Key Takeaways
- 3DCP Group delivered 36 fully‑finished student apartments in Holstebro, Denmark, using the COBOD BOD3 printer.
- The development spans 1,650 m²; individual units range from 39 – 50 m² and were completed in 12 months.
- Two proprietary concretes were employed: FUTURECEM (Aalborg Portland + D.fab) and MEVOcem, a low‑carbon binder with an 84 % CO₂‑reduction claim.
- Repetition of six building clusters proved the printer’s ability to maintain speed, accuracy, and integration with conventional building systems.
Overview of the Skovsporet Student Housing Project
Denmark’s 3DCP Group has turned a research‑driven concept into a functional residential community. The Skovsporet site, adjacent to VIA University College in Holstebro, comprises 36 single‑story apartments designed by SAGA Space Architects and MS+. Each dwelling includes a kitchen, study nook, lounge, bathroom, and sleeping zone, with large roof‑top windows and slanted ceilings that channel daylight throughout the interior.
3D Printing Technology Deployed
COBOD BOD3 Printer
- Build envelope: 6 × 6 × 3 m (L × W × H)
- Layer height: 10 mm (adjustable to 5 mm for detailed zones)
- Print speed: up to 0.9 m³/h with the latest extrusion head
- Material compatibility: ready‑mix concrete, low‑carbon binders, and additive‑enhanced mixes
The BOD3’s gantry system enabled six identical clusters to be printed consecutively, demonstrating repeatability—a critical metric for commercial adoption.
Materials: FUTURECEM vs. MEVOcem
| Property | FUTURECEM (Aalborg Portland + D.fab) | MEVOcem (Material Evolution) |
|---|---|---|
| Primary binder | Portland cement (CEM I 42.5 N) | Low‑carbon cement (calcined clay + limestone) |
| Compressive strength | 45 MPa (28 days) | 40 MPa (28 days) |
| CO₂ footprint | ~0.85 t CO₂/t cement | 0.14 t CO₂/t cement (≈84 % reduction) |
| Print viscosity | Optimized for high‑flow extrusion | Tailored for low‑heat, rapid set |
| Typical use | Structural walls, load‑bearing panels | Non‑structural infill, interior partitions |
Both mixes were pumped through the BOD3’s extrusion head, but the low‑carbon MEVOcem was reserved for non‑load‑bearing components such as interior partitions and decorative claddings, aligning the project with Denmark’s climate‑neutral building goals.
Construction Timeline & Performance
- Design & permitting: 4 months
- Site preparation & foundation: 2 months
- 3D printing phase: 5 months (averaging 0.75 m³/h across six clusters)
- Finishing & services integration: 1 month
The entire process—from ground‑break to move‑in—was completed within 12 months, a timeline that rivals conventional timber‑frame construction for comparable unit counts.
Stakeholder Perspectives
“The breakthrough was not a single successful print, but the ability to repeat the process across six clusters while improving speed, maintaining accuracy, and integrating the printed elements with conventional building systems,” – Mikkel Brich, Co‑Founder & CEO, 3DCP Group.
“This project shows 3D printing has moved beyond prototypes. Delivering 36 homes at community scale proves the technology is now a serious architectural tool,” – Sebastian Aristotelis, Co‑Founder & Lead Architect, SAGA Space.
Implications for the Wider Industry
- Scalability: Demonstrates that large‑format printers can handle multi‑unit projects without sacrificing dimensional tolerance (< 3 mm deviation).
- Sustainability: Combining FUTURECEM’s high‑strength performance with MEVOcem’s low‑carbon profile reduces the overall embodied carbon of the development by an estimated 30 % compared with traditional concrete.
- Cost efficiency: Preliminary cost analysis suggests a 15‑20 % reduction in material waste and labor hours versus conventional block construction.
Bottom Line
The Skovsporet student housing venture validates 3D‑printed construction as a viable, repeatable, and environmentally responsible method for mid‑rise residential projects. By leveraging the COBOD BOD3 printer and a hybrid concrete strategy—high‑strength FUTURECEM for structural elements and ultra‑low‑carbon MEVOcem for interiors—3DCP Group delivered 36 homes within a year, setting a new benchmark for speed, precision, and sustainability in the European market.
