Following this, the actual 3D modelling procedure begins. The artists utilise
specialised software to create three-dimensional drawings of the objects,
intending to animate them in a subsequent phase.

Texturing involves the incorporation of a two-dimensional image into either the
model’s background or the model itself, which was generated in a preceding
phase.

Afterwards, light and shadow must be balanced to create objects that are as

realistic as possible. This stage is called shading.
Animation and rigging involve providing the intended motion of the model and
adjusting if needed. The process of adding a moveable skeleton to a model is
known as rigging, as an animated model cannot exist without one.

The final step in the 3D modelling process is the incorporation of music and after-
effects to produce an even more vibrant animation.
3D printing is a method by which a three-dimensional, solid, tangible model is
created from a digital file, typically by depositing numerous thin, consecutive
layers of material. This rapid rise in popularity is because it enables manufacturing
to be accessible to a large number of individuals. This is related to the printers'

small size and relatively small price.

Early manufacturing techniques are frequently denoted as ‘’traditional
manufacturing’’ because additive manufacturing was not brought into existence
until the 1980s. In order to understand the fundamental distinctions between
additive and traditional manufacturing, it is necessary to classify all techniques

into three categories: subtractive, formative, and additive manufacturing.
3D objects are constructed using additive manufacturing, which involves the
deposition and fusion of 2D layers of material. This technique requires almost no
initial investment or time, which makes it ideal for prototyping. Rapid production

and disposal of used components are possible. An additional asset of 3D printing
is the capacity to produce components with virtually any geometry.
Objects are produced by subtractive manufacturing processes, such as turning
and milling, which involve the removal of material from a solid block, commonly
known as ‘’blank.’’ Its applicability is nearly universal, as virtually any material may
be machined. Exceptionally precise and highly repeatable components can be

manufactured using this technique due to the extensive control over each process
step. It is the most cost-effective method of production for the vast majority of
designs, despite the fact that it increases preparation time and expenses due to
the need for Computer Aided Manufacturing (CAM) to plan customised tool

trajectories and efficient material removal.
