the idea of 3d printing our buildings is
[9]
nothing new
[10]
[Music]
[12]
faced with a desperate need to construct
[14]
more homes faster and in a more
[16]
efficient way countless innovators have
[19]
found themselves drawn by the idea of
[20]
being able to quickly print a structure
[22]
and have spent years trying to scale the
[24]
technology
[27]
but for all their efforts that 3d
[29]
printed world has proven elusive and
[31]
many impressive prototypes have
[33]
struggled to become viable for mass
[34]
production
[37]
but things have just taken a massive
[39]
step forward in germany with the
[40]
completion of the first ever 3d printed
[43]
home to become fully certified under a
[45]
national government's building
[46]
regulations
[47]
[Music]
[49]
the impact of this moment for
[50]
construction and for the buildings we
[52]
all use could be huge
[61]
with the promise of cutting waste
[63]
reducing time on site and addressing
[65]
labor shortages some see 3d printing as
[67]
the answer to many of our world's
[69]
challenges
[71]
originally used for small-scale
[72]
prototypes advances in 3d printing have
[74]
led to the creation of full-scale
[76]
structures like bridges and homes and
[79]
even plans for mankind's first martian
[81]
base
[82]
but while 3d printed structures have
[84]
appeared around the world from canada
[86]
and the netherlands to dubai which wants
[88]
to 3d print a quarter of its new
[90]
buildings by 2030 the technology is yet
[92]
to take off as a widespread building
[94]
technique
[97]
but the completion of this 3d printed
[99]
house in beckham germany is set to
[101]
change everything
[102]
developed by leading formwork and
[104]
scaffolding firm perry experts in its
[106]
disruptive products and technologies
[108]
departments and its project partners the
[110]
structure a detached single family
[112]
property is the first 3d printed house
[114]
in germany and offers 160 square meters
[118]
of living space across its two stories
[121]
critically the structure is the first 3d
[124]
printed building in germany to become
[125]
certified with a national building
[127]
accreditation smashing a major barrier
[130]
and paving the way for larger more
[132]
complex projects
[133]
[Music]
[134]
located just outside the city of um
[136]
perry's team is now working on the
[138]
largest 3d printed multi-family house in
[141]
europe with 380 square meters of living
[144]
space divided into five apartments
[146]
across three levels
[149]
so how did perry get into the world of
[151]
3d printing
[153]
here at perry we have let's let's call
[155]
it a think tank it's a department called
[157]
disruptive products and technologies
[159]
and they think about projects or
[161]
products and technologies that might
[164]
substitute our current core products
[166]
that might endanger our business model
[168]
in this department so various ideas are
[170]
always thrown around and actually
[172]
actively pursued so it's not just a
[174]
monitoring department
[176]
and one of the topics
[178]
even years ago was 3d construction
[181]
printing when we build up the printer on
[183]
a construction site directly on the site
[186]
and we start sprinting there that was
[189]
a moment for me which i where i realized
[192]
that we are printing that on site and
[195]
people will live in there so that was
[197]
for me a moment where i really said wow
[200]
that's not just um theory and that's not
[203]
just
[204]
in a lab it's it could it could happen
[206]
in in real
[208]
the homes were both built with cobord's
[210]
modular bod2 printing system a flexible
[213]
platform that can be scaled to suit
[215]
projects of varying size
[217]
the printer needs just two operators and
[220]
takes less than 48 hours to set up on
[222]
site
[223]
once up and running the system can print
[225]
as fast as a meter per second using data
[228]
from integrated design models
[231]
there's obviously there's been a lot of
[232]
firms around the world that have done
[233]
this a lot of research teams of 3d
[236]
printed buildings over the years and
[237]
there's been kind of different levels of
[238]
excitement around it why isn't it
[240]
widespread why isn't this just the way
[242]
that we build all of our buildings 3d
[244]
printing really affects the overall
[247]
construction process it has impact on
[249]
the planning side execution of the walls
[251]
but also on other trades and and the
[253]
planning and permitting all of these
[255]
things come into play here
[257]
the buildings that we've seen across the
[259]
globe actually have seen a steady
[261]
increase in let's say validity
[263]
so the first ones have been basically
[265]
kind of big 3d printed flower pots
[268]
where all the other trades have been
[270]
thrown in there but nobody's really
[272]
thought about how to integrate it into a
[274]
full construction process
[276]
maybe sometimes in the news and media
[278]
that hasn't been
[279]
it's always been portrayed like
[280]
everything was perfect but obviously
[282]
