We are getting ready to deploy this technology on the next scale and this video was really helpful. A little down to earth howto in place of the usual bot making walls thing.
Very few videos on how these things work, thanks for this! I have a design in mind but it would have a fairly heavy print head. Basically a worm screw that can pressurize a small area right before the nozzle, it works in sync with the motor to regulate the pressure! Say bye bye to oozing if the worm screw and motor kill pressure at same time and its not like with a regular plastic printer where it might clog, the worm screw will force the mud through easily and you could even implement a retraction with the worm screw on the print head, only thing that would leak would be the small bit in the nozzle! Not sure how the pump motors work though
Definitely the coolest and most informative of any video like it. Nothing like outstanding homegrown innovation still clad in tyvek! The only facet I can find missing is locally-sourced mortar.
SpaceCrete was here!!!! You have been inspiring myself with you're 0 slump mix of concrete (you have an answer). I did find Fitzpatrick has somewhat affordable retarders and accelarators per cubic yard of concrete. I think with Jarett videos and you're mixture expertise the brave DIY with Arduino knowledge and a small budget may have a go at it.
@@pedrotorres9836 Very nice to hear back from you! Citric acid is pretty good to retard if you want to wake it back up fast. But there probably is a better one - for a local-materials-mix with more open time, less cement, and fast build. Stay in touch!
Hadn't watched this video in while. You could include it, or something similar in your course. I bet they've come a long way in a year! The steppeing of the process is great! -Carlos
Have you done any detailed video about the machinaries... manufacturing Company, service, machinary review, maintenance, machinary cost according to its variants, etc..
Look at how expensive all that equipment is, what products do they produce that justifies that expense? I mean there are also a few people babysitting that expensive machine. Looks like they could just produce these shapes themselves much faster than watching a hugely expensive machine do it..
How do I find a good mix and would Portland cement be strong enough for a 1 cubic inch layer for a height of 10 feet or what ratio should I add of other materials ?
This is brilliant id love to learn this but wouldn't know where to start, there is a masters course on this in the UK but I dont want to do that because lecturers maybe protective of their knowledge and then ill just end up with a piece of paper. The other way is to dive in but need alot of capital
Loll then I am in an even worse situation by taking 3DCP as a undergraduate final year project. My lecturer just dropped me a topic without teaching my anything, and I have to learn everything from scratch, sometimes watching these youtube videos in hope of finding some insights...
start with a small one, for example getting the nozzle part right with the right mix first. 3d printers still has a long way to be improved so more people is always better
We should be printing 2 story houses for like foundation + 5k labor + cost of cement + 10% which is hardly nothing. I can't wait for someone to simplify this into a dome maker which costs almost nothing to source.
Cost of electric, plumbing, (from grid) windows doors roof ect… that can add up to more than the foundation and printing mortar fairly quickly. 5k labor seems about right but you’ll also need another $10k+ in equipment rentals. If you can do stuff like that yourself you can save money buy that isn’t scalable most people aren’t handy enough.

Looks great! I wonder what the costs are? Compared to Wood or steel buildings! Could a 275`x 60`x19` (divided into 12 bays) building be done in Ontario?
@@automateconstruction I thought it might be ! But it would be amazing to see it go together! Getting quotes on Metal and wood construction! I would consider 3D for sure!!
Anything about the amount of chemicals it takes for this type of concrete to holds its “ Shape “ ~ There is a lot of chemicals in this type of printed concrete / and shot-crete as well. And concrete is not enviromentally friendly even without all these chemicals.
Seems like a production nightmare. So many things could go wrong with mix design consistency/quality and mechanical issues. Also what about evaporation rates and questionable curing practices…
Very well done Jarett, its nice to have a 3DCP advocate out there educating the industry on this disruptive tech. Keep up the good work!

and then a few more googles later i find this is already a thing, the main problem is the pumping
Thank you Jarett 💙

I am in Sarasota, FL. Looking into this for our company! So exciting!
This is incredibly interesting! Thank you so much for sharing
Thanks man! This is extremely excellent insight. Keep up the good work!
I have watched this video many times it is the most informative and am wondering if you give tours?

This is a really interesting video, great job! 👍

Can we make load bearing concrete pipes with reinforcement cage and aggregate

Hi, thank you for sharing this video. My question is what happens to the concrete that is left over when there is a clog. (9:00)?
Either discarded or recycled. Sometimes if it’s still wet you can put it in a prepared form.
How do I find a good mix and would Portland cement be strong enough for a 1 cubic inch layer for a height of 10 feet or what ratio should I add of other materials ?
Great Video!
Which type of mixer was used here and what's it mode if operation please
did Twente produce the machine used for the printing or did they purchase it ?
They purchased the parts and then produced the machine. They’re also working on some new models that print outside the facility.

@@louischan8062 I almost forgot, construction materials! isn't just concrete trying new materials could improve the printer part.
Do you guys do your own mix design or you buy in super sack
Interesting video. Do you know why they use a different nozzle in some shots?
Might be the difference between 1k and 2k material.
Managing your hose is very important
That's what she said
Looks like a pretty big investment. Hiw much would one such machine cost. More or less?
The one in the video runs 7 figures

That would be quite the challenge and would require quite a bit of creative problem solving beyond the current state of the art.
@@automateconstruction I thought it might be ! But it would be amazing to see it go together! Getting quotes on Metal and wood construction! I would consider 3D for sure!!
It’s great, but I am worried about how to use this machine onsite outdoor
They’ve got one in the works to do exactly that. Other companies print on site as well I’ll be releasing a video on one of those soon.

9:46, what is the rebar? Stainless?
I believe it's fiberglass
I have a laptop like that I gues I can join

I live in Pensacola Fl and wondered if anyone knows of any 3D printing companies near me thanks
Printed farms is in Wellington Florida
