    thanks for sharing this. 3d printed housing is coming and this type of research is going to help it become incredible

    Excellent modeling of the nozzles. Did you conclude that (for that mortar mixture) the side trowels and leading closure plate do not improve the surfaces? Thank you!

      The nozzle without side trowels has problems to keep the top surface flat in the curves of the printing path; it becomes more inclined after every layer. Therefore, we prefer to use the nozzle with side trowels that overlaps the previous layer. This gives the best results; a bit similar to slip-forming ;-). A leading closure plate destroys the top surface of the previous layer, which leads to a lower layer adhesion (perhaps a vibrating leading plate can help reduce this effect. We have not tested this.).

      @@Concre3DLabGhent We have experimented with porous surfaces that have water behind them. Low pressure very low flow rate of water - to smooth the surface and help prevent plastic cracking in the sun/wind. Also experimenting with vibration. It has been surprising how much the material will take without causing collapse, if it is confined between trowels.

    Hi, please provide the machine specs, such as length x width x height ( max) possible with the machine. Is it gantry based or autonomous?
    Great quality 👍👍

      It's a robotic arm: ABB IRB 6650 - 125/3.2 type A, with an S4C+ controller. So horizontal range is 3.2 meter without arm extensions. Maximum object is in the range of 4(x) x 2(y) x 3(z) m I would say.
