Understanding the Seven Types of Additive Manufacturing

Additive manufacturing technologies

• Direct Metal Laser Sintering (DMLS) Within DMLS, a laser sinters each layer of metal powder so that the metal particles adhere to one another.
• Direct Metal Laser Melting (DMLM) and Electron Beam Melting (EBM)
• Stereolithography (SLA)

The term additive manufacturing comes from the process of how objects are created in 3D printing. To simply answer the question “Why is it called additive manufacturing?”, it is because the build process adds instead of subtracts raw material.

• Binder jetting.
• Directed Energy Deposition.
• Powder Bed Fusion.
• Sheet Lamination.
• Material Extrusion.
• Material Jetting.
• Vat Photo Polymerization.

Here are solutions to the most common problems: layers failing to attach, stringing, and overheating. Sometimes there isn’t the time or money to call in the experts. The 3D printer has to be back up and running ASAP.

Stringing (otherwise known as oozing, whiskers, or “hairy” prints) occurs when small strings of plastic are left behind on a 3D printed model. This is typically due to plastic oozing out of the nozzle while the extruder is moving to a new location.

Using 3D Printing For Other Hobbies It’s like many hobbies, they can be a waste of time and money, or you can use it to the best of your abilities and make something out of it. Many 3D printers make sure to use it for things they planned to do, such as playing Dungeons and Dragons with friends and family.

Pros and Cons of 3D Printing

• Freedom of Design. 3D printing boasts the ability to produce complex geometry that machining and injection molding may struggle with or may simply not be able to make.
• Rapid Prototyping.
• Print on Demand.
• Lighter, Stronger Parts.
• Waste Reduction.
• Speed.
• Cost-Effective.
• Accessibility.

TL;DR : The main advantages of 3D printing are: reducing costs, less waste, reduce time, get an competitive advantage, reduce errors, confidentiality, production on demand.

Manufacturing applications

• Cloud-based additive manufacturing.
• Mass customization.
• Rapid manufacturing.
• Rapid prototyping.
• Research.
• Food.
• Agile tooling.
• Bio-printing.

Top Ten Advantages of Additive Manufacturing

• The Cost Of Entry Continues to Fall.
• You’ll Save on Material Waste and Energy.
• Prototyping Costs Much Less.
• Small Production Runs Often Prove Faster and Less Expensive.
• You Don’t Need as Much On-Hand Inventory.
• It’s Easier to Recreate and Optimize Legacy Parts.

The term “3D printing” is increasingly used as a synonym for additive manufacturing. For example, instead of milling a workpiece from a solid block, additive manufacturing builds the part up layer by layer from material supplied as a fine powder. Various metals, plastics and composite materials can be used.

Thus, the advantages of subtractive prototyping include a wide selection of end-use materials, good dimensional control and surface finish, and a high degree of repeatability suitable for end-use manufacture. The drawbacks are that there is some material waste, and geometry limitations.

Pros and Cons of Additive Manufacturing

• Complexity is free: It actually costs less to print a complex part instead of a simple cube of the same size.
• Variety is free: If a part needs to be changed, the change can simply be made on the original CAD file, and the new product can be printed right away.

The accuracy of 3DP was 0.67 ± 0.43% for the original model’s first measurement, 0.69 ± 0.44% for the original model’s second measurement, 0.38 ± 0.22% for the moderate model and 0.55 ± 0.37% for the worse model. The repeatability of the used measurement method was 0.12% for the PolyJet and 0.08% for the 3DP.

While additive manufacturing can save the aerospace industry time and money, it can also save lives in the medical field. With an expected growth of $2.88 billion from 2015 to 2023 according to SmarTech Markets, the medical industry can expect a future of nano-scale medicine and even complex printed organs.

5 Major Benefits of Additive Manufacturing You Should Consider

• Cost of Entry is Becoming More Affordable.
• It Is Easy to Change or Revise Versions of a Product.
• Training Programs Are Becoming Readily Available at All Levels.
• It Reduces Waste Production.
• It Saves on Energy Costs.
• Demand Continues to Rise.

7 Benefits of Manufacturing in the United States

• More Jobs for Americans. Choosing U.S.-based manufacturing means creating jobs here at home for Americans.
• Reduced Cost for Deliveries.
• Shorter Lead Times.
• Environmentally Friendly.
• A Higher Standard of Safety & Quality Control.
• Homegrown Customer Service.
• U.S. Manufacturers Pay U.S. Taxes.
• Learn More.

Additive manufacturing enables eco-friendly products, it provides for end-of-product-life-cycle solutions for eliminating waste and scrap and it allows for resource-efficient material choices via recycling. The benefits can even be realized all at once.

Manufacturing means producing goods in large quantities after processing from raw materials to more valuable products. Manufacturing helps transforming the raw materials into finished goods on a large scale and thus helps earning profit as finished goods are costlier than raw materials.

Made in America: Avoiding the Disadvantages of Manufacturing Overseas

• Poor Quality.
• Low Labor Content.
• High Transportation Costs.
• Extended Supply Chain.
• Lack of Control.
• Increased Time-to-Market.
• Loss of Intellectual Property.

These features enable effective management of manufacturing processes, including production planning, scheduling, and inventory control. Traceability. Among the manufacturing execution capabilities available, these are key features to look for:Materials Requirement Planning.

There are four types of industry. These are primary, secondary, tertiary and quaternary.

Manufacturing: Features

• Master Production Scheduling (MPS)
• Material Requirements Planning (MRP)
• Quoting.
• Order Configuration/Estimating.
• Purchasing.
• Supplier Managed Inventory.
• Multi-Level BOM’s.
• Lot/Serial/Batch Tracking.

Characteristics of modern large scale manufacturing

• The specialisation of skills or methods of production.
• Mechanisation.
• Technical Innovation.
• Stratification and Organisational Structure.
• Uneven Geographic Distribution.

Engineers in the manufacturing industry could work in areas such as design, production, supply chain or logistics. Manufacturing is the process of adding value to raw materials by turning them into products: electrical goods, vehicles, aircraft, food, beverages, medical supplies, pharmaceuticals, and so on.
