*:･ﾟ3D printing and my first design ✧*:･ﾟ

Finally we are in the best part of this module, 3D Printing ! Can't wait to print my first ever product! ❣

What is 3D printing and the different types?

✧⋄⋆⋅⋆⋄✧⋄⋆⋅⋆⋄✧✧⋄⋆⋅⋆⋄✧⋄⋆⋅⋆⋄✧✧⋄⋆⋅⋆⋄✧⋄

3D printing or additive manufacturing is process of making three dimensional object from a digital file through a process called digital fabrication.

The object is created from successive layer of material which is composed with a lot of thin lines. In every section of the printed object, these layers can be observed if you see closely and depending on the thickness of the lines.

From what I learnt during ICPD class, digital fabrication is a design and manufacturing workflow where digital data directly drives manufacturing equipment to form various part geometries.

This data most often comes from CAD (computer-aided design), which is then transferred to CAM (computer-aided manufacturing) software.

The output of CAM software is data that directs a specific and subtractive manufacturing milling machine.

There are many types of 3D printing, the Fused Deposition Modeling (FDM) and the Stereolithography (SLA) are most commonly available due to their relatively lower cost.

The one that I will be using in school is the FDM. Hence, I will focus more on FDM for the introduction :)

What is FDM? ✎

Fused deposition modeling is an additive manufacturing technology that creates 3D components using a continuous thermoplastic or composite material thread in filament form.

The working principle is when the extruder feeds the plastic filament through an extruding nozzle, which is melted and then selectively deposited layer by layer onto the build platform in a predetermined automated path create a physical model of the object.

Pictures on the left side of this section showed the component in a FDM printers and a closed up image at the nozzle part.

First design in Fusion: Magnetic pilot marker holder !

For this module, I use Fusion 360 to create the sketch of my design. I was randomly assigned to create a magnetic pilot marker holder. The dimensions of the magnet given are 30mm (L) x 20mm (W) x 3mm (D).

The main concern when i was designing is the placement orientation of the marker. If you use marker before the worst thing that you ever want to happen is when the ink overflow. The ink is so hard to wash off and we don't to make the place messy. So, putting the cap facing downwards is a absolutely 'NO'. Next, how about putting the cap facing upwards? It will cause the tip to dry off and it need some time to absorb the ink again during our next usage. As a conclusion, the best way to orientate the marker is to put it sideways.

The easiest way to design this marker holder, is to have a rectangular box that can fit the marker and stick on the whiteboard.
