3D printing, which is an additive method that creates three-dimensional objects from digital files, is a process where the objects can be printed. The process involves laying down layers of material to create the object. This process creates complex shapes using materials such as metal, ceramic, and plastic.
It is incredible how easy it is to create any kind of three-dimensional object using thin layers.
Choosing the Right 3D Printing Technology for your Business
3D printing has many advantages, but each process is unique and will have its own benefits and limitations.
There are many factors to consider when choosing the right 3D printing software. These include budget, cost of parts and raw material, as well as the production process.
Fused Deposition Modeling, Stereolithography (SLA), Selective Laser Sintering(SLS), and metal deposition are all options at the production level.
Every production process uses different materials, and each will produce different results.
You will also need to carefully assess issues like the material required, desired characteristics of the end product in terms of accuracy, build size, and application.
What are the Benefits of 3D printing?
Easier Customization
Because 3D printing allows quick prototyping and rapid production, it can be a huge asset to your business. 3D printing makes it possible to create and print complex designs, which is a significant advantage over traditional manufacturing processes. This allows you to reduce the complexity and cost associated with customization.
A 3D printer makes it easier to create complex shapes with less effort, time, and material. 3D printing is more efficient than traditional manufacturing methods and doesn’t require specific tools or an initial cost.
All it takes to create a new product is an update of the 3D file. It is possible to make unlimited numbers of identical parts by simply updating your 3D file, as the production cost is the same for any number of 3D-printed parts.
More Eco Friendly
3D printing reduces energy waste and leaves a smaller carbon footprint than traditional manufacturing processes. 3D printing is about affordable products that are efficient and cost-effective. It also aims to reduce waste.
Because 3D is focused on quality and efficiency, it is as eco-friendly a process as you can get.

Common 3D Printing Materials
When creating 3D printed products, there are many options. Our list will help you choose the right material before you make your decision.
Using Plastics for 3D Printing
Plastic 3D models are used often to make prototypes, toys, or household fixtures. Because of their flexibility, firmness, smoothness, and the large variety of colors, they are very popular. They are also relatively inexpensive. There are many options for plastic materials that can be used in 3D printing. Each material has its own unique characteristics and is best suited for specific purposes.
ABS
Acrylonitrile Butadiene Sterene (ABS), is a common polymer that’s used in 3D printing. It is lightweight and has good impact resistance. It is typically printed at a temperature of 210 to 250 deg C (410deg-482deg F). This material is used primarily for making appliances, hulls, decorations, toys, and other small parts. It can be sanded and mixed with acetone to make it smoother or glueable.
PLA
Polylactic acid, also known as Polylactideis (PLA), is a biodegradable plastic made from potatoes, sugarcane, and corn. It is extracted at lower temperatures with a nozzle temperature around 180deg-230degC (356deg – 446degF). It doesn’t require a heated bed, so you can use painter’s tape instead. It’s easy to print, inexpensive, biodegradable, and can be reused for many purposes. It is easy to print on cold surfaces and has low warping. It is more sturdy than other materials but can be damaged by extreme heat.
Nylon
Nylon is known for its toughness and semi-flexibility. It also offers high impact resistance and resistance to abrasion. This is a great material for printing durable parts, textiles, and accessories. This is a great option for complex or delicate geometries. It is also inexpensive and durable, with little warping.
However, it is susceptible to water so it must be dried. Prints may be less accurate due to the possibility of shrinkage during cooling. Nylon filaments require extruder temperatures of between 220-250 oC (428deg – 482degF).
Resin
Another common 3D printing material is this one, which uses plastic resin for the raw material. It is extremely chemical-resistant and has low shrinkage. It can also be printed faster than a filament. It can also be used to create figurines, chess pieces, and rings, as well as accessories and fixtures. Resin is used to print 3D models at temperatures between 200 and 300degC (392deg-572degF). Resin can be expensive
Other Plastics Commonly Used for 3D Printing
- Thermoplastic Polyurethane, also known as TPU (Thermoplastic Polyurethane), is a flexible and abrasion-resistant thermoplastic. It is able to create 3D printed objects with a durable structure that can withstand temperatures up to 80 degrees Celsius (176°F). It can be used to make phone cases, rubber mats, and stress toys.
- PETG, or glycolized Polyester, is a stronger material than ABS and is safe for food. It has very low shrinking. However, it can adhere to the printed surface and be used for food storage containers, packaging, and prosthetic devices.
- ASA has strong chemical and ultraviolet resistance properties. Although it is simple to process, it requires high printing temperatures. It is used often to make bumper covers, garden equipment, fixtures, and other items.
