U4Prototyping & 3D printing
A working sample in weeks.
We build a prototype you can hold and try where it will live: on a dev board, on a first circuit board, and in an enclosure from the 3D printer. A sample asks better questions than any presentation.
- Dev boards
- First circuit boards
- 3D-printed enclosures
What we solve
When people call us about a prototype
01
You need to show the idea
To an investor, a customer or your own team. A working sample says more than slides.
02
You do not know if it is feasible
A quick dev-board sample answers the riskiest question before a serious budget is spent.
03
The enclosure does not fit
We print it, try the assembly and the seals, and fix the model before an injection mould is ordered.
04
You need a few units for a pilot
We assemble a handful of samples for testing by real users in the real environment.
What you get
A sample and everything for the next version.
A prototype answers a question. Besides the device, you get the files to carry on from there.
| Document | Format | Note |
|---|---|---|
| Working sample | Device | Tested in conditions close to real |
| Sample schematic | Source files + PDF | The basis for the next version |
| Enclosure model | STEP + STL | For printing or injection moulding |
| Sample firmware | Source code | With flashing instructions |
| Test notes | What worked and what to change |
What we work with
- 3D printing (FDM)
- PLA · PETG
- Fusion 360
- ESP32 dev boards
How it runs
Five steps to a sample in your hands
- 01
The question
What the sample must prove, and to whom.
2-3 days
- 02
Quick sample
A dev board, modules and first firmware.
1-3 weeks
- 03
First board
A schematic and a circuit board sized for the enclosure.
2-4 weeks
- 04
Enclosure
Model, print, trial assembly and corrections.
1-2 weeks
- 05
Testing
On site, with the people who will use it.
1-2 weeks
Durations depend on complexity and on parts delivery. We flag parts with long lead times up front.
Proof
A prototype in a public space
NSpot is a working prototype: it has stood in the Sea Garden in Varna for years, and every step is documented, from the structure to the electrics.
Questions about prototypes
How quickly can there be a sample?
A quick dev-board sample usually takes one to three weeks. With a circuit board and an enclosure, between four and eight weeks, depending on complexity and parts delivery.
Which materials do you print with?
Most often PLA and PETG for enclosures and fixings. For parts outdoors or near heat we choose the material for the conditions.
Can I bring you just the idea?
Yes. We start with a conversation about what the sample must prove, and work towards the simplest sample that answers it.
What happens after the prototype?
You decide: a next version, a short run or a pause. You get all the files whatever you choose.
