Methods & Technologies

3D printing or additive manufacturing 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.

Has been around since the early 80’s modern 3D Printing by:
Charles W .Hull , stereolithography technique.

Methods and technologies of 3D Printing:

SLA (Stereolithography):
the laser beam traces a cross-section of the part pattern on the surface of the
liquid resin. Exposure to the ultraviolet laser light cures and solidifies the pattern
traced on the resin and joins it to the layer below.

SLS(Selective laser sintering):
The laser selectively fuses the powdered material by scanning the cross-sections
(or layers) generated by the 3D modeling program on the surface of a powder bed.

FDM (Fused deposition modeling):
The FDM technology works using a plastic filament or metal wire which is unwound
from a coil and supplies material to an extrusion nozzle .The nozzle is heated to melt
the material by a numerically controlled mechanism. The object is produced by
extruding melted material to form layers as the material hardens immediately after
extrusion from the nozzle.

LOM(Laminated object manufacturing):
after the first layer of a sheet material is loaded onto a stage, a laser or razor traces the
designed cross-section to define the pattern on the layer. After the excess material of the
sheet is removed, a second layer covers the previous layer and the laser or knife tracing will
define the next pattern based on information in the .STL file. Adjacent layers are combined
by use of adhesives or welding for paper or metal, respectively. These steps are repeated to
generate a layered 3D model.

Printing Biosensors and electrodes for electrochemical reaction
Printing chromatography columns
Printing flow – cells
Printing mili fluidic devices and micro fluidic devices

The interconnect, a flexible polymer gasket co-printed with, rigid clamps, elim-inates
adhesives and additional assembly by direct multi-material 3D, printing from a computer-
aideddesign model.

Experimental setup used to conduct
long-term reliability testing.

Interconnects delivering three different fluids, via adhesive-free connections, into separate
channels have also been demonstrated.

The three bed geometric designs: 1- simple cubic beads, 2- straight channels, 3- herringbone channels

where Ѳ is the dimensionless time defined in terms of the theoret-ical
residence time, estimated from the designed geometry of the
lattice structure.

The SC coloumn is better than the other due to have a Ѳ close to one.

Low cost lab-on-a- chip prototyping with a consumer grade 3D printer:
In this work, affordable 3D printed LOC devices have been demonstrated. Complex geometries,
directly created in 3D printed structures, enable transference of demanding fabrication tasks to the
printer, thus maximizing reliability and removing the influence of user fabrication skills from the
prototypes.

For H2O2 detection with ULOC, connectors were assembled with silicon tubing:
C) control solution
S) 0.1μM (sample)
H)1μM (high level)

ADVANTAGES

 Process is slow
 Components do not have enough strength.
Cost of raw materials
 3-D printers are still expensive.
 Misuse of technology
 Although 3-D printers have the potential of creating many jobs
and opportunities, they might also put certain jobs at risk .
DISADVANTAGES

3D printing is rapidly maturing
Still a lot to discover
Can save lives (literally)
May disrupt property and manufacturing processes
Ethical and law questions need to be solved
Potentially very dangerous
