What Is 3D Printing? An Easy Explanation

3D Printing allows you to create products without having to produce a mold. It is easier to make iterations of the product and there is no need for expensive machining.

There are different types of 3D print: melting, stereolithography and sintering. These processes are usually carried out using lasers, plasma arches or electron beams.

Rapid Prototyping

Rapid prototyping is a key component in product development. 3D Technix revolutionizes how products are designed, launched and conceived. It allows designers to create prototypes quickly and cost-effectively, execute quick revisions based on real-world testing, and get feedback from end users before the product goes into production. The result is an accelerated design process, cost savings of up to 50% and the ability for designers to create customised product without having to redesign the entire product.

3D printing is an effective and efficient tool for rapid prototyping. It is suitable for a variety of applications including consumer electronics, automotive, healthcare, and medical. Each industry has specific requirements for prototyping, but they all benefit from this technology’s speed and flexibility.

There are a number of different 3D printing technologies that can be used for rapid prototyping. Each has its own benefits and disadvantages. When choosing a 3D printing method, it is important to consider the project requirements. For example, whether the prototypes will be used as a form or if they will serve a function. Also, what material compatibility you need is also incredibly important. Cost, fidelity level, and the development stage are all important factors. Moreover, it’s important to understand how tolerance, accuracy, and precision work in the 3D printing process.

High-fidelity prototypes are ideal for visualizing and testing final parts before manufacturing. This type of prototyping can be done using any CAD file with a finish that mimics how the final part will look and feel. However, these models are not ideal for testing the functionality of the part. In addition, they may require a lot of post processing, such as sanding and painting, which can add to the overall cost of the project.

Low-fidelity prototypes can be more useful than their high-fidelity equivalents. They’re also a good way to evaluate form and fit. They can be used for a variety of purposes, including product demonstrations, sizing and ergonomic testing, and communication with customers. They can also be used to help engineers evaluate a new design’s performance under real-world conditions, and identify any potential problems before it is put into full production. In addition, they can help developers save time and money by avoiding costly mistakes in the manufacturing phase.

Additive Manufacturing

The 3D printing technology is improving and becoming more cost-effective for the production of parts and products. This is due to the advancement of materials and the expiration of patents. But it’s also due to the fact that 3D printing reduces components needed to build an entire product.

A digital model is created first. This model is then “sliced”, into layers which are printed one by one on a 3D Printer. The software that slices the model scans each layer, and then tells the 3D printer how to move the printer so that it can recreate that specific section.

3D printing can use a wide variety of materials, from metals and ceramics to thermoplastics such as acrylonitrile-butadiene-styrene. Some printers use powder bed fusion technologies, such as selective laser sintering (SLS), electron beam melting (EBM) or multi jet fusion (3D-printing with multiple laser sources). Other printers use material extrusion techniques that squeeze heated material through a hot nozzle and onto a buildplate, layer by layer. The stereolithography printers use UV light to cure photopolymer materials.

Printing additive manufacturing allows for the production of consumer products such as eyewear and accessories like jewelry, footwear, and other accessories. In addition, the fabrication of architectural models and prototypes is a common application for additive manufacturing. Buildings and bridges can be constructed by printing concrete in modular sections, which are then assembled on the site.

In aerospace, automotive and industrial machinery applications, the ability to quickly produce complex geometries in durable, lightweight materials is a major benefit of 3D printing. This can save money and time by reducing the requirement for assembly, fixtures and jigs, or by replacing worn out components with a design that is optimized to its intended use.

3D printing has a significant impact on the healthcare sector. From splints and N95 masks to ventilation systems, 3D-printing is helping hospitals and manufacturers improve efficiency and patient safety. It can even be used to create hearing aids that are customized for each patient.

Material Selection

A wide range of materials can be used in 3D printing. The type of material used will depend on desired physical properties and the capabilities provided by the printer.

The most commonly used 3D printing materials are plastics. The most popular is ABS (acrylonitrile butadiene styrene), which is very durable and can withstand heat and impacts. It also has good flexural strength. Another option is polyamide 12, which has high tensile strength and good chemical resistance.

PLA is another plastic filament that comes in many colors and can be used to print intricate details. It is an excellent choice for functional prototypes and concept models. For prints that require more durability, consider using Tough PLA. This is a stronger variant of PLA which can be used to test and trial functional designs. If you want a material which can withstand higher temperature, try nylon or CPE filaments. These materials are able to withstand temperatures up to 110 degC.

Metal is becoming more popular for 3D printing. This is done using a process known as direct metal laser sintering, or Selective Laser Sintering. This method involves heating metal powder in a laser beam, and then hardening it into a shaped part. This method can produce parts with a much higher strength than metals refined conventionally. Stainless steel, aluminum and titanium are some of the metals that are commonly used for this purpose.

While the selection of available materials is expanding rapidly, not all of them are suitable for every application. Some materials require extensive processing after printing and can clog standard nozzles. In these situations, a nozzle designed for this purpose can be used. Similarly, certain fillers can reduce the strength of printed parts. Carbon fiber can enhance the strength of a plastic, but can also cause nozzle clogging or wear.

Understanding the application of the part will be the most important consideration when choosing a printing medium. The rule of thumb is to select a material that’s compatible with the manufacturing method. If you want to print an object with a high tensile force, for example, choose a material like PEEK, PEKK, or PET-G (with 3DGence machines).

Cost

3D printing is a cheaper alternative to traditional manufacturing methods. The initial investment in 3D printing is less than CNC milling. Also, there are fewer costs associated with the process, such as electricity or machine downtime. Costs of materials and labor also decrease. In addition, the process is a single step, reducing energy consumption. The printing process can also be automated, reducing the number of operators required.

The cost of 3D printing is dependent on the type of printer used and the materials used. Professional FDM and SLS printers begin at around $10,000, while consumer and hobbyist printers cost less than $500. The cost of raw material for each print varies depending on the manufacturer. However, it is typically lower than that of other manufacturing processes.

3D printing offers designers the ability to create more iterations, and improve designs faster than traditional prototyping. This can reduce costly design revisions that cause delays in production. It can also save you money by removing the need for expensive physical prototypes.

3D printing allows for a great deal of customization. It can produce complex geometries and lattices that would be difficult or impossible to manufacture using traditional methods, as well as internal cavities and voids. This allows the production of medical devices and custom products, such as dental implant and prosthetics.

3D printing has another benefit: it can be done locally. This can reduce shipping costs and reduce the environmental impact. This may be particularly beneficial for manufacturers of consumer goods or medical devices, which need to be distributed globally.

Formlabs created a calculator that allows users to estimate the cost of printing an object more accurately. The calculator takes into account factors such as material cost, build time and electricity costs, along with the price of the printer. The calculator can be customized and supports both filament and resin 3D printing as well as different scenarios, including commercial and individual uses.s
