* Disclaimer of warranties: The following document is not intended as advisement, past results are not indicative of future occurrences, information is subject to change without notice due to the inherent nature of the emerging technology.
1. How many popular houses, for example: 70 m2 (1 living/dining room, 1 bathroom, 2 bedrooms and one kitchen this machine can build per week and or per month?
While this is conditioned on several extraneous factors such as availability of locally sourced materials, night-time construction capabilities, and requirements such as HVAC and MEP, our best estimate is 1 house per four days under ideal conditions for our current system. A 700 square foot habitat would require setting up/breaking down the current version of the machine at least twice. A 350 SF cabin would therefore take less than half the time due to the current logistical considerations. Our second generation machine can be expected to solve these logistical timing issues, and together with further integrated technology and greater capabilities can be expected to reduce that timing further. However we will not be accepting orders for the second generation machinery for at least year, and more likely a year and a half. It should be noted that the system can produce all of the infrastructure for an estate including;
Estate Property Line Walls
Pavement with embedded piping
Furniture, Interior Design
2. What will be the necessary sand quality/quantity (in tons) to build one complete house?
Estimated at 40 cubic yards of crushed and granulated aggregates.
3. Which king of reagents will be used and where them can be find?
Aggregates can be sourced locally from a nearby rock quarry. Certain added materials, such as glass fibers, recycled polymers, or cellulitic fibers can be used to supplement the aggregates. The liquid binder can be produced mostly on site, from the water table.
4. What is the actual price for the reagents?
The price expected for the reagents will vary by location, currently our best estimation is on the order of $50 per cubic meter. By comparison concrete casting costs around $250 per cubic meter.
5. Which kind of ceiling /roof and any other necessary product will be used in the construction?
While the machine can print roofing panel structures, the benefit of the system is more clearly manifested by the ability to produce roofing infrastructure for solar panel hardware. Additionally other products necessary will include electrical wiring, hvac, water heaters and cooling apparatuses, windows, and doors.
6. What will be the construction direct cost for each house (without considering land price, electrical and plumbing costs)?
We currently estimate the cost to be 1/4th the cost of traditional construction applications.
7. Can this machine be removed, after the completion of each construction project? (I need to have an idea of the time needed and cost projection for this operation. Is it necessary to disassemble/assemble this equipment?).
Yes. With the version 1.2 Reef Printer system, which specializes in paneling (connected by metal brackets and bracing), is remarkably mobile and requires only limited onsite assembly. The eventual version 2 system will be fully mobile and further reduce onsite logistical considerations.
8. Which kind of maintenance the equipment requires (cost estimation)?
Limited maintenance. New adaptions of the technology including our automated deposition system and evacuation system prolongs the lifetime of the machine. Maintenance will most likely take the form of onsite fabrication calibration for higher resolutions and for cleaning. The company will continue to design and build aftermarket modifications for our existing machine series, however they will eventually be phased out with the development and arrival of our next-generation machines.
9. Can we adapt/modify locally the construction software?
Yes. We are currently developing a next-generation software system that will integrate Heads Up Display technology with Building Information Modeling through Autodesk.
10. Is it necessary to have a special facility for the equipment?
No, however the system can function within the just-in-time manufacturing paradigm, for onsite delivery. We would recommend a tent enclosure, though the system can be operated in an outside environment. Additionally, for site preparation we would suggest excavation of the granulate reagents, temporary silo housing for the crushed and processed granulate reagents, and temporary silo housing for the liquid binder refueling. The next generation machine will build on our expertise in architecture and construction to provide a truly mobile site solution for the market.
11. Can we buy the equipment or lease it? Will the manufacturer be interest in participating in our joint venture?
We are currently looking at 3 year leasing models with priority right of renewal, with an expected lifespan of 6 years before the system can be retrofitted. We can also consider a “phase out” of the generation 1 machine for the next-generation machine, and also a running development cycle of after-market modifications. Currently, we see great opportunity for South America and the development of 3D printing building technology into the existing construction paradigm. With our next generation machine, the system will be an amalgamation of standardized/universal mounts and chassis by approved manufacturers combined with unique hardware components and elements. This will enable the development of the industry through reduction in the customized cost that constrain the current version. The license is negotiable, but we would want to seek an annual dividend payout, and the $250K Euro is a hard non-negotiable cost for the production of the machine. FOB Italy, currently, although it is possible we will manufacture and build the system in the U.S. for shipment to South America.
12. What will be the initial necessary cash flow?
We estimate the necessary initial cash flow will be limited to staff, materials, architectural designers, and building permit filing. We estimate these costs to be similar to those costs undertaken by architecture/construction companies in their early capitalization phases.
13. Is it necessary to have a special training to operate the machine? If affirmative where this training can be done, what will be the duration of it and what will be the cost?
The machines should function with minimal training, while we have not yet fully detailed out our training, we are working on developing a certification course, which could be offered in the U.S. or in Italy. Additionally we have incorporated a warranty model into the lease which provides for reserved capital for our maintenance engineers to travel onsite to ensure functionality and operation of our technology.
