3D printing contractors

In the UK, almost a third of the waste comes from the construction industry. According to the Transparency Market Research Group, the construction industry worldwide will produce 2.2 billion tons of construction waste by 2025. And although most of the waste is related to the demolition of buildings, the construction sites themselves produce a lot of waste.

Conversely, 3D printing can reduce waste to almost zero. A 3D printer uses a well-defined amount of material that is required to print a design - no more, no less. This can be a big savings.

• Reduced energy consumption

3D printing in construction encourages the use of locally available materials and natural ingredients. This practice can reduce energy costs in transportation, construction and manufacturing, as most local materials require less energy to process or install. If traditional materials with toxic chemical impurities are replaced with natural ones, then the toxicity of the entire construction can be reduced. In addition, local materials are often better suited to local climates and can reduce a building's heating or cooling load, which also reduces construction costs.

• Save time and money

As with AI in construction, a 3D printer can run 24 hours a day, 7 days a week. This means construction projects have the potential to be completed much faster and a number of low-skilled labor costs can be avoided. What's more, 3D printing eliminates the need for temporary structures, such as formwork and scaffolding, that are commonly used in traditional construction. Studies of 3D printed concrete structures have shown a significant reduction in formwork requirements, reducing costs by 35-60%.

• Can realize unusual design shapes

One of the most attractive characteristics of 3D printers is their ability to create complex and unusual design designs, including a single, unique one. Since the job of a 3D printer is to layer the material, they can be programmed into absolutely any unusual shape that would be much more difficult to create with traditional techniques.

• Minimize human error and improve safety

The published injury statistics at the workplace by the American agency BLS in 2020 indicates that construction is one of the most traumatic areas and a high incidence of diseases. Every day, about 5333 workers die on the construction site. And with the advent of 3D printing, the number of work injuries and fatalities will obviously decrease, as it makes construction more programmable and automated. Robotic construction requires standardized, accurate and complete digital building information, making this technology more accurate and efficient, with minimal rework due to human error or any information inconsistencies. The usual problems with materials and components that need to be stored somewhere, protected from damage are leveled out, problems with installation and work in progress due to damage also disappear - 3D elements are created as they are built, they do not need to be moved and stored.

• Exploring new markets

The use of a 3D printer also allows construction companies to enter new market sectors that were previously inaccessible to them. And for start-up companies, having a 3D printer will be a competitive advantage. What's more, 3D printing is a brilliant way to elevate or improve the reputation of a construction company's brand among those who believe that concrete production has an impact on the planet's environment.

Distribution of structural 3D printing

3D printing for structural reinforcement, small scale components and structural steel could revolutionize design, construction and space exploration. In addition, the European Space Agency (ESA) believes that using 3D printed metals to create high-quality complex shapes can significantly reduce their cost, and they will become very common.

ESA has developed a project with the European Commission to improve the printing of metal components that can be used in space. In total, 28 European partners have united for the joint project AMAZE (Additive Manufacturing Aiming Towards Zero - layer-by-layer 3D printing for zero waste from production and efficient production of high-tech metal products).

Almost everything can be designed on a computer, so AMAZE plans to install a 3D printer on board the spacecraft, and as soon as an astronaut needs any part, a tool, he can simply print it.

Structural 3D printing

Civil engineering 3D printing

Civil engineering 3D printing has been gaining popularity over the past decade, as has the aerospace and biomedical industries. This revolutionary manufacturing technique is based on its unique ability to create any geometric shape without any formal restrictions, minimizing waste but increasing productivity and results. The construction industry's push towards automation has recently reached important milestones, including the creation of the first structures using robotic "arms" and 3D printing technology.

The use of 3D printing in the creation of structural elements from polymer materials, concrete and metals is becoming more common.

These civil engineering technicians can create freeform and innovative architectural designs using CAD-integrated software.

However, despite considerable research in the aerospace and bioengineering industries to evaluate and analyze this mechanism, there is still a lack of understanding of its use, the impact of 3D printed materials in civil structures, both in terms of material properties and structural response.

WIKI HOUSE - 3D printing in construction: what is the concept behind

Wiki House is an innovative project created by a small group of architects in London in 2011 . It offers an open source digital house design system that allows users to create, upload and share designs and print their own houses.

The kit does not require any special knowledge and training and can be created in 1 day. Elements are digitally cut from ordinary sheet material, like plywood, using a CNC machine. And it's much faster, less costly, and doesn't require the involvement of experts, as in conventional traditional construction.

A standard two bedroom house can be built for less than £50,000 and additional components such as cladding, insulation, windows and more can be added to the main frame of the structure. The first house that was built on the basis of the open source Wiki House technology was a two-story building. The 3D printed house was presented at the London Design Festival in 2014.

The Wiki House movement was spearheaded by Alastair Parvin, whose TED presentation "Architecture for People, Built by People" talked about the promise of 3D printing in construction. The creator of this project believes that Wiki House can help solve the housing problem, especially in emergency situations such as earthquakes (there is already evidence that 3D-printed houses can withstand shocks up to magnitude 8).