- For 3D printers, PEI (Polyetherimide or ULTEM) is a great choice. The surface, which is amber in color, is resistant to chemical attacks and doesn’t degrade under outdoor conditions. It is ideal for creating ventilation systems, latches, and cable ducts.
Using Metals for 3D Printing
Metal 3D printing (also known as Direct Metal Laser Sintering or DMLS) is a process that uses a laser beam for melting 20-60 microns of metal powder. This allows you to create durable parts out of metal powders. These machines are used to make tool components and final parts for aerospace, automotive, and other industries. These metals can be used to produce parts that are lighter and more affordable.
Aluminum
Aluminum is the most common material used for metal 3D printing. It is mostly used in an alloy form. It has good resistance properties and can withstand high voltages, while still being lightweight. It is used primarily in areas where weight reduction is important, such as the automotive and aeronautics industries.
It allows you to design complex geometries with high levels of detail. Aluminum is ideal for prototyping because it has a melting point of 670°C (1238°F). It is expensive and requires multiple builds to refine a part’s design in order to mass-produce it through 3D metal print.
Stainless Steel
Stainless Steel, another 3D-printed metal material, has a melting point of 1400 degrees Celsius (2552 degrees F). It is ideal for prototyping and demanding projects using a variety of manufacturing techniques. It can also be used in medical industries, such as for the production of custom-made orthopedics.
It is used to make parts in aerospace and automotive industries due to its heat resistance, corrosion-free and abrasion-tolerant properties. It is tedious to print and in some cases, at the microscopic level. However, printed stainless steel can be weak and easily fractured because they are often highly porous.

Other Common 3D Printing Materials
- Ceramic: Ceramics can withstand extreme temperatures and pressure without cracking or warping. Ceramics are less susceptible to corroding and don’t easily wear off, giving them an advantage over plastics and metals. They are ideal for precision work and offer smooth, glossy finishes. They are resistant to heat, acid, and lye. They aren’t the best choice for assembly because they need to be melted at very high temperatures and are fragile.
- Paper3D: printing can be done with paper. You can also print on it to give it a wood-like feel. 3D printed paper does not have the same durability or detail as other materials. It can shrink when it dries, making it difficult to get the exact dimensions.
Food3D: printing can also use food as a material. There are many food products that can be made using 3D printing, including jelly, purees, and cheese. NASA is using this technology to reduce food waste.
An Overview of 3D Printing
3D printing, also known as additive manufacturing (AM), allows you to design an object using the software. The 3D printer then creates it by layering material layer by layer until the object takes shape. You can make the final object using any number or materials, including metals, plastics, powders, and filaments.
3D printing offers many benefits, including short production runs, quick prototyping, quick customization and adaptation, the ability to create complex shapes, and cost-effectiveness. Because it prints parts in layers, 3D printing has revolutionized manufacturing. It allows you to print complex objects with internal structures and subassemblies in one run, which is a significant improvement over traditional methods of production.
This method of producing is also innovative in that the material is not subtracted but is instead added. This means that raw materials are used to construct an object, rather than being removed or scrapped. This allows mass production without the need to use individual tools or hand-crafting. This helps to conserve raw materials and allows for efficient design and production.
In 2020, the global 3D printing market was worth approximately 12.6 billion dollars. Between 2020 and 2023, it is expected to grow at a rate of 17% annually. 3D printing technology has proven to be innovative. It is versatile and can be used in a variety of industries.
3D Printers
3D printers work in the same way as inkjet printers, but create a solid 3D model out of a variety of materials instead of a paper document. 3D printing is a type of additive manufacturing that creates three-dimensional objects from scratch using precision tools and materials. There are many 3D printer software options available, ranging from open-source to industrial-grade. A 3D printer can be used to make almost anything, including toys, machine parts, and jewelry.
These machines are replacing the traditional factory production lines with one machine. You can connect your computer to a 3D printer using a printable file. Once you have printed the file, press “print” to instantly get your 3D print. There are many possibilities for a desktop 3D printer at your company. Although printing speeds will vary depending on the model you are using and the material used, they can still be very fast. It is still a fast way to create parts, prototypes, and other items in a short time.
You can also make high-quality parts for industrial use at a fraction of the price of traditional manufacturing. The ability to modify and innovate your design allows you to create and modify materials as needed. In fact, here is a good selection of the best 3D printers for small businesses in the market today.

3D Printing Technologies for the Best 3D Printed Designs
After you have created your design, it is time to print it! There are many 3D manufacturing options available. The material you want to print on, and the industry for which the product is intended, will determine the method you choose. These are the top 3D printing techniques and their uses.
