Before we look at how photocentric are addressing the manufacturing gap,
00:06
let's take a brief look at the status quo of the core technology they are using.
00:11
LCD 3D printing is an advanced additive manufacturing process
00:15
that uses an LCD screen to create high
00:18
resolution patterns over a pool of liquid resin.
00:22
The process works by shining light through the pattern on the LCD screen,
00:27
curing the resin layer by layer to build a 3D object.
00:31
Each layer is precisely formed as the screen blocks
00:35
or allows light to pass through specific areas,
00:38
controlling the solidification of the resin.
00:41
This method offers high accuracy and detailed results,
00:45
making it ideal for applications requiring fine features and intricate designs.
00:51
The printed component is then washed to remove
00:54
any excess liquid resin on the surface.
00:57
This is typically a manual process carried out
00:60
after removing the components from the printer.
01:03
Finally,
01:03
the components are manually moved to a chamber to
01:06
be cured by exposing them to UV light.
01:10
The key benefits of LCD printing stem from its speed,
01:14
accuracy and simplicity.
01:16
First,
01:17
the process completes each layer quickly by displaying a single image.
01:22
This means that the time to complete each layer is
01:25
independent of the size of the area to be printed.
01:28
Second,
01:29
it provides high dimensional accuracy,
01:31
ensuring that parts are produced with precise
01:34
detail and minimum variation between prints.
01:38
Because there are fewer moving parts in the printing process,
01:41
LCD printing is more reliable and easier to maintain,
01:45
reducing the risk of mechanical failure and lowering operational costs.
01:51
This combination of speed,
01:52
precision and simplicity makes LCD printing an excellent
01:56
choice for both prototyping and small scale production.
02:02
In LCD 3D printing,
02:04
the digital thread connects the process from 3D CAD design to the printer,
02:09
where the object is built layer by layer.
02:12
This thread remains connected throughout the design and printing phases.
02:18
The digital thread breaks in the LCD
02:24
A bottleneck arises from manual steps like washing and curing,
02:28
which aren't fully integrated into the digital workflow.
02:32
These tasks require human intervention and slow down production.
02:36
This disconnected thread creates inefficiencies,
02:40
particularly for high volume printing.
02:43
Photocentric is addressing this by working to
02:45
integrate post-processing into the digital thread,
02:48
aiming for a fully automated workflow that
02:50
eliminates delays and improves overall production speed.
02:55
Instead of the workflow being carried out in a linear fashion,
02:58
automation could allow tasks such as washing and
03:01
curing to be carried out in parallel,
03:04
avoiding a bottleneck.
03:06
There is also a need to balance the number of printing,
03:09
washing and curing processes,
03:11
and this can change depending on the components being produced at scale.
03:16
As 3D printing scales toward mass production,
03:19
several barriers arise.
03:22
Factory configurations must adapt to varying print sizes,
03:26
materials and geometries,
03:28
slowing production.
03:30
Breaks in the digital thread during post-processing make
03:33
it difficult to track and plan production efficiently.
03:36
Additionally,
03:37
manual post-processing bottlenecks like washing and curing
03:41
limit throughput,
03:43
especially as production volumes increase.
03:46
Finally,
03:47
custom jobs require frequent adjustments to the production line,
03:50
adding complexity to scaling operations.
03:54
Overcoming these challenges is crucial for
03:56
photocentric's move into large scale manufacturing.
