Specification

Description:Field of the invention
The present invention relates to the field of construction materials, specifically to the development of doors and windows for residential buildings using 3D printing technology. The invention particularly involves the integration of plastic waste into cement concrete mixtures to create eco-friendly, durable, and cost-effective doors and windows.
SUMMARY
The present invention discloses a method for developing doors and windows for residential buildings using 3D printing technology and a cement concrete mixture that incorporates plastic waste. The process involves the preparation of a specialized mixture containing cement, aggregates, plastic waste, and additives suitable for 3D printing. The doors and windows are designed using CAD software, and the mixture is extruded layer by layer to form the final product.
The integration of plastic waste into the cement concrete mixture not only helps in reducing the environmental burden of plastic pollution but also enhances the performance of the final product by improving thermal insulation and making it lightweight. The 3D printing process allows for design flexibility, enabling the creation of customized door and window shapes to suit different architectural styles and requirements.
DETAILED DESCRIPTION
The growing concern over plastic waste pollution has led to increased interest in sustainable construction practices. Plastic waste, if not properly managed, can cause significant environmental harm. Concurrently, there is a high demand for cost-effective, durable building materials that can support sustainable construction initiatives.
Traditional doors and windows in residential buildings are often made from wood, metal, or conventional concrete. However, these materials are either depleting natural resources or are energy-intensive to produce. Furthermore, traditional production processes involve significant labor and time.
3D printing technology, also known as additive manufacturing, offers a novel approach to building construction by providing flexibility in design, reducing material waste, and speeding up production times. The integration of plastic waste into cement concrete mixtures for the construction of doors and windows represents a sustainable solution for reducing plastic waste while producing durable and energy-efficient building components.
The present invention aims to utilize 3D printing technology to produce doors and windows using a cement concrete mixture that incorporates plastic waste, providing a sustainable alternative for residential construction.
Object of the Invention:
1. To develop a method for producing cement concrete doors and windows for residential buildings using 3D printing technology and incorporating plastic waste into the concrete mixture.
2. To reduce plastic waste by repurposing it as a component in construction materials.
3. To offer an eco-friendly, durable, and cost-effective solution for residential doors and windows.
4. To improve the speed and efficiency of manufacturing doors and windows by using 3D printing technology.
5. To create doors and windows with enhanced mechanical properties, including strength, thermal insulation, and resistance to environmental factors.

Detailed Description of the Invention:
1. Materials:
The mixture used for 3D printing doors and windows consists of the following components:
• Cement: Acts as the primary binding material.
• Aggregates: Fine and coarse aggregates provide structural strength.
• Plastic Waste: Recycled plastic waste (e.g., polyethylene, polypropylene) is shredded into small particles and mixed with the cementitious material to enhance insulation and reduce weight.
• Admixtures: Chemical additives that improve workability, durability, and flowability of the mixture.
• Water: Added in precise quantities to achieve the desired consistency for 3D printing.
2. 3D Printing Process:
The process begins with the design of doors and windows using CAD software. The design is translated into a format that can be read by the 3D printer.
• Layer-by-Layer Deposition: The cement concrete mixture, containing plastic waste, is deposited layer by layer using a 3D printer. The printer follows the design's geometry, building up the structure of the door or window frame.
• Curing: After printing, the doors and windows are allowed to cure under controlled conditions to achieve maximum strength.
3. Design Considerations:
The design of the doors and windows can be customized based on the requirements of the residential building. The 3D printing process allows for intricate designs, including frames, panels, and decorative elements, that would be difficult to achieve with traditional methods.
• Thermal Insulation: The inclusion of plastic waste in the cement concrete mixture enhances the thermal insulation properties of the doors and windows, helping to improve energy efficiency in the building.
• Lightweight Structure: The plastic content reduces the overall weight of the doors and windows, making them easier to install and transport.
• Durability: The mixture is designed to provide enhanced resistance to environmental factors such as moisture, UV exposure, and temperature fluctuations.
