INTRODUCTIO
N
3D printing, also known as additive 
manufacturing, is a revolutionary process 
that creates physical objects directly from 
digital designs. By layering materials 
precisely, it allows for rapid prototyping, 
customization, and innovation across 
industries, transforming how products are 
developed, tested, and manufactured.

HISTORY AND EVOLUTION OF 3D 
P3DR pIrNinTtinIgN oGriginated in the 1980s with 
stereolithography. Over time, it evolved 
with advancements like FDM and SLS 
technologies. Once limited to industrial 
use, its affordability and accessibility 
have now expanded its presence into 
homes, schools, and startups, redefining 
design and manufacturing possibilities 
globally.

HOW 3D PRINTING 
02
WORKS
3D printing works by converting 
digital models into physical objects 
through a layer-by-layer material 
deposition process. A 3D printer reads 
the design file, slices it into layers, 
and extrudes or solidifies material 
accordingly. The process varies based 
on the printer type and the materials 
used.

TYPES OF 3D 
PRINTING 
TECHNOLOGIES
Common 3D printing methods include 
Fused Deposition Modeling (FDM), 
Stereolithography (SLA), and Selective 
Laser Sintering (SLS). Each technique 
differs in materials, precision, and 
applications. Choosing the right 
technology depends on the object’s 
complexity, resolution needs, strength 
EXPLORING 3D PRINTING TECHNOLOGY requirements, and pFrOoLdLOuWction scale.
MATERIALS USED IN 3D 
PRINTING
3D printers utilize various materials 
including plastics (PLA, ABS), metals 
(steel, titanium), ceramics, and even 
bio-materials. The choice depends on 
the application—plastic for prototypes, 
metals for industrial parts, and 
biocompatible materials for medical 
use. Material innovation continues to 
expand 3D printing capabilities.
