Introduction to 3D printing
There are many different 3D printing technologies available, each with its strengths and weaknesses. The most common technology used for consumer-grade 3D printers is fused deposition modeling (FDM), which extrudes melted plastic filament through a nozzle to build up the object. Other popular technologies include stereolithography (SLA), in which layers of photopolymer resin are cured by ultraviolet light; selective laser sintering (SLS), in which a laser fuses together small particles of plastic, metal, or ceramic powder; and direct metal laser sintering (DMLS), in which a laser fuses together small particles of metal powder.
The material you choose for your 3D-printed object will depend on the application and the results you want to achieve. PLA and ABS plastics are the most commonly used materials for FDM 3D printing, while SLA printers typically use photopolymer resins. SLS and DMLS printers can print with a wide variety of materials, including plastics, metals, ceramics, and glass.
If you’re just getting started with 3D printing, we recommend using PLA or ABS plastic. These materials are relatively inexpensive and easy to work with. They can be printed on any type of 3D printer
Types of 3D printing materials
There are multiple types of 3D printing materials, each with its unique characteristics. The three most common categories of 3D printing materials are plastics, metals, and ceramics.
Plastics:
The most common type of 3D printing material is plastic. Plastic filament is fed into the printer, melted, and extruded layer by layer to create the desired object. There are many different types of plastic filaments available, each with its own set of properties. The two most common types of plastic filaments are ABS (acrylonitrile butadiene styrene) and PLA (polylactic acid).
ABS is a strong and durable plastic that is often used in the manufacturing of products such as Lego bricks. However, it has a higher melting point than PLA and can produce fumes that some people find unpleasant. PLA is a biodegradable plastic made from renewable resources such as cornstarch or sugarcane. It has a lower melting point than ABS and does not produce fumes when printed.
Metals:
Another type of 3D printing material is metal. Metal filaments are fed into the printer and melted using a laser or an electron beam. The molten metal is then deposited onto a built platform layer by layer to create the desired object. Unlike plastic filaments, metal filaments must be cooled between layers to prevent them from solidifying prematurely. This makes metal 3D printing slower than plastic 3D printing.
Plastic
When it comes to 3D printing, there are a variety of different materials that can be used. One of the most common materials used in 3D printing is plastic.
Plastic is a versatile material that can be used for a wide range of applications. It is strong and durable, making it ideal for products that need to withstand heavy use. Plastic is also lightweight, making it easy to transport and handle.
There are a variety of different types of plastic, each with its unique properties. The most common type of plastic used in 3D printing is ABS (acrylonitrile butadiene styrene). ABS is a strong and impact-resistant plastic that is widely available in a variety of colors.
Another popular type of plastic used in 3D printing is PLA (polylactic acid). PLA is made from renewable resources, such as cornstarch or sugar cane. It is biodegradable, making it an environmentally friendly option. PLA is available in a variety of colors, including clear and translucent options.
3D-printed plastics can be finished in several ways, such as painting, sanding, or polishing. They can also be machined or drilled just like any other type of plastic product.
Metal
The most common material used in 3D printing is metal. Metal 3D printing uses a process called directed energy deposition to melt and deposit metal powder onto a build platform. This process can be used to create objects from a variety of metals, including stainless steel, aluminum, titanium, and nickel alloys.
Metal 3D printing is an ideal option for creating parts that need to be strong and durable. Metal parts printed using this technology can withstand high temperatures and are resistant to corrosion. Additionally, metal 3D-printed parts can be customized to have specific mechanical properties, such as stiffness or ductility.
One downside of metal 3D printing is that it is a relatively slow process. Additionally, the build platform must be heated to high temperatures during the printing process, which can make the technology unsuitable for some applications.
Ceramic
Ceramic materials are one of the most versatile and widely used materials in additive manufacturing. 3D-printed ceramics can be used for a variety of applications, including medical implants, aerospace components, and consumer goods. Ceramic materials have a wide range of properties that make them well-suited for 3D printing, including high strength, durability, and resistance to heat and chemicals.
Ceramic materials can be difficult to work with, however, due to their brittle nature. It is important to use the proper type of ceramic material for your application to ensure that it will withstand the forces it will encounter during use.
Wood & Paper
There are a few key things to consider when selecting the right material for your 3D printing project. Wood and paper are two popular choices for 3D printing, but each has its unique benefits and drawbacks.
Wood is a strong and durable material that can be used for a variety of applications. However, it is also one of the more expensive materials to print with. Paper is a cheaper alternative to wood, but it is not as durable or sturdy. When choosing between wood and paper, it is important to consider the final application of the product. If you need a strong and durable product, wood may be the better choice. If you are looking for a cheaper option, paper may be the way to go.
There are a few key benefits to using each type of 3D printing material:
PLA: Polylactic Acid is one of the most popular materials used in 3D printing. It is made from renewable resources like corn starch, making it a more eco-friendly option. PLA is also biodegradable, so it won’t clog up landfills. This material is best for low-temperature applications and prints with a smooth finish.
ABS: Acrylonitrile Butadiene Styrene is another widely used 3D printing material. It is stronger and more durable than PLA, making it ideal for products that will be subject to wear and tear. ABS can also be heat-resistant, so it can be used for applications where high temperatures are a concern. However, this material does require higher printing temperatures and can produce fumes that are harmful to breathe in.
NYLON: Nylon is a versatile 3D printing material that can be used for a variety of applications. It has a smooth surface finish and is strong and durable. Nylon can also withstand high temperatures and is resistant to chemicals and solvents. One downside of nylon is that it can be difficult to print with because it tends to warp during the cooling process.
