Week 12
Reflection:
We have recently received our 3D printed name tags that were designed during a previous lesson. When asked about the quality of the name tag, we have observed that the name tag was slightly fragile and seemed like it could break easily if forced is being applied on it. This is because the name tags had to all be printed under a short time hence decreasing the printing time which also decreases the product's quality. In week 12's lesson, we have learnt that there are many factors that contribute to the 3D printed product's quality. Factors such as nozzle temperature, infill density, thickness, layered height and many more affects its quality. Our group has been assigned to research and present about Additive Manufacturing and 3D Printing Technology.
Additive Manufacturing
Additive Manufacturing refers to a term that comprises of many different technologies. Such technologies consist of 3D Printing, Rapid Prototyping and Direct Digital Manufacturing. Additive Manufacturing is used to create products or 3D models. It can be done by using software applications such as Fusion 360 to design the desired product and then using another application such as the Slicer Cura to help print the model that was desgined from the device.
Advantages of AM
Additive Manufacturing can be applied into our daily lives as it is versatile which can be very useful. The reason behind its versatility is because the 3D printed objects are highly customisable. With this, companies could 3D print their own specific needed parts as quickly as possible instead of buying from a supplier which is definitely more cost and economically friendly and less time consuming. 3D printing could also be applied in food where people who are only able to eat soft food can now enjoy 3D printed soft food in another form that will make it look much more appealing and appetizing instead of consuming mush looking food. With this, they can enjoy their meals as per normal while being able to consume their needed nutrients. Additive manufacturing is so versatile that it can fulfill many needs ranging from creating machinery parts to even human body parts.
3D Printing Technology
3D printing technology comprises of Fused Deposition Modelling (FDM), Stereolithography (SLA) and Selective Laser Sintering (SLS) have their own strengths and limitations. In FDM, it uses liquid thermoplastics that solidify. One of its strengths is that it is a quick process which usually takes less than a day (24 hours) to complete. However, it is unable to produce products at a fine resolution. For SLA which uses laser technology to cure photopolymer mesh layer by layer, it is known to create products with high tensile strength. Its downside is that a specialised material might be needed to support certain designs of the models. Lastly for SLS that uses a high powered laser to fuse small particles together creates models with a supported build which makes the process easier as no support material is needed. However, in order to operate this, you have to be a highly skilled operator and it is not cost efficient to maintain and purchase the expensive machinery.
All in all, we have learnt a plethora of information regarding 3D printing such as the factors that contribute to quality, its never ending applications, its different methods and the different ways the material is being printed depending on its complexity of its design.
