# A closed loop for discovering new materials. [Concept visualisation · credits](https://prism.mirdyne.com/impressum/#credits) In-silico optimisation. Robotic synthesis. Extreme validation. PRISM, our first product, finds the material. Then we make it, qualify it and scale it into production. [Register interest](https://prism.mirdyne.com/interest/) [The problem](https://prism.mirdyne.com/#gap) [![Hessen Ideen Wettbewerb 2026 – KI‑Sonderpreis von hessian.AI](https://prism.mirdyne.com/awards/ki-sonderpreis-badge.png)](https://prism.mirdyne.com/news/) - Funded by **The European Space Agency** First proof of the loop - First run **Refractory alloys** ESA FLPP, PRISM Alpha - Next **PFAS-free polymers (planned)** Seeking funding PRISM Alpha, with - European Space Agency - Bimo Tech - ArianeGroup - Fraunhofer IAPT - amsight The problem ## Materials decide what we can build. Finding new materials has become faster. Putting one into service still takes ten to twenty years, the figure in the 2011 US Materials Genome Initiative white paper. This count is an example: refractory alloys. - **474,311,376** possible alloys from just five of nine high-melting metals - **÷10** alloys a day, an assumption, not a measurement - **≈130,000** years, if that assumed rate held every day **Nobody can make them all,** so PRISM picks the few worth making. *How we counted:* Example: refractory alloys. 126 ways to pick five of nine metals that all melt above 1,650 °C, × 3,764,376 ways to mix five in whole percent. Ten a day is an assumption, not a measurement, so the year count that follows from it is not a result. Each dot is 20,000 alloys; their positions are illustrative. 10 to 20 years: US Materials Genome Initiative, June 2011. Run 01 — first proof of the loop (ESA FLPP, PRISM Alpha) ## The first loop, run on real metal. *Photos:* 01 to 05 are drawn. 06 to 10 and 14 are our own photographs. 11 and 12 show the same steps in other labs, until we have our own; 13 is drawn. - Diagram: A specification sheet beside a thermometer: what the part must survive. 01 Your requirementWhat the part must survive, and what it has to beat. - Diagram: A stack of papers under a magnifying glass: the literature on the requirement. 02 PRISM reads the literaturePapers and data on your requirement, with their sources. - Diagram: Four classes of material as tags; the two worth researching are marked. 03 Classes worth researchingThe families of material that could meet it. - Diagram: A network of choices: from an empty start, our models build recipes step by step, and more of the flow reaches the better ones. 04 Our generative models propose recipesThey build each recipe step by step; the better a recipe, the more of the flow reaches it. - Diagram: Several models score each candidate. Where they agree on a good score, the candidate goes on; where they disagree, an exact calculation decides. 05 The best few are chosenSeveral models judge each one; where they disagree, an exact calculation decides. - ![Small pieces of raw metal spread out on a paper towel before a melt.](https://prism.mirdyne.com/img/spark-charge.webp) 06 Raw metals, ready to melt - ![Close-up of a copper hearth: small pieces of raw metal loaded into its hollows.](https://prism.mirdyne.com/img/spark-hearth-charge-sq.webp) 07 Loaded into the hearth - ![Looking through the viewport of an arc-melting furnace: a small alloy button glows orange inside.](https://prism.mirdyne.com/img/spark-melt.webp) 08 Melted with an electric arc - ![A cast alloy button with a crystalline surface pattern, resting in a red lid on a lab bench.](https://prism.mirdyne.com/img/spark-button.webp) 09 An alloy button, as cast - ![A metal block being milled down: bright curled chips cover it, with milled channels beside them.](https://prism.mirdyne.com/img/machining.webp) 10 Milled down - ![Metal powder for 3D printing under an electron microscope: tiny, almost perfect spheres.](https://prism.mirdyne.com/img/route-powder.webp) 11 Made into powder - ![Through the tinted safety window of a laser powder-bed printer: small test pieces stand in the metal powder they were printed from.](https://prism.mirdyne.com/img/route-powder-bed.webp) 12 Printed in a powder bedLPBF: research at Fraunhofer IAPT, industrial at Bimo Tech. - Diagram: A nozzle blows metal powder into a laser beam and builds the part up, bead by bead. 13 Or built up by DEDDirected energy deposition. - ![A small round test coupon held between two fingers in the lab at IPPT PAN, Warsaw.](https://prism.mirdyne.com/img/ippt-coupon.webp) 14 Coupons, then testsDensity and flaws first, then real conditions.

For some critical raw materials, the EU relies almost entirely on one country. - **65%** By 2030, the EU wants no more than this share of any strategic raw material to come from one outside country. - **SX500** No existing alloy could survive inside SpaceX’s Raptor engine, so SpaceX made its own. We design new alloys in Giessen, and Bimo Tech makes them in Wrocław. *Sources:* EU Critical Raw Materials Act, Regulation (EU) 2024/1252, recital 12 and Article 5.

Polymers are planned, and we are seeking funding for that run. 01 / 07 **Requirement** Prototype Diagram: The PRISM loop: your requirement in the middle; research, design, screen, make, test and learn around it, and round again. **You tell us** the heat and loads the part faces, and the material it has to beat. 1. 01 Requirement Prototype **You tell us** the heat and loads the part faces, and the material it has to beat. 2. 02 Research Prototype **PRISM reads the literature** on your requirement, and we pick the classes of material worth researching. 3. 03 Design Prototype **Our generative models propose** a whole batch of promising recipes in those classes, not one best guess. 4. 04 Screen Prototype **Several models judge each one,** an exact calculation settles the doubtful ones, and most ideas stop here. 5. 05 Make In use **We melt the best candidates,** mill them down, turn them into powder and print them by laser powder bed fusion or DED. 6. 06 Test In use **We measure** each sample against your targets. 7. 07 Learn Prototype **Every result** goes back into the models and decides what we try next. Diagram: The PRISM loop: a requirement, then research, design, screen, make and test; every result goes back to design. Evidence is recorded at every step. What must the part survive? **You tell us** the heat and loads the part faces, and the material it has to beat. Prototype Roadmap ## Three stages. Today, and next. Stage 1 runs today. Stage 2 runs today through our partners, and the next step automates it. Stage 3 is the goal. 01 Live ### Stage 1 · In silico PRISM runs today: literature, generative models, scoring and exact calculations, inside the ESA projects SPARK and PRISM Alpha. 02 Today ### Stage 2 · Physical synthesis Today the samples are made with partners: arc melting at the WUST lab in Wrocław, laser powder bed fusion at Fraunhofer IAPT, industrial printing at Bimo Tech, and testing at IPPT PAN. Next: automated, robotic synthesis. 03 Goal ### Stage 3 · Own qualification rigs Robot-controlled rigs that test to failure and qualify materials in the environment they are made for, so the loop learns from measurements nobody else has. This is the goal. Testing today uses partner equipment. How we compare ## Not software. Not a consultancy. A closed-loop accelerator.
