Additive Manufacturing VS 3D Printing

Some use the terms additive manufacturing and 3D Printing interchangeably. However, there is a distinct difference between the two methods. For example, additive manufacturing (AM) is an umbrella term to describe the various technologies and processes used for product creation. It involves fabricating items by adding materials one layer at a time.

We offer fast, high-quality, tailored PROTOTYPING solutions for leading companies in a wide range of industries.

Meanwhile, 3D printing service is a type of AM. With binder jetting, material extrusion, and powder bed fusion, additive manufacturing encompasses multiple methodologies. The 3D printing subset uses computer-aided engineering to create three-dimensional objects from digital files. It is one of the most commonly used AM processes outside traditional manufacturing.

Understanding 3D Printing Service

Advanced manufacturing facilities offering a 3D printing service will likely use computer-aided design (CAD) software to create objects using a digital mockup. In 3D Printing, engineers use materials such as thermoplastics or photopolymer resins to build structures layer by layer. The required 3D printing filament depends on project parameters.

Imagine a traditional printer that prints images on a two-dimensional plane by drawing lines across the paper. It follows a set of instructions programmed on a computer to develop unique images or text based on different criteria. A 3D printing service is similar, except it prints three-dimensional objects.

This bottom-up manufacturing technique is one of many additive manufacturing processes. It allows teams to produce or enhance complex shapes and geometries that are otherwise difficult or impossible to create. The standard 3D printing service often looks like this:

Step One: Development, Design, and Dissemination

The first step in 3D printing services involves engineers and product developers collaborating on different concepts. Many teams utilize rapid prototyping for fast and efficient design iteration before the next steps.

Processing begins with the creation of a three-dimensional model using CAD. Some teams also scan existing objects into the system using a 3D scanner.

Step Two: Slicing and Pricing

The second step in the 3D printing service consists of slicing three-dimensional models into thin cross-sectional layers. Engineers use sophisticated software to develop these digital blueprint guides on each detail.

Slicing helps groups determine the appropriate materials for 3D printing projects. This essential phase teaches teams about design consistency, quality, manufacturability, and cost.

Step Three: Material Matters

In the third step, engineers choose the materials that best suit their product’s design and distribution plans. They must consider various other factors also, including:

  • Strength
  • Flexibility
  • Appearance
  • Environmental impact
  • Complexity

Additive manufacturing with 3D Printing sometimes means limiting the materials you can use. Many facilities can process plastics, metals, ceramics, biological materials, and food. Talk to an AM expert for more information.

Step Four: Printing and Post-Processing

Manufacturing teams can begin building objects after the rapid prototyping and design iteration steps. The printing processes vary depending on the required technology, materials, and timeline. However, fused deposition modelling (FDM) is the most common 3D printing service.

The post-processing steps follow with support structure removal, cleaning, sanding, and finishing. This phase is crucial because it aligns the final product’s appearance with the distributable standards.

3D Printing Service Advantages and Limitations

Manufacturers choose 3D printing services for multiple reasons. The technology is flexible and fast, offering quick turnovers and shorter lead times with less waste. Teams that use rapid prototyping with lean additive manufacturing techniques see tremendous benefits despite the applicable limitations.

Engineers prefer 3D Printing for customized designs. They can make unique objects and then reiterate them consistently. Many 3D printing services are more cost-effective because of the on-demand manufacturing capabilities and one-off production variables. Teams can tailor designs to individual needs or personalize aspects to suit evolving standards.

AM techniques like 3D Printing also reduce assembly requirements and time. Digital fabrication produces objects with intricate geometries and minimal errors, lowering expenditures. Manufacturers can choose advanced materials to help improve fidelity and ensure top quality for highly regulated industries.

Conversely, limited production speeds and size restrictions might concern some. Traditional manufacturing methods are often faster than digital fabrication techniques. Building objects layer by layer takes time, and the speeds can depend on several factors, such as:

  • Rapid prototyping results
  • Object dimensions
  • Design complexity
  • Preferred materials
  • Printing technologies
  • Surface finish
  • Industry standards

Most 3D printing service providers will demonstrate equipment and software constraints. Ask about maximum sizes allowances for different projects. Then discuss the materials to determine surface finishing parameters and other post-processing requirements.

Quality Control Concerns in 3D Printing

Despite the limitations, 3D printing services provide significant advantages for design flexibility, rapid prototyping, and quantifiable production. However, some teams might stumble during quality control. Ensuring consistency means closely monitoring multiple properties, so speak to an AM expert to develop a comprehensive plan.

The capabilities of 3D Printing, rapid prototyping, and additive manufacturing technologies are already expanding. As technology advances, facilities could utilize more sophisticated CAD software and programming for faster design iteration and improved stability.

Understanding Traditional Manufacturing

Traditional manufacturing methods can provide unique benefits unavailable with digital fabrication, 3D Printing, and AM. These established techniques produce high-quality goods at scale using subtractive processes. Engineers remove material from workpieces to create desired shapes using various textiles not always accessible with 3D printing services.

Manufacturing with traditional methods means higher production volumes and material diversity. However, conventional techniques can also mean longer lead times and higher costs for prototyping. Considering the options is critical to achieving your goals. Let’s look at a few of the available methods next.

Injection Molding

Use this method when producing plastic parts in high volumes. Experts will inject molten materials into a mold cavity, cool it until it solidifies, and process the final form.

CNC Machining

Choose computer numerical control when projects require lathes, mills, or drills. Operators will remove material from workpieces to produce high-precision metal or plastic components.

Casting

Use casting when producing complex shapes such as engine parts, jewelry, and sculptures. Experts can cast molten metals using identical molds for optimal consistency.

Extrusion

This traditional manufacturing process is suitable for creating a continuous profile with specific cross-sectional dimensions. Engineers force metal or plastic through a die when producing pipes, tubs, and sheets for various assemblies.

Joining

Select joining techniques like welding, brazing, and soldering. These methods best combine separate parts into a unified whole without decreasing product functionality.

Forming

Forming processes, such as bending, stamping, and forging, create different objects by applying force, heat, or pressure. Talk to your team about the pros and cons of each material.

Traditional manufacturing approaches must align with multi-level production goals and sustainable fabrication standards. Discuss the benefits and limitations of conventional methods vs. advanced techniques such as additive manufacturing and 3D Printing.
