3D printing remodelling the construction industry

October 26, 2018

The 21st century is emerging as the 3D age, and it is no wonder that the once novel technology has found its way into the construction realm. The aim is to print large structures and realize complex projects. The applications for use in construction seem self-explanatory, since building something from basic materials is what the construction business does.3D printing machines provide a wealth of applications beyond reducing the length of a supply chain. Eventually, 3D printing will become a common or even standard feature in the fabrication process.

Construction industry
In the construction industry, 3D printing can be used to create construction components or to ‘print’ entire buildings. Construction is well-suited to 3D printing as much of the information necessary to create an item will exist as a result of the design process, and the industry is already experienced in computer aided manufacturing. The recent emergence of building information modelling (BIM) in particular may facilitate greater use of 3D printing.

Construction 3D printing may allow, faster and more accurate construction of complex or bespoke items as well as lowering labour costs and producing less waste. It might also enable construction to be undertaken in harsh or dangerous environments not suitable for a human workforce such as in space.

The benefits that 3D printing can have on their bottom-line.

Reduced Supply Costs
China-based 3D printing construction company WinSun “expects 3D printing will save construction companies up to 50 percent on the cost” of building a house. This could prove to be a lifesaver for construction managers with access to this technology and could lead to increased competition within the construction field. Competition means lower prices for consumers, which could mean a shift from a rental to an ownership mindset.

Global Development
Often as automation and mechanization rise, prices drop. 3D printing is an affordable way to create housing for the impoverished in need of adequate shelter.

Greener Construction
Wealth Daily suggests that with the advent of 3D printing. The use of lumber in the home’s framework would be spared. This is a great advancement for green construction firms and a frightening development for the lumber industry.

Improved Project Planning
An important part of every project plan is the design. With 3D printing, companies will be able to quickly and inexpensively create models to have a visual representation of the project as well as help pinpoint problem areas and avoid delays.

Streamlined Client Expectations
With 3D printing, construction professionals and their customers can communicate more clearly and efficiently. Even a customer with no architectural background can better express his needs and ensure that everyone is on the same page. Much of a client’s expectations come from an idea, and 3D printing makes it simple to materialize that idea beyond the dated method of pencil and paper.

Despite the incredible potential, many construction professionals remain wary of the effect 3D printing could have on their business. Increased automation and mechanization have been detrimental to fidgety labour markets in the past. Take farming in the United States, for example: in 1900, the farming industry made up 38 per cent of America’s workforce but, in 2017, comprised less than 1 per cent. Some are even claiming that 3D printing could pose a threat to predictions of a boom in construction-related jobs.

What’s Next for 3D Printing
Among those calling for construction professionals to take advantage of the potential of 3D printing is University of Southern California professor Behrokh Khoshnevis, creator of Contour Crafting. In a Ted Talk he gave in 2012, he said, “If you look around yourself, pretty much everything is made automatically today—your shoes, your clothes, home appliances, your car….The only thing that is still built by hand are these buildings.” And later: “Construction, as we know it today, is wasteful, costly, and often over budget.”

3D printing will most likely not solve the construction industry’s skilled worker shortage, recruit up and coming talent, or remove human error in planning construction projects. It seems clear that 3D printing presents promising opportunities for the construction industry to become both greener and more cost-effective, often by considerable margins. As 3D printing research continues to develop, it will be exciting to see the benefits the technology will have on the many facets of the construction industry.

COVID-19 Measures – Update 10 Mar 2021

 

Dear Esteemed Clients & Partners,

As you are all aware, the Authorities enforced a second lockdown effective as from today, and as they continue to recommend or impose new measures in an attempt to contain the contagion, we would like to assure you that at Digiconsult, we are well-prepared to continue to serve and work with you with the same level of efficiency and quality as before.

A number of measures, as part of our BC plan, have been actioned. Be assured that our employees are trained to assist you remotely, while ensuring confidentiality and integrity of our projects. We expect to shortly transition from remote assistance to physical assistance once the Authorities re-activate the WAP (Work Access Permit).

We will ensure that there are no disruptions to our service delivery. Please feel free to discuss with our people about your specific requirements and any impacts that you foresee in the present circumstances, such that we can continue to work with you and your teams, as efficiently as possible.

We continue to prioritise the health and safety of our people and strive to provide you with the service standards expected throughout the pandemic.

 

STAY SAFE & STRONG….

Kind Regards,
