Creating a realistic layout of appliances from available materials is a task that requires precision, patience and an understanding of engineering principles. When it comes to the project βwashing machine of paperβ, many imagine childrenβs crafts, but a professional approach to this issue allows you to create full-fledged prototypes for exhibitions, tutorials or design sketches. Paper prototype allows you to visualize the dimensions and ergonomics of the device before the start of expensive production.
In this guide, we will look at the process of creating a detailed model that will not just be a box with a drawing, but a functional layout with opening elements and simulate an internal device. You will need to stock up on dense cardboard, quality paper for printing textures and a set of cutting tools. Accuracy of cutting It is a key factor influencing the final appearance of the product.
Why paper and cardboard? These materials allow you to quickly make adjustments to the design, test various options for the layout of the nodes and demonstrate the principle of the mechanisms in the section. The main purpose of creating a paper model is to test the ergonomics and visual perception of the design in life size without the cost of casting plastic or metal. Let's start preparing the materials.
Selection of materials and tools for layout
To create a durable and beautiful model of the washing machine, you need to choose the right basic materials. Conventional office paper is not suitable for load-bearing structures, as it quickly deforms under its own weight and glue. The main material should be binding-board 1 to 2 millimeters thick or corrugated board with a fine wave, if greater rigidity of the body is required.
In addition to the basics, you will need specialized tools for processing edges and connecting parts. Scissors can crease cardboard, so the use of a sharp stationery knife with interchangeable blades is a prerequisite. You will also need a metal ruler, a cutting mat and a quality glue that does not deform the paper when drying.
- π¦ Binding cardboard with a density of 300-500 g / m2 for the case
- βοΈ Stationery knife with spare blades and metal ruler
- π§΄ PVA carpentry or polyurethane glue for cardboard gluing
- π¨ Photo paper or matte paper for printing textures and interface
Particular attention should be paid to the choice of glue. For gluing paper textures, glue spray is ideal, which is applied evenly and does not create bumps. To connect the power elements of the frame, it is better to use a thick PVA or a specialized glue for modeling, which provides rigid fixation.
Development of the drawing and sweep of the body
Before you pick up a knife, you need to create an accurate drawing of the future washing machine. Standard dimensions of the front machine are 60x60x85 cm, but for a desktop model, these proportions can be scaled, for example, 1: 5 or 1: 10. It's important to proportions between height, width and depth to make the layout look realistic.
The sweep of the body is a flat scheme, which after bending along the lines turns into a three-dimensional figure. When designing a sweep, it is necessary to lay technological valves for bonding. These valves are usually 10-15 mm wide and are located on the ends of parts that will be hidden inside the structure or in corners.
To create a digital layout, you can use graphic editors or specialized 3D modeling programs that allow you to automatically get a scan. If you work by hand, use millimeter paper to build a life-size sketch. Precision of angles 90 degrees is critical to ensure that the finished model does not sway.
The Secret to Perfect Corners
To obtain perfectly smooth folds on the cardboard without cracks, run along the line of folding with the blunt side of the knife or an empty ballpoint pen with moderate pressure, without cutting through the top layer of cardboard. This will create a groove along which the material will fold exactly.
Assembling the force frame and walls
The assembly process begins with the creation of an internal frame that will hold the shape of the entire structure. Cut all parts according to the sweep, observing maximum accuracy at the corners. Do not rush to glue all sides at once; first collect the main planes: front, back, side and upper cover.
Connection of parts is better to produce in two stages. First, glue the side walls to the bottom, making sure they stand strictly perpendicular. Use corners or heavy objects for fixation until the glue is completely dry. Then the rear wall and the upper cover are inserted into the structure. Frame rigidity It depends on the quality of the angular joints.
| Element of construction | Materials | Thickness | Note |
|---|---|---|---|
| Carrier frame | Corrugated cardboard (3 layers) | 3 mm | It provides strength. |
| Decorative panels | Binding cardboard | 1.5 mm | For a flat surface |
| Imitation of a drum | Tight paper | 0.3 mm | Curl up into a cylinder. |
| The door of the hatch | Plastic or cardboard | 2 mm | It needs reinforcement. |
After assembly of the main box it is necessary to allow the structure to dry for several hours under the press to exclude deformation. If you use corrugated cardboard, make sure that the direction of the waves in neighboring parts is perpendicular to each other β this will significantly increase the strength of the product.
