PhosPrint, founded in 2019 as a spin-off of the Institute of Communication and Computer Systems at the National Technical University of Athens, builds a laser bioprinter that deposits living cells directly onto tissue during surgery. Its first target is bladder cancer patients whose bladder is removed and rebuilt from intestine: the printer coats the intestinal tissue with the patient's own bladder cells to avoid the mucus, metabolic problems and stones that such neobladders cause, according to CORDIS.
The European Innovation Council granted €2,000,560 towards a €2.86 million project from May 2023 to April 2026. The report covering the first 18 months says a 12-pig study "validated the safety and superiority" of the approach against the standard neobladder, that a clinical version of the printer was ready for first-in-human use, and that the patent portfolio grew from four to five families. In December 2025 Corallia Ventures and Google Maps co-founder Lars Rasmussen put €500,000 into the company. The European Medicines Agency and Greece's medicines agency approved a first human trial, which PhosPrint said in May 2026 "is beginning". No human results have been published.

Where PhosPrint Stands Now
According to ICCS, the regulators treated the product as a combination of cell therapy and medical device, and the submission ran to more than 7,000 pages. PhosPrint's CEO said the seed money would mainly cover the costs of the first human trial, and that proving safety is a prerequisite for follow-on investment. In May 2026 PhosPrint received a start-up award from the Athens Chamber of Commerce and said the trial was starting at Laiko and Gennimatas hospitals in Athens, according to its announcement.
"D-LIB treated animals at 2 months post-surgery, were free from mucus and metabolic defects, in sharp contrast to controls that developed all known side-effects."
PhosPrint, report to the EICThe Technology: Printing Cells With Light
The printer uses laser-induced forward transfer: a laser pulse pushes tiny droplets of cell-laden material onto a surface with high precision. A biopsy is taken from the patient, bladder cells are isolated and expanded in the lab, and during surgery they are printed onto the stripped intestinal lining that forms the new bladder. The report says 17 pig surgeries were used to refine the protocol before the 12-animal study. The pig results appear only in company reports and statements so far.
What the EIC Project Promised, and What CORDIS Shows
The project promised to introduce laser bioprinting into surgery, starting with bladder reconstruction. It delivered a clinical-grade device, completed preclinical validation and set up a quality system for EU and US regulators. The human trial only started around the project's end, so clinical validation is still to come. CORDIS still lists the project as signed.

The Money
The report records that Corallia Ventures offered a €4 million pre-money valuation to open negotiations and that a crowdfunding platform, Capital Cell, planned to host a round of up to €500,000. The round that closed in December 2025 raised €500,000. PhosPrint has not published its revenue or losses.
What Cannot Be Checked
Questions for the EIC
How many patients the trial will enrol, when results are expected, whether the Capital Cell round happened and why CORDIS shows no final report are not public.
Why Europe Should Care
More than 150,000 patients a year worldwide are candidates for bladder removal due to cancer, according to Corallia. The EIC grant carried a small Greek company from animal studies to a regulator-approved human trial.
What the project promised
Laser bioprinting introduced into surgery, starting with bladder reconstruction for cancer patients.
What the record shows
A clinical device, successful pig studies, an approved first human trial and a €500,000 seed round.
The Verdict
Into the clinic, results pending
PhosPrint used the EIC grant to reach a first human trial, a real milestone for a company its size. Whether printing cells inside patients works as it did in pigs is the question the trial has yet to answer.
