Types of 3D printers



3D printing is an innovative technology that lets you create a physical object from a digital model. It started in the '80s under the name ‘rapid prototyping’ because this was the purpose of the technology: to prototype faster and cheaper.



The reasons there are different types of 3D printers and printing processes are similar to that of the 2D printers we’re so familiar with. It all comes down to the following six considerations:
  • Printer cost
  • Print quality
  • Print speed
  • Printer capability
  • Practicality
  • User expectations
Some printers only print text others text and graphics. The technologies and materials used also vary, and the way the machine extrudes ink to paper. 3D printers are even smarter. And like their 2D counterparts, they also offer a range of options including quality, materials, and price.

There are various 3D printing methods which were developed to build 3D structures and objects. A number of them are prevalent nowadays, and a few have fallen by the wayside.

The seven different types of 3D printers

  • Fused deposition modeling (FDM)
  • Stereolithography(SLA)
  • Digital Light Processing(DLP)
  • Selective Laser Sintering (SLS)
  • Selective laser melting (SLM)
  • Laminated object manufacturing (LOM)
  • Digital Beam Melting (DBM)

3D Printing in Education

3D Printing is an aspiration for many educational institutions.  Currently, 3D printing technology is becoming one of the new key technologies. It enables companies to cut costs, shorten their time-to-market, helps them to produce stronger and lighter parts and improve their efficiency. For that reason, it is important that students understand the technology of the future global economy. In the US and other places, already summer camps have been set up to teach 3D printing techniques over the summer. Children from a young age get to explore the subject of additive manufacturing. 3D printing  works by starting with a digital model in a 3D CAD (Computer-Aided Design) file and then creating a physical three-dimensional object. An object is scanned - or an existing scan of an object is used, which is processed by a piece of software known as a “slicer.” The slicer converts the model into a series of thin, 2-dimensional layers and produces a file with instructions (G-code)...

Selective Laser Sintering (SLS)

Many Powder Bed Fusion devices also employ a mechanism for applying and smoothing powder simultaneous to an object being fabricated, so that the final item is encased and supported in unused powder. Types of 3D Printing Technology:  Selective Laser Sintering (SLS) Materials:  Thermoplastic powder (Nylon 6, Nylon 11, Nylon 12) Dimensional Accuracy:  ±0.3% (lower limit ±0.3 mm) Common Applications:  Functional parts; Complex ducting (hollow designs); Low run part production Strengths:  Functional parts, good mechanical properties; Complex geometries Weaknesses:  Longer lead times; Higher cost than FFF for functional applications Creating an object with Powder Bed Fusion technology and polymer powder is generally known as Selective Laser Sintering (SLS).  Next, a recoating blade or wiper deposits a very thin layer of the powdered material  typically 0.1 mm thick onto a build platform. A CO2 laser beam then begins to scan the surface...

Selective laser melting (SLM)

Selective Laser Melting   (SLM) allows the manufacture of functional components with high structural integrity at a low cost and is compatible with various materials, including biocompatible titanium alloys.  Selective laser melting uses a laser to melt successive layers of metallic powder. The laser will heat particles in specified places on a bed of metallic powder until completely melted. The CAD 3D file dictates where melting will occur. Then, the machine will successively add another bed of powder above the melted layer, until the object is completely finished. SLM is a powder bed AM technology in which parts are fabricated layer by layer using the action of a high-energy beam on a powder bed. In this process, the powders are fully melted and solidified. The process is very similar to the SLS process but the energy of the beam is much higher and the process is performed under a controlled atmosphere. SLM is currently very popular for the fabrication of metallic ...
