BARS Inc. envisioned a fully automated pizza vending machine — touchscreen order, robotic assembly, cooked in minutes. We designed the concept that raised their funding, then built the 20-foot machine: fridge, convection oven, warmer, lid placer, and conveyors as one line, with PLC controls, custom electronics, and admin and customer software. The working machine secured a $300,000 round and press coverage.

Automated pizza vending machine at a glance
| Industry | Food automation / vending |
|---|---|
| Scope | Machine design, mechanism and controls, large-scale rapid prototyping |
| Product | Automated pizza cooking and vending system |
| Outcome | Working machine, $300,000 funding round, press coverage |
| Typical timeline | 6-12 months for a full-size automated machine |
The problem: a restaurant process, unattended, in a cabinet
An automated pizza vending machine has to store ingredients at safe temperatures, handle dough without tearing it, cook to a repeatable result, and hand a hot product to a stranger with no staff present. Every one of those steps is a mechanism, a sensor and a failure mode.
What large-scale rapid prototyping made possible
Full-size printed and fabricated parts let BARS test motion, clearances and the cook cycle on real hardware within weeks instead of arguing over CAD. We iterated the handling mechanism and the control sequence on the machine itself, then documented the build so it could be reproduced.
Outcome
The demonstrable machine did what renderings never do - it raised a $300,000 round and earned media coverage, because investors could watch it make a pizza.
Frequently asked questions
What does an automated vending machine prototype cost?
Full-size food automation prototypes generally start around $75,000 and scale with the number of mechanisms and the food-safety requirements.
Can you build machines larger than a standard 3D printer bed?
Yes - large-scale rapid prototyping combines big-format printing with fabricated frames and off-the-shelf motion hardware.
Do you handle the controls and software?
Yes. Controls, sensors, HMI and the cook sequence are engineered alongside the mechanics.
Capabilities used on this project

How a 20-foot automated pizza machine got prototyped under one roof
Concept design that raised the funding
Before any build, BARS needed a product concept to present to investors. We designed it from the client's vision of how the machine should perform and look; the funding it raised financed full development.
Mechanical line: five machines acting as one
The 6' wide, 7' tall, 20' long system combines a fridge, convection oven, warmer, lid-placing machine, and conveyors connecting every unit into a single automated line. We 3D printed plastic parts and produced all metal and electronic components in-house.
Electronics, PLC programming, and calibration
We selected components, designed the electrical schematic, and programmed the PLC plus the admin and customer-facing control software. Then we assembled, tested, and calibrated the full-scale prototype until it hit the desired operational efficiency.

Questions about this project

Talk to an engineerWhat is large-scale rapid prototyping?
Building full-size working machines, fast. For BARS that meant a 6-by-7-by-20-foot automated pizza line — mechanical systems, electronics, PLC and software — designed, printed, fabricated, assembled, and calibrated by one team.
Can a prototype help raise investment?
Twice over, here: the concept design raised the development funding, and the working machine then anchored the $300,000 round. Acting as the client's technical arm, we explained feasibility directly to investors.
Who builds the software for an automated machine?
We did — the PLC programming plus both the admin and customer sides of the operation control, as part of the same engagement as the mechanical and electrical design.
How long does a full-size automated machine take?
Six to twelve months for a machine of this class, from concept through a calibrated, operational full-scale prototype.
