3D Prototyping: Rapid Prototyping

3D prototype printing (rapid prototyping) is a technology that allows three-dimensional objects to be created from a digital model. Thanks to 3D prototype printing, it is possible to quickly produce design models and small series of objects with great precision and without expensive equipment or time-consuming manual work. This is a real revolution in how objects are produced and can potentially change how we live and work. In this respect, FAMA 3D is one of the most reliable companies in the industry and has the most extensive catalogue available to small and large customers. But first, let’s find out why 3D printing is so useful and what this new technology’s many uses and applications can be.

How 3D printing works for prototyping

3D prototype printing creates thin layers of material, usually plastic or metal, stacked on top of each other until the desired object is formed. Each layer is created using a nozzle that releases the molten material, which is then solidified using heat or a UV lamp.

The process of 3D printing begins with the creation of a digital model of the object you want to make using 3D modelling software; after the prototype is created, it is converted into a printer-readable format and sent to the printing device; once the impulse is received, you begin to make the object, starting from the bottom of the printing chamber and working upwards. The nozzle moves the melted material to the desired position, thus creating the first layer of the object. When the first layer is solidified, the printer creates the second layer, overlapping the material until the product is complete.

3D printing is precise and fast, allowing complex objects to be created with great fidelity to the original model. However, the printing speed depends on the size and complexity of the product to be made, the material used, and the printing technology in use. Fama 3D prints are made using modern technologies that guarantee a higher production speed than the production times of prints offered by similar companies.

Multijet Fusion MJF: operation and applications

MultiJet Fusion (MJF) is a 3D printing technology developed by HP that creates three-dimensional objects with great precision and surface quality.

This technology creates thin layers of powdered plastic or metal material, which are superimposed on each other to form the desired object. Unlike other types of 3D printing, which use a nozzle to release the molten material, MJF technology uses a system of inkjets that heat the powder of the chosen material to high temperatures, causing it to melt and solidify.

The MJF printing process begins with creating a digital model using 3D modelling software. This software converts the model into a format readable by the printer producing it.

MJF technology is particularly suitable for producing small series of objects with excellent dimensional accuracy and surface quality. It can also create objects in assorted shapes and sizes, making it suitable for various applications.

However, this mechanism also has some disadvantages compared to other 3D printing technologies. For example, it is less fast than other printing techniques and requires specific material powders, which must be loaded into the device before printing can begin. Finally, it is not suitable for producing objects of considerable size.

SLA resin printing: operation and applications

SLA (stereolithography) resin printing is a 3D printing technology that enables the creation of precise, high-quality three-dimensional objects.

This technology works through a UV light beam that solidifies photosensitive resin in a printing chamber. A glass plate is immersed in a tank of photosensitive resin, and the UV light beam is projected onto the surface of the resin, solidifying it and creating the object’s first layer. Once the first layer has been made, the plate is raised a few microns and repeated until the prototype is complete. This type of printing can be more expensive than other technologies due to the cost of the resin and the need to use an enclosed printing chamber, but it is the ideal solution when you want to produce precise, high-quality products.

Direct Extrusion: operation and applications

Direct extrusion is another 3D printing technology that enables the creation of three-dimensional objects from molten plastic.

This technology uses a nozzle that releases the material at the desired position, thus creating an initial layer; once the base is created and solidifies, the printer starts to create the other layers.

Direct extrusion is a popular 3D printing technology in many fields, from engineering to construction. It is particularly suitable for the production of large objects and the creation of plastic prototypes.

Direct extrusion also has some disadvantages compared to other 3D printing technologies. For instance, it is less precise, can produce objects with lower surface quality, and requires specific material filaments to be inserted into the printer before the process starts. Despite these limitations, especially in creating small parts, it excels in larger works and serves as an excellent alternative to other 3D printing processes.

The printing technologies offered by Fama 3D

In the preceding paragraphs, we have delved into some of the 3D printing techniques and the various possible applications and uses of this technology, but to obtain quality objects, it is important to rely on serious and safe companies such as Fama 3D.

Fama 3D specialises in 3D prototype printing and offers its customers production techniques such as MJF multijet fusion technology, SLA resin printing, LPBF metal printing, and direct extrusion among the main services, but also counts on a wide range of tailor-made services that can be customised according to customer requirements.

For example, specific materials are crucial for achieving a quality print. The next paragraph lists all the products that can be used in 3D printing and are available in the Fama 3D catalogue.

Materials for 3D printing

Four main materials can be used for 3D printing: plastic, metal, rubber, and resin. These are then divided into smaller sub-categories and used independently in 3D printing.

Fama 3D offers polyethylene (PE), polypropylene (PP), polycarbonate (PC), ABS (acrylonitrile butadiene styrene), and PETG (polyethylene terephthalate glycol) as plastic materials. These materials are suitable for producing everyday objects such as toys, small electrical appliances, and household accessories.

Fama 3D also offers a selection of metallic materials, such as stainless steel, titanium, and aluminium, for producing mechanical parts and precision components.

In addition, Fama 3D offers a variety of rubber and resin materials, such as silicone rubber and photopolymer resins, which can be used to produce rubber prototypes and create models for jewellery and art objects.

New applications of 3D printing: construction, real estate and jewellery

3D printing can create houses and building components such as walls, roofs and floors. Several printing technologies, such as SLA resin printing, direct extrusion and LPBF metal 3D printing, can be used.

Depending on the user’s needs, print houses are made in different sizes and shapes. They can be used as permanent or temporary homes in urban or rural areas.

3D printing offers numerous advantages in building construction. It allows for customising interiors and adding aesthetic or practical details while saving time and materials compared to traditional construction methods. In addition, printed houses can be built with eco-friendly materials, helping to reduce environmental impact.

Of course, there are also some disadvantages to using this technology, such as the printing speed, which can be slower than traditional construction technologies, or the cost or lower durability.

Nevertheless, 3D printing can be a viable alternative for creating houses and house components, but it is important to carefully weigh the pros and cons of this technique before using it.

3D printing can also be used in the real estate sector and is often used to create furniture and furniture components, such as chairs, tables, wardrobes, and beds. Due to its flexibility and adaptability, customised objects and furniture can be created quickly.

One of the latest applications of 3D printing is in the field of jewellery, as it can be used to create jewellery such as rings, earrings, bracelets and necklaces. This technology makes it possible to create jewellery of all kinds and to experiment with shapes and sizes that were previously unimaginable.
