What is 3D printing and how does it work?
3D printing, also known as additive manufacturing or rapid prototyping, is a process of creating three-dimensional objects by building them layer by layer using a 3D printer. The process starts with the creation of a 3D model using computer-aided design (CAD) software. This software is used to create a digital representation of the object, which is then saved in a format that can be read by the 3D printer. The digital file is then sent to the 3D printer, which reads the instructions and uses them to physically build the object layer by layer.
One of the advantages of 3D printing is that it allows for the creation of very complex shapes and geometries that would be difficult or impossible to construct by hand. This is because the 3D printer can build the object in a precise and controlled manner, layer by layer, until the final object is complete.
3D printing can be done with a variety of materials, including plastics, powders, ceramics, metals, and even organic matter such as tissue cells or food. The specific process used to build the object will vary depending on the material being used. For example, some 3D printers use a process called extrusion, where material is pushed through a nozzle and deposited in layers to form the object. Other 3D printers use processes such as powder bed fusion or binder jetting, which use heat or a binder to fuse the layers together.
There are many websites that offer a wide range of digital file templates for 3D printing, which can be used to create a wide variety of objects. From toys and figurines to functional parts and even clothing, the possibilities are virtually endless. Check out our guide on the best repositories of free 3D printing models and design files.

Applications for 3D printing
Industrial applications of additive manufacturing are now common in the aerospace and car and industries. For instance, Airbus says that its A350 XWB model includes over 1000 components manufactured by 3D printing. It even installed titanium 3D-printed parts into serial production aircraft.
Apart from the rapidly growing hobby market, 3D printing is finding more and more use in medicine, dentistry and biotechnology to produce customized prosthetics and implants, and to generate bio-matter for purposes such as skin grafts. For instance, 3D bioprinting is an advanced and sophisticated additive manufacturing technique that attempts to recapitulate the native architecture of tissues through precise deposition of cell-containing hydrogel bioinks.
3D printing technologies are used in the food industry, including fabricating food for people with chewing and swallowing difficulties and as part of novelty, decorative and gourmet food offerings. Numerous food products are candidates for 3D printing, such as crackers, pasta, pizza and chocolate. Novameat, a Spanish food-tech startup, 3D-prints vegan meat imitation from peas, rice, seaweed, and some other ingredients that were laid down criss-cross, imitating the intracellular proteins:
3D fabricated objects that are anatomical replicas of whole or parts of people’s bodies are used in medical and patient education and for planning surgery.
3D printing is employed by archaeologists cultural heritage practitioners and museums to fabricate replacements for ancient artifacts and create virtual experiences or mementos for visitors.
Types and accuracy of 3D printing technologies
Choosing a specific 3D printing processes depends on the intended purpose. For instance, prototypes are made with FDM printing and complex objects are made with selective laser sintering.
Fused deposition modeling (FDM) creates objects by extruding thermoplastics through a heated nozzle. FDM is one of the most common 3D printing processes and is often used to produce quick prototypes or functional parts. Industrial FDM printing has a dimensional tolerance of ± 0.15% and a lower limit of ± 0.2 mm.
Stereolithography (SLA) utilities photopolymerization to create parts. This technology uses the correct light source to interact with the material in a selective manner to cure and solidify a cross section of the object in thin layers. SLA printing produces smooth, visually accurate parts made from cured resin. Industrial SLA printing has a dimensional tolerance of ± 0.15% and a lower limit of ± 0.01 mm.
Selective laser sintering (SLS) is a technology where the material is heated, but not to the point of melting, to create high resolution items. Metal powder is used for direct metal laser sintering while thermoplastic powders are used for selective laser sintering. SLS is often used to produce complex geometries. SLS printing has a dimensional tolerance of ± 0.3% and a lower limit of ± 0.3 mm.
Material jetting is the most accurate 3D printing process because heat is not used in the process and warping and shrinking are therefore not an issue. Material jetting has a dimensional tolerance of ± 0.1% and a lower limit of ± 0.05 mm.
Metal 3D printing works very similarly to other 3D printing processes – metal powders are heated and fused together into layers. Metal printing has a dimensional tolerance of ± 0.1 mm.
Of course, when 3D printing an object, you want to make sure that the final product is as accurate as possible. Dimensional accuracy – i.e. how well a printed object matches the size and specifications of the original file – depends on a number of critical parameters:
Machine accuracy – Manufacturers usually provide standard dimensional accuracies that can be achieved on a well-maintained machine.
Object size – In general, the larger a print objects gets, the more room for manufacturing errors exist.
Materials – Choosing the appropriate material has a big impact on printing accuracy, for instance, standard SLA resin has a high dimensional accuracy compared to flexible SLA resin.
Warping and shrinkage – Large expanses of material, flat surfaces, and unsupported structures can all warp and should be minimized in your final design. Proper cooling procedures are necessary to keep objects in the desired shape.
