Insoles have the opposite problem: volume. A practice fits pairs every week and chooses between a laboratory's catalogue shape and a €25,000 printer of its own.
Every option a clinic has today solves half the problem.

A free month to try it.Set up in an afternoon; the first parts are free.
From scan to print. Every value is the practitioner's.
Scan input
The limb, checked and measured.
The scan is cleaned, aligned and measured. A file the studio cannot design on is refused, and it says why. The practitioner signs the step.
Cavity volume
2,122cm³
Height
279mm
Trimline
The rim, drawn on the limb.
On this socket the rim is measured every 2 degrees. The studio's house trimline is a cut like this one, measured off one of our production sockets.
Rim points
180
Popliteal cut
92.1mm
Wall
Typed by the prosthetist, measured by us.
This socket was asked for a 4 mm wall, 6 mm at the distal end. The studio never proposes a wall thickness: it measures the wall it built at every vertex, and says "not measured" rather than guess.
Median wall
5.13mm
5th percentile
3.98mm
Block
A block to bolt to.
The distal end is solid: a plate with rounded corners that widens as it rises and turns round, a pocket for a steel insert at each corner, and a hole in the centre. Measured on this socket.
Plate
70.1mm
Pockets on a square of
36mm
Inserts
Four steel inserts.
A stainless steel insert screws into each pocket: M12 outside, where it grips the printed wall, and M6 inside, where the adapter's screws go. The screws thread into steel, never into the print.
Outside
M12
Inside
M6
Adapter
The adapter, screwed on.
A four-hole pyramid adapter sits flat on the plate over the inserts, held by four stainless M6 screws. Its pyramid is where the pylon and the foot join, and where the alignment is set.
Screws
4 × M6
Adapter
4-hole
Print export
One body, ready for the farm.
Printed in our own foamed carbon-fibre polyamide, about 23 per cent less dense than the solid material, and delivered with its inserts seated. The export carries its report.

Arch height.
In millimetres, the same step at every size. The surface that moved glows, then settles.

The fit gate.
Minimum thickness, wall angle, watertight and manifold are checked before a design can become an order. Left and right are mirrored to 0.0000 mm.
A pressure plate or a 3D foot scan is analysed in memory and never stored. The 3D scan proposes only the measured shape, never a correction.

Diaco sold them to four clinics in Iran at the local price, about €4 to €9 a pair; 359 are invoiced. Most went to our co-founder's Faramarz clinic and about 50 to the Red Crescent rehabilitation clinic whose O&P section he runs. It proves production and clinical use, not a European price.
One socket, worn daily since June 2026.
470 g in its latest version, against an estimated 670 g for a carbon laminate. It carried the ISO 10328 P6 load level in an informal test; the accredited test runs in year one. Three more are in production for the Red Crescent clinic.

Year-one average prices, after material, energy, packaging, shipping, labour, depreciation and the site. A machine-hour on a socket earns about three times a machine-hour on an insole.

productive hours a machine-month: 12 hours a day at 75 per cent. Our insole machines ran 7 to 9 hours a day in September, limited by orders.
Independents first, with a free month.
M7 to M9
Pilot
Five practices and workshops. The software set up in an afternoon, the team trained, insoles and check sockets made free.
Each pilot
Prove
A pilot passes on written criteria, set before it starts, and yields a case note either way.
M10 to M12
Convert
Three of five pilots convert. Seven to nine paying clinics by month 12, and the first definitive sockets.
Years 2 and 3
Grow
Five new clinics a month in year two, ten in year three. Chains in phase two, through licensed farms.

pilots converting to paying clinics in M10 to M12, the plan's target
Where first
Brabant and Limburg, a day's drive from the farm, then the Randstad. For sockets, rehabilitation workshops such as Rijndam, De Hoogstraat and Roessingh.
How we reach them
A Dutch clinical sales lead hired before the pilots and a Dutch clinical adviser; NVvP and ISPO-NL meetings; OTWorld in year two.
Built for the MDR from the first line.
The software
Our documented position: class I medical device software under Rule 11.
A written classification opinion before the pilots; the declaration, EUDAMED registration and a PRRC before any clinic uses it.
It proposes no clinical value. The wall is typed by the prosthetist; every export says approval is the practitioner's.
The part
A custom-made device. The clinic stays the manufacturer and issues the Annex XIII statement.
We fabricate to its approved design under a written agreement, the central-fabrication model of European O&P.
Definitive sockets only after the accredited ISO 10328 report. Check sockets from the farm's opening.
Patient data
Servers in the EU. The clinic controls the record; we process it under a data-processing agreement.
A data protection impact assessment and a security review before the pilots.
With a local installation the record stays on the clinic's computer, and only an order leaves it.
The base case.Self-declared before the first pilot: €45k of regulatory work in year one, ISO 13485 certification in year two.
The software waits for a notified body.Clinics design in the CAD they use today and send us files; the farms keep manufacturing under the same agreement. About a year and the certification cost are added.

After the pre-seed, cash stays at about two months of operating cost at its lowest: about €99k, in month 15, just before the seed.
At half the clinic rate, cash stays positive and break-even moves into year four.
Base case of the financial model, all inputs on one sheet. Year one runs from arrival (M1) to M12, with farm one open in M7.
€600k pre-seed, closing by month four.
Farm one: twelve machines in Eindhoven, built with their CE declaration.
The team: the three founders, a Dutch clinical sales lead and a farm operator.
The regulatory start: classification opinion, technical file, accredited ISO 10328 test.
Five free pilots with written success criteria.

Three founders: machines, clinic, operations.
Omid Ghazi
Co-founder, chief executive and chief technology officer
Chemical engineer; designing and building industrial 3D printers since 2014.
Founded Diaco in 2016: more than 400 industrial machines delivered, production farms of up to 30 machines, more than 1,500 production projects for some 30 companies and 12 universities.
Wrote Farm Manager, PrintFlow and Avesta Studio; developed the foamed carbon-fibre polyamide process and the layer-direction slicing strategy.
The three founders move to Eindhoven with their families and run Avesta Care full time.
Reza Khodakarim, chief clinical officer
Orthotist and prosthetist. Founded the Faramarz clinic in Shiraz in 2017, which fits our insoles and socket, and has run the O&P section of the Red Crescent rehabilitation clinic there since 2019.
Sajjad Seyedzadeh, chief operating officer
Founded the Nafis mattress factory in 2016 and grew it to 20 employees under five team leaders: production, purchasing, delivery and finance.
A Dutch clinical adviser
A prosthetist or podotherapist of standing, on board before the pre-seed: the Dutch clinical terms, the first pilot doors, the advisory board.
