Frequently asked questions

• What design files and tools do I need to print a PCB with Voltera?

  Voltera’s prototyping workflow begins with a digital circuit design created in your ECAD tool. This design is exported as a Gerber file — the industry-standard format for defining trace layouts, drill holes, and solder paste placement. 

  The basic printing process works like this:

  1. Design your circuit in an ECAD tool
  2. Export your design as a supported file type:

  • V-One supports Gerber files
  • NOVA supports Gerber and SVG (beta feature)

  3. Upload the file to Voltera’s software
  4. The system automatically maps the substrate height using a built-in probe
  5. The software guides you through ink calibration based on your selected material and settings
  6. The printer builds the circuit, layer by layer, directly onto the substrate

  Voltera’s software handles parsing, mapping, and calibration based on your input files and selected materials, enabling a seamless transition from digital designs to physical circuits.

  It's important to note that Voltera’s systems are designed for additive prototyping only — they do not support traditional copper etching or subtractive manufacturing processes. If you're transitioning from subtractive workflows, our circuit design guide can help you adjust your designs for additive printing.

• Can I use additive prototyping to test integrated components?

  Yes. Additive prototyping works well for testing passive and active electronic components like resistors, capacitors, sensors, and microcontrollers. It’s a valuable tool during the early design phase to verify circuit behavior before committing to a PCB assembly or full production. Keep in mind that more complex integration — especially for high-speed or analog circuits — may require additional validation steps using traditional PCBs.
• Can additive PCB prototyping support multilayer circuit designs?

  Yes — but capabilities depend on the system. V-One is well-suited for single- and double-sided designs on rigid substrates, while NOVA supports advanced stack-ups and flexible materials for multilayer circuits or rigid-flex PCBs. Material compatibility and alignment remain key considerations for complex builds. If you're unsure which system fits your needs, Voltera’s team can help.
• What’s the difference between additive and subtractive PCB prototyping?

  Additive PCB prototyping builds circuits layer by layer, applying conductive inks directly to a substrate without removing material. This contrasts with subtractive methods, which etch away copper from a board to create copper layers. Additive techniques are especially useful for rapid iteration, as they avoid the setup and waste associated with traditional PCB fabrication. While subtractive processes can achieve higher conductivity, additive methods offer greater design flexibility and are more sustainable for small-batch R&D.
