3D printed concrete is an emerging technology that has many advantages like reduced labour cost, less emission of carbon dioxide in the atmosphere, reduced cost, less time consuming, ease of use, ability to change properties as per desire and many more. A case study on building houses using 3D printed concrete and conventional concrete brought into light that cost is effectively reduced using 3D printed concrete which is beneficial for people having low income or for refugees who have nowhere to go and construct houses affordably. Many types of 3D printing can be observed out of which the perfect method is selected based on various criteria. Some admixtures can also be added for better strength and workability that will facilitate ease of extrusion through the nozzle. Compaction or vibration is seen absent here as the process is completely automatic. However, some labours may be needed to move the 3D printed elements from one place to another. Other properties like bond strength, compressive strength and flexural strength are also taken into account for monitoring the effects of standoff distance as well as printing speed on tensile bond strength. Apart from this, some future projects are also expected that can produce homes on other planet and can open an array of opportunities.
