As a
human race, it’s significant to preserve the buildings and structures that came before us to study
the past as well as to get the reflection on human life, beliefs, and
conditions about how they have transformed. This was the situation for Florence’s Baptistery Cathedral, where a
project started in 2016 for replacing and restoring the unique 14th-century
bronze doors on the southern side of the building. The challenge involved in
the project was the absence of molds &casts for the doors. While the east
& north doors had plaster casts, enabling the creation of duplicates, Pisano’s
south doors did not.
Restoration with 3D Laser
Scanning
·
Taking
into consideration the complex façades of the doors & artwork and the need
for recreating them perfectly, the restoration team used 3D laser scanning for the project, for creating accurate digital models to capture the detail down to one-hundredth
of a millimeter.
·
Compared
to outmoded casting approaches that heavily involve communication with the
doors, during the 3D
scanning process,
the only mechanism stirring the delicate artifacts were the photons.
·
After
careful investigation of competent firms capable of managing a project of enormous
cultural importance, a 3D
scanning/printing service provider was chosen. With expertise in digital
capture, 3D design, & 3D
production services, a profound level of significance is achieved. The
restorers continued their work on the doors and the unique decoration &superb
details of Pisano’s artistry started emerging.
·
Next,
the 3D scanning started for digitally
capturing the intricately crafted panels of the bronze doors. 3D scanner helps to
scan the crucial jobs demanding utmost precision and lifelike digital capture. It’s
comfortable to use a 3D scanner, as the results can get exhibited in real-time
on the laptop screen.
·
3D
Scanner facilitated in reversing engineering
practices as
a small object from a priceless cloisonné urn from the early Qing dynasty,
throughout the way to small-scale turbofan mechanisms for Rolls Royce Trent 500
engine, and innumerable objects in between.
·
From
the inception to the final stage, the 3D
scanning of the 3-year-long project was completed in just 10 days. During that
time, 28 of Pisano’s original panels
were digitally seized in high-resolution color &changed into breath-taking
3D models.
How Laser Scanning Brought
Life to Pisano’s Innovative Creation?
·
The
lightweight & handheld scanner enabled the technician to renovate
each panel
and capture it quickly and easily. The scanner’s clean scans, along with the speed
of capture, kept the file size and processing times to a minimum.
·
With
scanning, the scans were processed in the studio. The scanning technician post-processed
the scans in software, removing any unwanted data, supporting and registering
the scans, and exporting them as 3D models,
used for working closely with the intricate details of the panels and the complex
geometries.
·
The
3D
models
were sent for 3D printing as
positive panels on a 3D Systems Selective Laser Sintering printer. Once the
panels were prepared, they were sent to the Artistic Foundry for creating
negative silicone molds from the positive panels.
·
The
negative molds were utilized for final bronze casting replicas through the mislaid
wax cast. After the cooling of the cast, artists, and craftsmen went to work,
refining & polishing the practical details, feet, clothes & other
elements, bringing life to all the lines, shapes, and curves of Pisano’s innovative
creation.
·
After
the finishing, in the final process acids were poured across the surface of the
bronze panel for oxidizing the metal and bring about an authentic appearance to
the masterpiece. Once the panels were prepared, all elements of the doors were
assembled in a month, eventually accomplishing the final spectacular consequences.
·
Currently,
the doors have been re-established to their original site on the south of Florence’s Baptistery Cathedral, to be admired in curiosity
for generations.
So, laser scanning technology has been able
to completely meet the requirements of museums and historical societies to
rescue precious historical artifacts & monuments. Invaluable creations
are disappearing across the world. However, with 3D scanning, extraordinary inheritances can be numerically
captured and brought back to life. If humans can guard what they have learned
from the past, beautiful paths can be created with 3D laser Scanning to BIM technology for
moving into the future. To know more about point
