This is the technology that has already revolutionized a number of industries and is currently rocking the construction industry. For construction professionals and tech enthusiast knowledge, this guide will provide you with the knowledge needed to understand how 3D printing used in construction is reshaping the future of the construction industry.
We’ll go deep into the application of 3D printing in construction in this comprehensive guide and discuss the benefits of 3D printing and the future of 3D printing in construction.
What is 3D Printing in Construction?
Impression 3D is a process of printing three-dimensional objects through the use of additive layers of materials according to digital designs. In building, we can use a 3D printer to make building parts or even a complete building. In contrast to the traditional construction techniques where they use manual labor and huge machinery, 3D printing is rapid, economical, and sustainable.
How 3D Printing Used in Construction Works?
Understand how 3D printing works in the construction industry and enables architectural designs to come to life.
Step 1: Design Creation
The process of 3d printing in construction begins with a 3D design of the structure, which is usually created with CAD (Computer-Aided Design) software. Special software is used by architects and engineers to design with the complex details and precision of structures.
Step 2: Material Selection
After the design is prepared, it is followed by the selection of the suitable material. Construction additive printers are usually used with concrete, thermoplastic or special 3D printing materials that are structural integrity printers.
Step 3: Printing the Structure
The 3D printer reads the digital model and the printing begins layer by layer. Depending on the size and complexity of the structure under construction, the process may be completed within a few hours or a number of days.
Step 4: Post-Processing
After printing, the structure may require finishing touches such as strengthening, sanding or incorporation of other elements such as windows, doors and plumbing.
Materials for 3D Printing in Construction
The construction materials used in 3D printing are very important in determining the level of strength, durability and sustainability of the structure made. Various materials have been used over the years to fit various forms of 3D printing technologies.
Concrete and Concrete-Based Materials
In 3D printing, concrete is the most common material of construction. Concrete is mixed using specialized formulations and can be combined with additives to enhance their flow, strength, and curing time.
- 3D Printed Concrete: This material is developed with the express purpose of additive manufacturing, often with properties adapted to hold the forces of the building structures.
- Geopolymer Concrete: Geopolymer concrete is an environmentally-friendly substitute of normal concrete and is produced by using industrial wastes such as fly ash and slag.
Plastiques
ABS (Acrylonitrile Butadiene Styrene) and PLA (Polylactic Acid) plastics are the most commonly used plastics in smaller scale or prototype projects.
- ABS : ABS is the strongest and flexible material that is commonly utilized in prototyping and other smaller-scale construction components such as decoration, brackets, or furniture.
- PLA : PLA is a renewable biodegradable plastic authored out of corn starch. It is commonly applied in architecture to models or prototype pieces.
Metal Alloys
In 3D printing metal alloys are being actively developed as construction materials, particularly within sectors such as infrastructure or custom components where high strength is required.
- Acier inoxydable : Stainless steel is very common in structural and architectural elements, it is highly strong and durable.
- Aluminium : Aluminum is a lightweight, strong and corrosion-resistant material that is used in construction as non-structural or a lightweight alternative.
Céramique
Specific applications are made in ceramic materials, especially in finer parts, advanced design or other specialized features such as insulation.
- 3D Printed Ceramics: Ceramics may be employed to create such components as tiles, cladding, or architectural elements, which can be valuable and attractive
Composites and Advanced Materials
Composite materials that are produced by combining various materials are also being actively used in 3D printing in construction because it provides strength and flexibility.
- Carbon Fiber Composites: Materials that are infused with carbon fiber are very light and are commonly used in the construction industry where the aspect of weight reduction is crucial.
- Fiberglass: Fiberglass is a typical composite material that is highly strong in terms of weight-to-weight ratio and this material used in construction either as a structural or non-structural component.
