3D printing is an excellent process for making prototypes and real-life products and has formed the basic call-up methods for efficiency and efficacy in production. And 3D printing is positively impacting the world that has been tending towards using rapid prototyping processes in mass production.

Therefore, it is important to know about applying 3D printing mass production, its advantages, and its various applications. This article will introduce everything you need to know about mass production using 3D printing.

The Advantages of Using 3D Printing for Mass Production

3D printing is a great technique used in mass production which comes to knowing the advantages of the method. Below are the reasons that make 3D printing a better choice.

· Faster Time to Market by Rapid Tooling

The manufacturing world is highly competitive, and the time taken to reach the market can be a huge deciding factor in the success of a business. This means that the chosen manufacturing process must be able to deliver a large number of products within a short period of time. An increase in production time and delivery will improve the availability of the business’s product in the market and give them an edge competition-wise.

Among the manufacturing process used in rapid prototyping, 3D printing is able to produce the necessary prototypes to check for flaws and deliver in terms of the real product. 3D printing mass production is not only in making products itself but also in making entities that can help in other manufacturing processes. For example, manufacturers can use the process to make 3D printed injection molds, which helps mass production injection molding.

· Flexibility to Quickly Change What You Are Making

In production 3D printing, manufacturers can easily change whatever they are making when there is an error or a need for a change. This trait is important in 3D printing batch production as it allows manufacturers to make prototypes by which they can check for flaws, analyze the functions of the parts, and do other things depending on the type of prototype they are working with. Consequently, it is easy for the designer to change things when they detect an error.

· The Ability to Customize Products

Performance and aesthetics are basic requirements of any growing business. Performance is in terms of product quality, while aesthetics is to attract customers. Both performance and aesthetics depend on the customization of products. Out of the different rapid prototyping processes used recently, production 3D printing is the most suitable for customization.

Depending on orders, you can delay or increase production. You can also demand a shift in 3D printing production parts’ design if there is a demand for a new type of product. Different types of materials available for 3D printing also make customization very easy.

3D Printing Materials For Mass Production Parts

There are three categories of materials in 3D printing. Each category comprises different materials with unique features and properties suitable for different products. Below are the common materials you could use.

Plastic Polymers

Plastics are the most common materials used in volume 3D printing. With it, it is possible to make products such as 3D-printed toys, household fixtures, desk utensils, vases, etc. Plastic materials’ popularity is due to features such as firmness, flexibility, smoothness, and color option, further improving their use in 3D production parts. We have a list of the common types of plastic polymers you can use.

· Polylactic Acid (PLA)

Polylactic acid/PLA is an eco-friendly plastic made from natural products and known for its biodegradability. It occurs in two forms: soft and hard, which shows their strength. Hard PLA is the more common type in mass production due to its hardness, strength, and durability.

· Acrylonitrile Butadiene Styrene (ABS)

ABS material or LEGO plastic is a plastic polymer known for its strength, firmness, and flexibility. ABS has many colors making it a common production 3D printing material for making tickers and toys, jewelry, and vases.

· Polycarbonate (PC)

Polycarbonate/PC is a suitable plastic polymer for 3D printers with nozzle design at high temperatures. It is common in mass production as a result of its high strength, toughness, insulation properties, and heat and impact resistance. The material is suitable for making electrical and telecommunication products.

· Polyamide (Nylon)

Polyamide or Nylon is a popular volume 3D printing material because of its strength, flexibility, and how it allows a high level of detail in printed products. The material is commonly used for printing products such as fasteners, toy cars, and figures.

Resins

Resins are less common 3D printing materials due to their limited flexibility and strength. They reach their end state when exposed to UV light and have different color options. Below are the three categories of resin materials you could use:

· High Detail Resin

This type of resin has a smooth surface and provides intricate details on small models. They are the perfect materials for testing designs.

· Paintable Resin

These types of resin have aesthetic appeals making them suitable for making products with rendered facial details.

· Transparent Resin

It is the strongest of the three and suitable for many products. It is suitable for models that must have a smooth surface and transparent appearance.

Metals

These are the second most popular 3D Printing materials. They are used through direct metal laser sintering (DMLS) or Selective Laser Melting (SLM). In 3D printing, metals are used in dust form. The dust is first heated to hardness in order to avoid casting. Consequently, it is possible to make direct use of the dust. Surface finishing process can then be undergone. Metals are common 3D Printing mass production materials due to their strength and durability, and common ones include:

• Stainless steel: For a product that comes in contact with water.
• Bronze: For vases and other fixtures.
• Gold: 3D printed rings, bracelets, and other forms of jewelry
• Nickel: Coins.
• Aluminum: For thin 3D printed metals

Additive Manufacturing Processes for Mass Production

Additive manufacturing is the industrial production name for 3D printing, which allows the creation of an object of varying complexity by making layers of the materials. In contrast to traditional manufacturing, they are efficient, effective, and reliable. Below are some additive manufacturing processes:

· Binder Jetting

Binder Jetting process uses a powdered material and a binder that acts as an adhesive to deposit a liquid binding agent onto powder particles, layer by layer. The additive manufacturing process has many industrial applications, such as aerospace parts, medical devices, automotive components, and more.

· Direct Energy Deposition

Direct energy deposition is compatible with many materials such as ceramics, metals, and polymers. The process involves melting materials and fusing them as it deposits. The mechanism is more common in repairing and rebuilding.

· Material Extrusion

It is a common additive manufacturing process by which a heated nozzle extrudes the necessary materials. The bed moves vertically while the nozzle moves horizontally. Bonding agents or temperature control mechanisms can adhere to the layers formed to each other.

· Powder Bed Fusion (PBF)

This is a metal additive manufacturing process. It takes advantage of either laser, heat or electron beam to melt or fuse powder materials together to form a solid three-dimensional part.

· Sheet Lamination

It comprises two methods. On the one hand, Laminated object manufacturing (LOM) is suitable for making products with alternate paper and adhesive having visual appeals. On the other hand, ultrasonic additive manufacturing (UAM) can join metals such as aluminum, stainless steel, and titanium using ultrasonic welding.

· Vat Polymerization

It involves using a vat of liquid resin photopolymer to create an object layer by layer. Mirrors are then used to cure successive layers of resin through photopolymerization.

· Wire Arc Additive Manufacturing

This additive manufacturing process builds products using arc welding power sources and manipulators. The process is formally known as arc deposition, and it majorly uses wire as a material source.