Fused deposition modeling (FDM)
This is considered to be the most well-known type of additive manufacturing. It works by pushing a filament made of solid plastic or other materials into the hot end. The hot end then extrudes thin streams of molten material in layers to create the desired 3D part. This allows the printer head to control the movement of the layers one at a time, defining the printed shape.
This is used in prototyping and rapid production in various industries such as automotive, manufacturing, medicine, and aeronautics. It uses plastic material for 3D printing, including polymers like ABS, PolyCarbonate(PC), Polylactic acid [PLA], Polyethylene Terephthalate (“PETG”), and others.
Stereolithography (SLA)
This type of additive manufacturing is the most popular. This works by inserting a filament of either solid plastic or other materials into a hot end. To create the desired 3D part, the hot-end extrudes thin streams of molten material in layers. This allows the printer head to control the movement of each layer, thus defining the printed shape.
This process creates fine features and smooth surfaces. This process can be used for manufacturing, including printing custom tools, molds, and jewelry. Stereolithography can be fast and produce any design. However, it can also be costly.
Material jetting (Polyjet)
The process works similarly to inkjet printing, except that it does not lay down the ink on a page. Instead, it deposits layers from one or more print heads. This allows for high-quality, full-color visual prototypes. It can be used for teaching, medical, casting patterns, and making molds.
It is a precise process but it is also one of the most costly 3D printing methods. The parts are not strong and will degrade over time. This allows the creation of electronic devices.
Selective Laser Melting and Selective Laser Sintering (SLM/SLS)
Selective Laser Melting ( SLM ) uses a high-power laser to melt and fuse metallic particles together. This technique is used in a variety of industries, including medical, aerospace, aviation, jewelry, and for melting and fusion of various metals such as titanium, copper, and nickel.
This process can create parts with exceptional physical properties, often stronger than conventional metals, and excellent surface finishes. This is a great advantage for prototyping and tooling.
Binder Jetting
The binder jetting process involves depositing a thin layer (e.g., metal, resin, or ceramic) of powdered material onto the build platform. The adhesive is then dropped onto the build platform. This glue is then deposited by a printer head to bond the particles together. Binder Jetting can be used for many purposes, including creating full-color prototypes and molds as well as low-cost 3D-printed metal parts.
Ceramic and metal are the most common materials used in this process. It is also used in aerospace, medical devices, industrial applications, part casting, and many other uses.
Fused filament fabrication (FFF)
Fused filament fabrication (FFF) is a 3D printing method that uses continuous filaments of a thermoplastic material. The filament is fed through a large spool and deposited on the growing material. This is used for prototyping, rapid manufacturing, medical, machine design, food, and other applications.
This allows you to fuse many materials, including wood, metal-infused thermoplastics and food. Because it uses low-cost materials, this is one of the most affordable 3D printer technologies. You can switch between materials easily and print multiple materials in a quick printing process.
Electronic beam melting (EBM)
The raw metal or wire material is subjected to a vacuum, and then the electron beam heats it together. This hot process produces parts that are free from residual stress. The vacuum also ensures a controlled and clean environment.
Because it uses whole metal powder, this technique creates high-density products. It is used primarily in the automotive, medical, and aeronautics industries.
Digital Light Processing (DLP)
Digital Light Processing (DLP) works with photopolymers and is very similar to stereolithography. The main difference is the source of light. DLP technology uses a conventional light source such as an arc lamp and a liquid crystal panel. The photopolymer resin is then applied to the entire vat in one pass. This makes it more efficient than stereolithography. It produces 3D printed parts of high precision and excellent resolution, which are perfect for prototyping.
The Future of 3D Printing
3D printing is changing the face of manufacturing. It provides quick and inexpensive solutions for prototyping and manufacturing. It has revolutionized manufacturing, where previously specializations and tools were required for industrial success. 3D printing is quickly closing this gap. 3D printing business opportunities continue to expand across all industries. With 3D printing technology constantly improving, it’s not surprising that 3D printers could soon be commonplace in homes and offices.
What is 3D printing in simple words?
3D printing can be described as a method of creating solid three-dimensional objects. A 3D printer is used to build the object layer by layer. Printing 3D objects can be done with a variety of materials, including plastics, metals and ceramics.
What are the differences between 3D printing and traditional manufacturing?
Traditional manufacturing involves skilled labor and additional materials like molds for injection molding and tooling to create specialized objects. To create an eco-friendly 3D object, 3D printing requires only CAD software, a computer, a printer, and material.
What is the main use of 3D printing?
Businesses have many options for 3D printing to make prototyping easier. They can also create complex designs and high-quality products using 3D printing.
