I'm back! I took a break for a while since we've been busy gutting and remodeling our first house. I've learned a lot about the reality of building construction and I'm excited to incorporate this new knowledge into my new videos.

$Fibonacci 3D printed house | Good, Bad & Ugly Eight hours away from Calgary, in a small community called Procter sits a curious-looking 3D printed concrete house. This is the Fibonacci house built by Twente Additive Manufacturing or TAM. It is a 35 m2 or 375 ft2 tiny house, shaped like an extruded Fibonacci spiral. Link to my Patreon page: https://www.patreon.com/Belinda_Carr Chapters 0:00 Introduction 0:58 How its made 3:58 Good 6:25 Bad 7:26 Ugly 7:59 Conclusion An outline for the foundation was printed in the factory in separate parts. Insulating foam was sprayed inside and outside the foundation perimeter. Concrete was pumped over the foam and levelled off. Next, 20 separate wall pieces were 3D printed in the factory. The house was made with K1 concrete mix, with an accelerant mixed into the concrete. All you need to do is add the right amount of water and pump it out of one nozzle. Polyurethane foam insulation was sprayed in the cavity in 12 to 14” increments to ensure complete curing. The house was painted with a grey elastomeric paint with 300% elasticity for additional water repellency and to bridge microfractures. Two 3d printed concrete columns in front of the house support a massive wooden canopy. These were printed with a more expensive K2 concrete mix, where an accelerant was added right before pumping, at the nozzle. The walls were printed and installed in 5 weeks by 4 workers for $6000. However, finishing the rest of the house brought the total cost up to $100,000. An open plan kitchen and living space are on the first floor of this tiny home, with a shower room tucked inside the narrowest part of the spiral -shaped floor plan. The upper level is reached by a ladder. It can accommodate 2 adults and 2 children. This is the first fully 3d printed home on airbnb. Let’s discuss all the good things about this project. The Fibonacci house is not just form for form’s sake; they chose a spiral because it would have been very expensive to make this shape with traditional formwork. Printing a curved wall with different radii is not an issue when using a 3D printer. TAM even 3D printed a sculptural table leg and bathroom sink to show off the versatility of the robot. The front door handle is in the shape of a Fibonacci spiral. The quality of the 3D printed beads is excellent. They were straight and even, with very few wobbles. They have printed staircases on sloped land and a modern day stonehenge with sculptures and seating. They have 3D printed a small section of a wall with minimal connections to reduce thermal bridging. When we visited their factory, they were printing concrete wall shingles. They are very transparent and aren’t afraid of showing their mistakes. They showed us how much work goes into cleaning 3D printer nozzle heads and machines: an essential phase that every other 3d printing company hides. There are a couple of bad things about this project. The lack of adequate insulation at the perimeter of the foundation makes the floor very cold. I use a FLIR thermal imaging camera to see how much heat was lost at the base of walls. Concrete wants to expand and contract at the same spot. Since the house was designed with offset joints, visible cracks have formed on the exterior wall. Also, despite being made from a single 3D model, the curved walls do not align. Inside, many electrical outlet plates are loose. Now, the ugly. Like I said earlier, the people working for TAM are extremely creative and willing to learn, but they aren’t trained architects, engineers, construction managers or experts in this field and it shows. The beautiful, fun concrete shingles have gaps in between and are screwed directly over Tyvek. There’s no flashing at the top of the windows or the door. There are large gaps at the front door which lets in cold air and bugs. We killed about 50 spiders in 3 hours before bailing. There’s a quote that “repetition leads to mastery”. We can’t do something once, be satisfied with an average outcome and move on. The house and all the other projects on their site are fun and have so much potential, but they are desperately lacking refinement. I see TAM as a jack of all trades and a consultant to many other businesses in the 3D printing industry. But I’m not sure what they are best at and what they want to focus on.
