What is 3D?
The term "3D" refers to a three-dimensional thing that we can sense. To create anything three-dimensional, material is combined or solidified via computer control, and is added layer by layer In the 1990s, the phrase "rapid prototyping" was more applicable since 3D printing technologies were thought to be only suited for the manufacture of functional or aesthetically pleasing prototypes.

The Reasons for Several Types of 3D Printer
The reasons behind the various types of 3D printers and printing processes are similar to
those of traditional
2D printers. All of it boils down to the following six factors:
Printer cost
Print speed
Print quality
Practicality
Printer capability
User expectations
Type of 3D printer
Stereolithography (SLA)
A moving laser beam that is computer-controlled and pre-programmed using CAM/CAD software is used in the 3D printing technique known as stereolithography.
Digital Light Processing (DLP)
For the quick production of photopolymer components, DLP is a 3D printing method is employed. The main distinction between it and SLA is that whereas SLA machines utilize a laser to trace a layer, a DLP machine employs a projected light source to simultaneously cure the entire layer.
Fused deposition Modeling (FDM)
A continuous thermoplastic or composite material thread in the form of filament is used in fused deposition modelling, an additive manufacturing technique, to produce 3D components. The plastic filament is fed through an extruding nozzle by an extruder, melts there, and then in a specified automated route, is selectively deposited layer by layer onto the construction platform.
Selective Laser Sintering (SLS)
SLS, or selective laser sintering, is an additive manufacturing process that employs a laser as the energy and heat source to sinter powdered material, autonomously targeting the laser at spots in space specified by a 3D model, and binding the material together to produce a solid structure.
Selective Laser Melting (SLM)
In a particular type of 3D printing called selective laser melting, metallic particles are completely melted and fused to create almost net-shaped components with nearly full densities.
Electronic Beam Melting (EBM)
A kind of additive manufacturing for metal components is electron beam melting. It is frequently categorised as a quick production technique. By using an EB in a high vacuum to melt metal powder layer by layer, the method creates components.
Binder Jetting (BJ)
One of seven processes for additive manufacturing uses "binder jetting," which involves the selective deposition of a binding liquid to unite powdered materials to create a three-dimensional item.
Material Jetting (MJ)
One of the seven types of additive manufacturing (AM) technologies is called material jetting. In this process, build and support materials are selectively jetted onto the build platform, where they are then cured by either heat or UV radiation to create 3D objects.
This week, we worked on 3D Scanning and Printing group assignment. This assignment is about documenting what we learned in this week regarding additive vs subtractive manufacturing, various 3D printing processes and materials, specifications of 3D printer that we have in our Fab lab. We have also documented how we used 3D printer for our group assignment, material and tools that we used, what precautions need to be taken while operating the 3D printer along with the software required for generating G code for the machine. As a conclusion we characterized the design rules for our in-house 3D printer.
Objectives of the Group Assignment:
Understand additive manufacturing processes, their types, materials and tools
Understand how to operate the 3D printer
Learn safety precautions while operating this Machine
Test the design rules for our in-house 3D printer
3D Printing
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 material being added together (such as plastics, liquids or powder grains being fused together), 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.

Fracktory Software Side:-
The slicer, also known as slicing software, is computer software that converts a 3D object
model into specific instructions for the printer in the majority of 3D printing procedures.
In fused filament fabrication and other comparable processes, in particular, the conversion
from a model in STL format to printer commands in g-code format.
PLA (polylactic acid) is a thermoplastic monomer made from renewable, organic
sources like corn starch or sugar cane. PLA differs from conventional plastics
in that it is made from biomass rather than fossil fuels through the distillation
and polymerization of petroleum.
Step1:3D Printing display Homepage
The X- and Y-axes are commonly used for lateral movement in 3D printers, while
the Z-axis is used for vertical movement. Each layer is deposited using a combination
of the X and Y movements, with the Z movement responsible for advancing layers to a
pre-determined height in the 3D slicer.

If you're new to 3D printing, a nozzle temperature of around 210°C,
a heated bed temperature of approximately 60°C, and a printing speed
of 60 mm/s are a decent place to start.
The machine must be calibrated in order for the bed to be absolutely flat
in relation to the nozzle head. The machine table must be properly parallel
and calibrated in order for the printed job's quality, surface finish, and
uniform printing to be achieved. There are two types of calibration: fast
(3 point resting) and full calibration (3 points plus 9 points resting).

what is the Subtractive Manufacturing method?
The design that I have to make is a design that cannot be made by any other 2-axis machine,
hence it is called the subtractive manufacturing method.

Remove Useless material-Using cutters, we must remove the material that was employed as a
support solely
for the purpose of printing but is not required in the final result.