this has been a steady learning curve
[283]
and now we feel that we've hit another
[285]
milestone where we've now been able to
[287]
execute these permitted buildings
[289]
what perry have done in germany with
[290]
this building how is that different to
[292]
what we've seen before in
[294]
dubai the netherlands you know many
[295]
kinds of other places
[297]
we wanted to do
[298]
real world architectural scale
[301]
permitted residential buildings um so
[304]
we've done lots and lots of tests
[306]
to
[307]
to get this german building permit and
[309]
we have one of the toughest building
[311]
codes around so that's that's quite a
[312]
milestone to get these
[314]
completely normally permitted
[316]
residential homes and that's i think
[318]
where the very core difference lies i
[320]
have included project partners from the
[323]
start we are working directly with a
[325]
construction company we're working
[327]
directly with architects which don't
[329]
want just to make a demo project the
[332]
real project where later people will
[334]
live in it's a project where the
[337]
investor sketch rents out every month so
[340]
it's something which
[342]
will be used
[343]
and the other thing is i guess the the
[346]
speed and the size now it's the the
[348]
actually the biggest 3d printed building
[351]
in europe
[357]
perry also engaged a number of the core
[359]
trades on these projects a critical
[361]
hurdle that few other 3d printed
[363]
buildings have attempted to cross
[366]
with services and other works already
[368]
coordinated with the structural design
[370]
errors on site have been almost
[371]
completely eradicated saving time money
[375]
and waste material
[377]
while the savings may be modest here
[379]
they'd soon add up across an entire
[381]
estate or housing development
[384]
what kind of
[385]
real world savings have you seen on this
[387]
project so far this really this
[389]
integration of of other trades has a
[392]
huge impact um so we've had the
[395]
electrician come into one of these
[396]
buildings and he walks around and says
[398]
well guys you know i'll be saving up to
[400]
like 12 days in here
[402]
um so we are saving a lot of labor in
[405]
other trades because there's in the
[407]
buildings we're executing there's not
[409]
going to be a single slot that has to be
[411]
cut nobody's going to have to drill a
[413]
hole for a power outlet
[415]
though the design of these buildings may
[417]
feel relatively straightforward when
[418]
compared to some of today's architecture
[420]
the team are using the lessons learned
[422]
to construct larger structures in a
[424]
variety of forms
[426]
with german building certifications now
[428]
under their belt the team are planning
[430]
more projects using different materials
[432]
and with a focus on further reducing
[434]
waste
[435]
but while there is cause for optimism
[437]
we're still some way from the widespread
[439]
uptake of 3d printing and several
[441]
challenges remain not least breaking
[443]
into a traditionally conservative
[445]
industry
[446]
i mean securing german building
[448]
certification is a huge step for you
[450]
guys in a huge step for the world of 3d
[451]
printing what kind of other challenges
[453]
and barriers are there on the way
[455]
between where we are now and
[457]
this being the way we build our homes
[459]
buildings offices well it's a lot about
[462]
educating people really um to know you
[464]
know it's it's a different type of of
[466]
planning a building um it's different
[469]
for the contractor it's different for
[471]
the electrician it's it's different all
[472]
around for everybody involved so all
[475]
these trades now have to learn a how to
[477]
cope with this technology and how to
[480]
make the best of it not be threatened by
[482]
it but to to see the potential it can
[484]
have for these individual traits and
[486]
make their life easier and make
[487]
construction more safe and more
[488]
efficient
[490]
there's definitely a spot for all the
[492]
other conventional construction
[494]
techniques who are also evolving so
[496]
3d printing will play a very important
[498]
role we are convinced of that um but
[500]
this educational diffusion process into
[503]
the market will still take some time
[505]
would you live in a 3d printed house god
[508]
of course
[509]
right away i'd be all over the design of
[511]
that um i mean just having round shapes
[514]
which are also way more sustainable than
[516]
the weird rectangles we that we build
[518]
right now um definitely and you know
[521]
we've tested all of it so we know that
[523]
it's very very stable
[527]
while the technology has had its
[528]
challenges the success of perry's
[530]
project in germany marks a major step
[532]
forward and will stand as a powerful
[534]
case study for innovators rekindling the
[537]
determination to make this building
[538]
technique viable at scale
[541]
that 3d printed world we've imagined has
[544]
just moved one huge step closer to
[546]
becoming real
