Efficiency: The machine can lay down concrete in layers, building four square meters of wall per hour.
Speed: More than three times faster than conventional building methods when constructing sophisticated architecture.
Resource Efficiency: Requires less material and fewer workers, making it a cleaner option compared to traditional construction methods.
Personnel: Only three workers needed:
One operates the 3D printer.
One manages the mixing machine.
One oversees operations and performs minor tasks.
Construction Site Management
Responsibilities:
Site manager oversees concrete mixer operations and manages office work via smartphone.
Anchors are attached at intervals to support double walls.
3D printer operations are monitored on a computer screen.
3D Printing Process
Design Collaboration: Architects design with input from construction team, focusing on feasibility.
File Preparation:
Design converted to a step file.
Step file is sliced to obtain a g code.
G code sent to printer to start construction.
Building Specifications
Construction: Building is 54m long, 11m wide, and 9m high.
Functionality: No windows needed as it will house computer servers.
Development: Utilizes a BOD2 3D printer by Danish company COBOD.
Traditional and Modern Mix: Cement ceilings poured conventionally.
Architectural and Financial Aspects
Innovation: Largest and highest 3D printed building designed by architect Jan Falkman.
Experimentation: Opportunity to test new methods within simple architectural guidelines.
Investment: Total cost of 2.5 million euros including land.
Profitability: Transition to 3D printing aimed for economic viability.
Future of 3D Printing in Construction
Growth Prospects: Expected to transition from experimental to commercial phase.
Personal Preferences: Site manager prefers 3D printing over conventional methods and plans to continue in this field.
Market Trends: Contracts secured for next two years.
Conclusion
3D printing in construction is proving to be an efficient, innovative, and economically viable alternative to traditional construction methods, with significant potential for market expansion.
