Frequently
Asked Questions
1-What do you think is the greatest advantage of using 3D printing as a form of construction?
3D printing as a manufacturing process is a great added value in the construction processes, providing industrialization and continuous improvement in a sector such as construction that has been anchored for years without evolving.
This evolution of the construction system offers greater speed of execution, savings in production costs and of course the versatility and freedom of forms without cost overruns. In addition, reduction of waste and CO2 emissions, as well as the possible use of cementitious materials that use mixtures with recycled materials or waste, as the main consumable.
Execution control is another very important advantage when applying this type of system, since the machine is an element that accurately performs the entire process indicated to it.
2-How many people are required to operate the machine to build 55m2?
3 people are required to operate the machine:
1 BE MORE 3D qualified machine operator.
1 First mate who places reinforcement, pre-frames and electrical and plumbing pre-installation.
1 labourer in charge of supplying the material to the pump, either by 25kg bags or 1000kg bags.
3-Approximate time in days or hours to assemble the machine and print the 55m2?
The assembly of the machine is done in about 5 hours approx. with 3 operators and the help of a forklift, without the need for cranes.
A 55 m2 house can be printed in approximately 6 hours.
The time needed between house and house, including the displacement of the device is 1 hour.
4-Does this construction system comply with building regulations?
Of course it does! Our devices have CE approval and marking, which allows you to build safely, in terms of building regulations, complies without problems with the technical code of the Spanish building and structural code. as it is a construction system similar to building with concrete blocks or thermo clay, as contemplated by the standard, are safe and certified systems for buildings up to two floors without the need for pillars.
5-Can I build in a country with earthquakes, can I build pillars?
For the construction of pillars in houses to place reinforcements vertically and be able to resist earthquakes, we have designed a simple system based on 3D printed hollow columns in which the pillar reinforcements are inserted and filled with concrete, leaving a constructive pillar resistant as the one of a lifetime (see more info in annex seismic).
6-How are the walls built (are they hollow or filled?)?
You can print walls of different shapes and thicknesses, filled or hollow, with or without zigzag, the device comes with various sizes of extruder nozzle. It is the decision of the architect or builder, depending on the stresses to be supported, traction, compression, seismic…
BE MORE 3D, can give technical support on these issues with its previous experience in 3D constructions, during the training time and later, with help in designs and other post-training investigations.
7-How are the installations solved to fit out a space?
Regarding the installations, they can be placed embedded in the wall, placing them while printing horizontally and making the rubbing/rubbing easily before the material hardens, vertically, as well as holes for the passage of pipes and installations, either single wall or double wall.
Another option is to place the installations on the wall once it has hardened and place a double sheet of plasterboard or drywall.
8-How is the structural system, how are the foundations, how is a 3D print anchored to the floor level?
The structural system is based on load-bearing walls that work in compression, the recommended foundation will be the one established by the geotechnical study and the structural calculations based on the type of soil and the loads of the object house, being the most usual a slab or footing under the wall, for the installation of the guides, they can be mounted on the slab itself, on a screed attached to the foundation or on a well compacted ground and as level as possible, the guide system is levelable, so it can absorb a certain unevenness, about 5 cm.
Depending on the construction zone, whether it is seismically active or not, it can be built in different ways, with a simple joint supported on the slab itself or generate joints by means of reinforcement overlaps with joint bolts (see seismic annex) and 3D printed hollow columns which are reinforced when reaching the slab height and are filled with concrete later or during the concreting of the slab.
9-What about the warranty?
The equipment has a warranty of 12 months, which can be extended to 24 months, within the warranty, the manufacturing company, BE MORE 3D, will be responsible for the repair and replacement of any problem or manufacturing fault that the equipment may have. The manufacturing company will not be responsible for problems or failures caused by misuse of the device. However, it will provide support to solve any problem regardless of its root cause.
