3. INTRODUCTION
• 3D printing or additive manufacturing, creates
physical objects from a geometrical representation by
successive addition of materials.
3D printing technology can print an object layer by
layer deposition of material directly from a computer
aided design (CAD) model.

Nozzle-based deposition systems or Material extrusion: consist
on the mixing of drugs and polymers and other solid elements
prior to 3D printing. The mixture is passed through a nozzle that
definitely originates, layer by layer, the three-dimensional product.
And fused deposition modeling The melted material is deposited
layer-by-layer and fused together because the layers are in the
molten state as the build platform moves downwards until the
finished product is obtained.

Stereo lithography is an additive manufacturing process using a vat
of liquid UV- curable photopolymer ”resin” and a UV laser to
build parts a layer at a time.

CHALLENGESIN3DPRINTINGTECHNOLOGY
The technology is still under the developing stage. Hence it
undergoes several challenges such as optimization process,
improving performance of device for versatile use, selections of
appropriate excipients, post treatment method, etc.
To improve the performance of 3D printed products and to
expand the application range in novel drug delivery systems.
To achieve quality 3D Products, many important parameters
need to be optimized like printing rate, interval time between two
printing layer, distance between the nozzles and the powder layer,
etc.

FUTURE PROSPECTS
New opportunities In near future 3D printing approach will be
utilized in many ways such as –
Fabricate and engineer various novel dosage forms,
Achieve optimized drug release profiles,
Develop new excipients, avoid incompatibilities between
multiple drugs,
Drug dosage forms, supporting delivery,
Limit degradation of biological molecules or helping to
research cures.
