What is 3D Printing?
3D printing is a 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 entire
object is created.
Each of these layers can be seen as a
thinly sliced horizontal cross-section
of the eventual object.
According to Schaffhauser(2013):
3Dprinting is relevant in teaching
and learning as a way to enable
"more authentic exploration of
objects that may not be readily
available" to teachers and students; it
provides a means to let students
handle "fragile objects," such as
fossils and artifacts that can be fairly
quickly prototyped and printed out;
and it opens up "new possibilities for
How does 3D Printing work?
The website 3d printing .com describe how 3D printing work :
It all starts with making a virtual design of the object you want
to create. This virtual design is made in a CAD (Computer
Aided Design) file using a 3D modelling program (for the
creation of a totally new object) or with the use of a 3D scanner
(to copy an existing object).
A 3D scanner makes a 3D digital copy of an object. 3d
scanners use different technologies to generate a 3d model such
as time-of-flight, structured / modulated light, volumetric
scanning and many more.
Applications of 3D printing:
The web site of 3D printing state that
the general Applications of 3D printing
include rapid prototyping, architectural
scale models & maquettes, healthcare
(3d printed prosthetics and printing
with human tissue) and entertainment
(e.g. film props).
Other examples of 3D printing would
include reconstructing fossils in
paleontology, replicating ancient
artifacts in archaeology, reconstructing
bones and body parts in forensic
pathology and reconstructing heavily
damaged evidence acquired from crime
Usage 3D Printing in Classroom:
According to Martha Slack (2014) 3D printing will revolutionize
learning because it lends itself to low-risk, low-cost innovation.
Since ideas can materialize within minutes, students can see their
work as tangible products. When students have access to 3D
printing, abstract concepts in science and mathematics have the
potential to be transformed into concrete (plastic) visuals.
• Sue Poremba (2015) in her article “ Finding purpose for 3D
printers in schools” she state ways that 3D printing offers to
help student in class: “3 D printing offers multiple ways for
students to get hands-on experience and to gain marketable
skills before leaving high school.
3D Printing enable student to
explore and try new things,
and enable them to remove
fear, instead it embodies them
with confidence to venture into
the unknown. Educators and
students a like an exploring the
different ways that 3D printers
can influence and enhance the
learning in the classroom.