βοΈ Screening of the frame
Facade design and hatch construction
The most recognizable part of any washing machine is its facade with a round loading hatch. To create a realistic hatch, you need to cut a round hole in the front panel and make a simulation of glass and rim. You can use transparent plastic from the packaging or even the bottom of a plastic bottle to simulate tinted glass.
The rim of the hatch (cuff) is made of a strip of cardboard twisted into a ring and glued around the hole. To make it smooth, use the papier-mache technique or paste the ring with thin paper in several layers, grinding irregularities after drying. Loops You can simulate using small pieces of wire or draw them if the door is not planned to open.
β οΈ Warning: When cutting out a round hatch hole, be extremely careful not to damage the side walls of the case. Better to cut short than cut too much.
The control panel is located in the upper right part of the facade. It can be printed on a high-resolution color printer and pasted on top of cardboard. To simulate buttons, you can use three-dimensional elements, for example, halves of beads or cut out of foamed PVC circles, which give the layout a tactile realism.
To create the effect of a chrome hatch rim, use self-adhesive foil or a special metallized scotch tape, gently gluing it in a circle.
Details: drum, tray and legs
The interior space also requires attention, especially if the model was conceived with the door opening. The washing machine drum can be made from a sheet of dense paper rolled into a cylinder with perforation (holes). Perforation is easiest to do with a skin puncher or a thin stitch before the cylinder is twisted.
The powder tray (dispenser) is an important element that is often missed. It can be pushed out of the case, made of several layers of cardboard. Inside the tray, it is worth denoting zones for different types of detergents, drawing the appropriate symbols. The legs of the washing machine They should be adjustable in reality, but in the layout it is enough to make them stable and even so that the model does not swing.
- π The drum must have a characteristic texture and holes.
- π§΄ The washing tray must be extended or detailed
- π¦Ά The legs should ensure a stable position of the model on the table
- π Imitation of the power cord will add realism (you can use a twisted cord)
To create the effect of metal legs, you can use bottle caps painted with silver paint, or twisted foil tubes. The main thing is that they are the same height, otherwise the βpaper washing machineβ will look skewed, which will spoil the overall impression of the work.
Finishing and surface protection
The final stage is bringing the model into the marketable form. All the joints of cardboard, even the most neat, can be noticeable. They must be splashed with a special paper putty or a mixture of PVA glue with chalk, and then sanded with small sandpaper. This will create a monolithic plastic effect.
After grinding, the model can be painted with acrylic paints from aerosol can. White gloss is a classic color for washing machines, but modern models are both silver and black. Apply the paint in thin layers from a distance of 20-30 cm to avoid leaks. Lacquer coating It protects the paper from moisture and abrasion.
β οΈ Before applying the finishing varnish, make sure that the paint is completely dried, otherwise chemical reactions may occur and the surface will wrinkle.
To give shine to plastic elements (control panels, hatch) you can use a transparent glossy varnish. Matte surfaces of the case, on the contrary, it is better to cover with a matte fixator to remove the shine of the paper and make the model more similar to the factory product.
The quality finish hides the paper-based origin of the model, making it indistinguishable from a plastic prototype at a distance.
How to make a rotating drum in a paper model?
To create a rotating drum, use a wooden skewer or wire as an axis. Pass the axle through the center of the drum and fix it in holes on the side walls of the body. For the drum to rotate freely, the holes in the walls should be slightly larger than the diameter of the axis, and the drum itself should not touch the walls of the body.
How to replace a special glue for modeling?
If there is no special glue, you can use thick PVA glue (construction or carpentry), diluted with a minimum amount of water. For gluing paper with cardboard is also well suited glue pencil UHU or similar quality analogues that do not soak the paper.
Can I make a working washing machine out of paper?
A fully functioning machine with water heating and an electric motor made of paper cannot be made because of the risks of fire and soaking. However, it is possible to create a kinetic model where the drum is rotated by hand or from a simple mechanical transmission, simulating the washing process.
What is the best size for a school project?
For a school project, the optimal scale is 1: 5 or 1: 4. In this case, the height of the model will be about 15-20 cm, which is enough for detailing small elements, but does not require a huge amount of material and storage space.
