Top 6 Best PCB Printers on Your Desk

Professional PCB fabrication traditionally required sending designs to manufacturers and waiting days or weeks to receive finished boards. However, desktop PCB printers now allow conveniently printing circuit boards in-house.

This article reviews the top 6 desktop PCB printers currently available. We will compare key specifications, capabilities, and pros/cons of each model to determine which best suits different applications and budgets. Read on to find the ideal desktop PCB printer to bring your electronics projects to life.

Overview of Desktop PCB Printers

Modern desktop PCB printers leverage various technologies to turn copper-clad plastic or ceramic substrates into functional circuit boards:

  • Mechanical Drilling – For holes and vias
  • Laser Machining – Ablates away copper
  • Milling – Uses end mills to isolate traces
  • Inkjet Printing – Deposits conductive inks
  • Photolithography – Selectively etches copper similarly to industrial processes

By combining these methods, multimodal desktop printers can fabricate detailed single or double-sided boards with fine features comparable to industrial standards. Let’s examine the top models.

Desktop PCB printers grant electronics designers, engineers, and makers the ability to quickly turn their circuits into physical boards without relying on external fabrication.

From budget inkjet models to professional laser/milling systems, today’s desktop printers offer resolutions down to 1 mil and features rivaling small-scale manufacturing capabilities. As the technology continues advancing, expect wider adoption driving faster iteration in circuit design innovation.

Frequently Asked Questions

What materials can desktop PCB printers work with?

Most support common FR-4, polyimide, ceramic, and Rogers substrates. Some models allow printing flex PCBs on polyimide films. Material choice depends on requirements like flexibility, high frequency, thermal conductivity.

How many layers can desktop printers produce?

Entry-level printers generate single layer boards, while advanced models support multilayer with either double-sided printing or layer lamination. However, 4+ layers remain in the domain of full-scale PCB fabrication.

What precision and minimum feature sizes can desktop PCB printers achieve?

Leading desktop printers offer 1 mil features and accuracy rivaling industrial equipment. High-end laser, milling, and inkjet models can produce traces and spaces down to 4-5 mils. Entry-level printers support 10 mil features.

What desktop PCB printers are best for small prototypes?

For hobbyist and educational use, low-cost inkjet printers like the Voltera V-One provide an accessible starter option. For more advanced engineering prototypes, the LPKF ProtoMat E34 or BotFactory SV2 balance cost and capabilities.

What desktop printers come closest to commercial PCB production quality?

High-end laser milling hybrid printers like the LPKF ProtoMat S104 offer close to commercial board quality and feature sizes. The Nano Dimension DragonFly also produces professional grade boards through additive inkjet printing.
