Know More About 3D Printer And 3D Printing

What is a 3D printer?

3D printing, or additive manufacturing, is the construction of a three-dimensional object from a CAD model or a digital 3D model.  The term “3D printing” can refer to a variety of processes in which material is deposited, joined, or solidified under computer control to create a three-dimensional object, with the material being added together (such as plastics, liquids, or powder grains being fused), typically layer by layer.

In the 1980s, 3D printing techniques were considered suitable only for the production of functional or aesthetic prototypes, and a more appropriate term for it at the time was rapid prototyping. As of 2019, the precision, repeatability, and material range of 3D printing have increased to the point that some 3D printing processes are considered viable as an industrial-production technology, whereby the term additive manufacturing can be used synonymously with 3D printing

One of the key advantages of 3D printing is the ability to produce very complex shapes or geometries that would be otherwise impossible to construct by hand, including hollow parts or parts with internal truss structures to reduce weight. Fused deposition modeling (FDM), which uses a continuous filament of a thermoplastic material, is the most common 3D printing process in use as of 2020.

SLOG3D V2.5 is our third IoT printer. SLOG3D is based on the ULTIMAKER, one of the most popular models in the RepRap community. With the latest version, we have evolved it to create a professional printer, while maintaining the spirit of the original. We have opted for a new design that enables us to achieve a larger printing volume, reaching (X) 210mm x (Y) 297mm x (Z) 220mm.

What is 3D Printing?

3D printing or additive manufacturing is the process of making three-dimensional solid objects from a digital file.

The creation of a 3D printed object is achieved using additive processes. In an additive process, an object is created by laying down successive layers of material until the object is created. Each of these layers can be seen as a thinly sliced cross-section of the object.

3D printing is the opposite of subtractive manufacturing which is cutting out / hollowing out a piece of metal or plastic with for instance a milling machine.
3D printing enables you to produce complex shapes using less material than traditional manufacturing methods.

How Does 3D Printing Work?

It all starts with a 3D model. You can opt to create one from the ground up or download it from a 3D library.

3D Software

There are many different software tools available. From industrial grade to open source. We’ve created an overview on our 3D software page.

We often recommend beginners to start with Tinkercad. Tinkercad is free and works in your browser, you don’t have to install it on your computer. Tinkercad offers beginner lessons and has a built-in feature to export your model as a printable file e.g.STL or.OBJ.

Now that you have a printable file, the next step is to prepare it for your 3D printer. This is called slicing.

Slicing: From printable file to 3D Printer

Slicing basically means slicing up a 3D model into hundreds or thousands of layers and is done with slicing software.

When your file is sliced, it’s ready for your 3D printer. Feeding the file to your printer can be done via USB, SD, or Wi-Fi. Your sliced file is now ready to be 3D printed layer by layer.

Here Are Some Examples Of 3D Printing

3D printing encompasses many forms of technologies and materials as 3D printing is being used in almost all industries you could think of. It’s important to see it as a cluster of diverse industries with a myriad of different applications.

A few examples:

  • – consumer products (eyewear, footwear, design, furniture)
  • – industrial products (manufacturing tools, prototypes, functional end-use parts)
  • – dental products
  • – prosthetics
  • – architectural scale models & maquettes
  • – reconstructing fossils
  • – replicating ancient artefacts
  • – reconstructing evidence in forensic pathology
  • – movie props
