Why Choose Akriti Over NVIS 72A?
6 critical advantages for PCB prototyping professionals and production labs
prototype larger boards, panel arrays, or multiple designs simultaneously in one run.
thicker materials, taller fixtures, and greater versatility beyond just PCB work.
— twice as fine. Critical for dense analog, RF, and high-speed digital PCB designs.
— 0.73 kW, 24,000 RPM, ER20 collet with standard 14mm max shaft diameter bits.
4030 is certified for 24/7 operations — designed for production floors, not just lab
prototyping.
FlatCAM + GSender/UGS — compatible with SolidWorks, Fusion 360, CATIA. No software lock-in,
ever.

🏆 Verdict: Akriti Wins 14 of 20 Categories vs NVIS 72A
The Nvis 72A has two genuine advantages: automatic surface levelling (very useful for warped PCBs)
and a significantly smaller, lighter footprint at 28kg and 432×320mm. If lab space is extremely
constrained, or if auto-levelling is a hard requirement, NVIS has merit.
For everything else — work area, Z-travel, spindle quality, trace width, travel speed,
warranty, certifications, and software openness — Akriti PCBProto 4030 is the stronger
choice. And critically, Akriti is ISO 9001 + CE certified, which is often a mandatory procurement
criterion for engineering colleges, defence labs, and corporate R&D facilities where NVIS 72A may
fall short.
Akriti certifies that all components marked as Made-in-India are sourced from
verified Indian manufacturers.
