REF / Technical & Compliance

The technical questions,
answered straight.

Engineers, inspectors and developers ask us the same things. Here are direct answers on the technology, the materials, the structural engineering and how this gets permitted — no hand-waving.

01The basics

What exactly does Vertis 3D deliver?
We deliver a printed structural frame — a monolithic reinforced-concrete shell — printed on your site. We don't sell printers and we don't take over your project. Your architects, engineers and finishing trades work exactly as they always have; we simply handle the most labor-intensive phase faster. This is Construction-as-a-Service, not a hardware purchase.
Is the finished building anything unusual or experimental?
No — and that's the point. What you hand the inspector is ordinary reinforced concrete: the same material the industry has trusted for over a century. The printing process changes how the frame is formed, not what it is made of. There are no exotic composites and no "first-of-its-kind" material to get approved.
Where are you currently able to build?
We have secured permits for 3D-printed structures across Texas, California, Virginia, Florida, Montana and New York, and have validated the system abroad on government projects in Southeast Asia. Because the end product is conventional concrete, new jurisdictions are an engineering-and-permitting exercise, not a technology approval.

02Materials & technology

What is actually being printed — and with what?
A monolithic dual-wall system with integrated columns and beams, printed in cementitious mortar. The cavities are then filled with conventional concrete and rebar per your engineer's specs. We formulate on-site using local aggregates plus a small dosage of our proprietary additive — which eliminates the shipping cost and supply-chain fragility of trucking proprietary materials to your site. ON-SITE BATCHINGLOCAL AGGREGATE
How precise is the print, and how fast?
The gantry prints to ±0.5 mm dimensional precision at roughly 25–30 m² of wall per day, within a print envelope up to 30 m × 60 m. In practice that translates to a 3–4× faster structural phase than conventional framing. ±0.5 MM30M × 60M ENVELOPE
What role does AI / computer vision play?
Computer vision watches every layer as it is deposited — verifying dimensional accuracy, flagging deviations before they compound, and writing a complete quality trail used for PE certification and permitting. It is a safety-and-quality system built in-house, not a gimmick: it earns its place by holding the highest safety standard on real builds.
Do I need proprietary software or special file formats?
No. Standard CAD/BIM in, machine code out. Our slicer converts your drawings to print instructions. Your architects design the way they already do — there are no proprietary formats and no retraining required.

03Structural & engineering

How strong is the structure?
Cavity walls are filled with 40 MPa (≈5,000+ PSI) concrete — the same grade used in bridges and high-rises. The result is a monolithic reinforced-concrete structure with a design service life of 140+ years. 40 MPa5,000+ PSI140+ YR LIFE
Is it seismic-rated?
Yes. The monolithic shear-wall geometry is well suited to seismic loading, and structures are engineered to the relevant seismic provisions for each jurisdiction. As with any building, the governing seismic design is finalised by the project's engineer of record and reflected in the PE-stamped plans.
Who stamps the engineering?
A licensed professional engineer. Every project is delivered with PE-stamped plans demonstrating code equivalence, so the structure is certified the same way any reinforced-concrete building is.
How is it tested?
Concrete strength is verified to ASTM C39/C39M (compressive strength of cylindrical specimens), alongside the layer-by-layer computer-vision record. Printed wall systems are evaluated against ICC-ES AC509, the acceptance criteria for 3D-printed concrete walls. ASTM C39/C39MICC-ES AC509

04Code & compliance

How does a 3D-printed building get permitted?
Through the IBC's alternative-methods (performance) path, supported by ICC-ES AC509 and PE-stamped plans that demonstrate the printed walls meet or exceed the equivalent prescriptive requirements. Because the end product is conventional reinforced concrete, this is a well-trodden path — not an experimental exemption. IBC PERFORMANCE PATH
Is there regulatory risk in adopting this?
Minimal — and that's deliberate. There are no experimental exemptions to chase and no novel material to get approved. Because the inspector receives ordinary reinforced concrete, it passes the way concrete always has. The speed is upside; the adoption risk that usually accompanies new construction technology is largely engineered out.
Which standards and codes apply?
Primarily ICC-ES AC509 (3D-printed concrete walls), the IBC performance path for alternative methods, and ASTM C39/C39M for concrete strength — all backed by PE-stamped documentation. Local amendments are addressed jurisdiction-by-jurisdiction during permitting.

05Process & logistics

How long does it take to get set up on site?
The gantry ships in standard containers and is set up and running in under 24 hours, operated by a 2–3 person crew — replacing the 6–8 person masonry teams traditional framing requires. <24 HR SETUP2–3 CREW
What's the four-step process?
1 · Design integration — upload standard CAD/BIM; our slicer produces machine code. 2 · Rapid deployment — containerised gantry on-site in under a day. 3 · Printing — monolithic dual walls printed to millimetre precision with channels for MEP rough-in. 4 · Conventional completion — fill, rebar, MEP and finishing proceed exactly as on any build. Your trades just start sooner.
Has this held up in tough field conditions?
Yes — the system has been stress-tested under monsoon conditions, going from foundation to occupancy-ready frame in under 90 days with a 2–3 person crew. Every visible ridge in the finished wall is structural concrete.
How much waste does it produce?
As an additive process, it places material only where the design needs it — cutting construction waste by roughly 60% versus conventional formed-and-poured methods. ~60% LESS WASTE

06Working together

Do I have to buy a printer or train a team?
No. There is no capital expenditure on hardware and no training investment. We deploy our gantry and crew; you get a finished structural frame on time, on spec and on budget. You stay focused on what you already do well.
Will this disrupt my existing workflow?
No. We integrate into your workflow rather than replacing it. The gantry runs with platform-agnostic concrete pumps already found on most job sites, and your architects, engineers and finishing trades carry on unchanged.
Who is this for?
Developers and contractors who want a faster, lower-labor structural phase without becoming a robotics company — and real-estate investors who understand that timeline compression is margin. If you build with concrete, this fits the way you already work.
