Concrete 3D Printing Patents: Who Leads, Where the Gaps Are 2026
Concrete Rheology Control for 3D Printing: Patents Shaping Buildability and Interlayer Bond
Filing activity peaked in 2021 at 84 records, then fell 68% to 27 by 2024 — the last year the dataset treats as complete, since publication lags filing by about 18 months. Filings rose from 18 in 2017 to a peak of 84 in 2021, then dropped 68% to 27 by 2024 — the last year the dataset can treat as complete. Readers should not read 2025-2026 figures as confirming a continued decline; they are still being filled in as publications catch up with filing dates.

Common questions about this landscape
Who are the leading patent holders in 3D concrete printing?
The ranking covers 72 companies, and it is led by a single assignee holding 88 of the 264 records in scope, well ahead of the fifth-place holder at 10 and tenth place at 6. The top 5 assignees combined account for 57.2% of all records, and the top 10 account for 70.5%, so filing activity is concentrated rather than evenly spread. The leaders include cement and admixture majors alongside a specialist construction-printing company and several universities, reflecting that both materials and machinery sides of the field are actively claimed.
Is patent filing in 3D concrete printing still growing?
Filing volume rose steadily to a peak of 84 records in 2021, then fell 68% to 27 by 2024, the most recent year the dataset treats as complete. This looks like a cooling from an early filing surge rather than sustained growth, though publication lag of roughly 18 months means 2025 and 2026 figures are still incomplete and should not be read as confirming further decline. A clearer picture of the 2025-2026 trend will only emerge once those publications catch up.
What technology areas get the most patent coverage?
Cement and refractory chemistry, classified under C04B, appears in 69.3% of the 264 records, making it the most heavily claimed area. Shaping of clay and cement products (B28B) and dedicated additive-manufacturing classifications (B33Y) follow at 40.5% and 36.4% respectively. Mortar and concrete mixing equipment (B28C), by contrast, sits at only 3.4%, suggesting the hardware that actually controls mix consistency during printing is comparatively under-claimed relative to the chemistry.
Disclaimer. This analysis is based on Patsnap Eureka data drawn from a limited snapshot of global patent records and is provided for general information and reference only. Patent data carries inherent limitations — recent filings are under-counted because of publication lag, counts may be on a record or family basis, classification and applicant-name data may contain errors or duplicates, and the underlying search query defines the scope shown — so the analysis may be incomplete or inaccurate and may not reflect the full technology landscape.
Nothing here is an exhaustive prior-art, novelty, freedom-to-operate or validity search, nor does it constitute legal, financial or professional advice, and it should not be relied upon as such. Verify independently and review with qualified patent and legal professionals before acting on it.
Method: Filing trend and technology composition. Derived from a Patsnap search on Concrete Rheology Control for 3D Printing covering 2015–2026, data cut-off 2026-07-31.
