3D Printer
3D printing
is a process of making a three-dimensional physical object from a digital file
designed by various CAD software. It is fast and economical technique. 3D
printing is emerging as an energy efficient technology and is being utilized in
every field like medical, industry, education, construction, for making
personalized jewellery, apparel, etc. In our lab we have Hyrel 3D printer of
model “System 30M”. This model has four tool positions for mounting four print
heads. Four different types of heads can be mounted on tool position and
printing can be done simultaneously with all heads. We have three different
types of print heads in our lab.
1. Filament
based head:
·
We have MK1
250 model in which temperature can go up to 250°C.
·
Filament
can be printed directly through nozzles of different diameters.
·
It provides
excellent print quality and easy to use.
·
It extrudes
1.75 mm filament and filament can be changed very easily.
·
Compatible
with the materials ABS, HIPS, Nylon, PET, PLA, PP.
2. Reservoir
heads
It is used
to print non filament-based materials like fluid or emulsions at or above room
temperature with or without crosslinking.
a. Plastic
Reservoir Head:
· We have SDS 60 model (cold flow head) in which 60
cc of fluid or emulsion can be filled and print directly at room temperature.
· It is compatible with Liquids, Gels, Pastes,
Biologicals, Resins and other low viscosity emulsifiables.
· Instantly ready to 3D print because no heat up
time required
· Allows use of sterile syringes and luer needles.
· UV LEDs are also available with the head for
crosslinking
b. Metal
Reservoir Head:
·
We have KR2
15 model (warm flow head) which can withstand with service temperature up to
150°C.
·
It can be
used without heat.
·
It is
compatible with the materials such as Waxes, Glues, Hot Glues, Polymer Clays or
any custom formulations.
·
UV
crosslinking is also possible by using UV LEDs which can be attached with this
head.
