Voltera V1 is an economical machine sufficient for producing prototype PCBs. PCBs of up to 135 mm by 113.5 mm can be printed with traces of minimum width 200 μm. Minimum pin-to-pin pitch is 0.8 mm with the conductive ink, and 0.6 mm with solder paste. It is compatible with multiple CAD packages.
Price: $2,199

#3 – Squink by BotFactory

 
Squink can print multilayer PCBs on different rigid as well as flexible substrates. Single-layer circuits can be made to 15.2 x 15.2 cm, while multi-layers are limited to 8.4cm x 15.2cm. Minimum feature size can be 0.254 mm, but 0.508 is recommended. It has three heads-one for printing, the other for gluing or applying solder paste, and the third for pick and place. It can assemble at 4 parts per minute, with the smallest package size of 15.4 mm. Automatic placing of through-hole components may become available later.
Cost: $3,199

#4 – Othermill Pro

The Othermill Pro is essentially a portable milling machine adapted to produce fast double-sided PCBs with trace widths down to 150μm. Positioning accuracy is about 75 μm. Work piece size can be up to 140 × 114 mm. One limitation is that harder materials like glass and FR-4 cannot be used. The Othermill Pro works with multiple operating systems and PCB software. Currently only available in the U.S.

Cost: Just above $3,199