In the future, this could become a real alternative to low-cost houses, while allowing the customer to control the design of the project.

Will 3D printing be the sustainable future of building?

3D printing has the potential to revolutionize the supply chain and structure through a new method of design and manufacturing. According to the study, 3D printing can help the construction industry become more economical, more efficient and greener.

Saxon University of Applied Sciences scientists Ivo Kotman and Neils Faber claim that 3D printing technology will be a "game changer". They explored the possibilities of 3D printing concrete, and their conclusions are:

• 3D printing shortens the supply chain and the entire design process. 3D printing right on the job site eliminates time-consuming steps in the design process. The architects, engineers, contractors, clients, and executives who normally have to be actively involved in a project are no longer needed in 3D printing. Since all tasks can be combined in one figure of the architect, who uses the modeling method and reproduces the exact holistic designs.
• Pipe fitting and electrical wiring become easier and more efficient. Heating systems, insulation, plumbing and electricity all require the laborious on-site installation of conventional construction. However, in 3D printing, some of these features can be incorporated into the 3D printing process. Cavity wall printing is less resource intensive, improves insulation, and allows the use of 3D-printed hot or cold water channels. Moreover, the need for on-site installation is eliminated, which directly affects the reduction of waste.
• The best logistics. 3D printing eliminates 3 logistics and shipping issues. Firstly, a lot of materials and elements often deteriorate upon delivery, and if everything is printed on site, then damage is minimized

Secondly, in order to withstand transportation, the parts must be with increased technical characteristics, which by default increases the cost of them, and therefore the entire project. 3D printing right on the construction site will help to avoid such additional costs.

• Creation of individual house designs available to the general market. Usually, building a house with the involvement of an architect is an expensive pleasure for most consumers. But with concrete 3D printing, you don't have to worry about the chosen shape, it won't cost more. In fact, this means that in the future, more people will be able to buy houses of their own design, according to their individual needs

Reverse side of the coin

While 3D printing is definitely attractive, it's still important to look at it impartially, removing some of the promotional stimulus. Skeptics note several disadvantages of this technology.

• Research and development costs

Most construction companies operate with relatively low profitability. To start using 3D printing everywhere, significant investments will be required.

• Will consumers see this as a marketing ploy?

3D printed houses, offices, shops and other infrastructure are often impressive. But do most people really want to live or work in one? For most people, brick houses are much more familiar and attractive. Other technologies such as prefabricated houses also seemed like an attractive technology of the future for some time, but have not been widely adopted, despite the fact that in many cases they were cheaper than traditional ones.

• Difficulty integrating with other components

3D printers can create unique and interesting designs. However, if you need a building that will use different materials or different elements that will not be suitable for 3D printing, then it will be a challenge to include a 3D printer for the building process.

• Skilled labor shortage

With the current problem of a shortage of skilled labor in the construction sector as a whole, 3D printing will require an even larger set of specialized knowledge and skills, which will have to be selected from an already small niche of candidates. So finding specialists to work in 3D printing for construction may be another difficult task in the future.

• Construction quality control

Weather conditions can slow down the traditional building process, but things are even worse for 3D printing. The environmental factor for commercial construction may reduce the demand for 3D printing. What's more, quality control can be a much more serious task, requiring constant monitoring of the process by real people at the construction site.

• No standards and regulations

Despite the regular mention of 3D printing in the media, it still has not had a significant impact on the construction sector. There is an obvious liability issue when using these printers, even more so than human liability when doing some construction work. And quite a few other ambiguities regarding this technology. So until norms and standards are established, as well as rules in this area, 3D printing is unlikely to become mainstream in the construction industry.

How can 3D printing be integrated with construction?

At the moment there is strong evidence that 3D printing is worthy of attention and can be applied in the construction segment, and most likely that this technology will be used more in the coming years. True, it is not known how widely these devices will be used on the construction site, or whether they will remain only a tool for the manufacture of block elements for prefabricated structures. But for certain projects, it is reasonable to assume that 3D printers and this technology in construction will be a must-have tool in the arsenal of builders.

How to earn money with a 3D printer. Company's stats “3Dplast – a maker of plastic for 3D friend”

In this stat, let's look at the basic idea of ​​how exactly work can be done.

3 D other items for sale

The most logical thing you can do is to sell items that are made with the help of a 3D printer. Knowing about the feasibility of 3D-druk, but not dreaming of possession, the custodians want to take objects, which they can only find in their fantasies, or on armchairs. I joke for whom vikonavtsiv. You can sell your services to help your own site, through social media, on marketplaces and in any other way that is convenient for you.

In Ukraine, you can combine more of these functions on the Prom.ua platform, for example. І add to a new profile on facebook/or instagram, in the field of your target audience.

Vzagalі cool, like you have an idea of ​​what kind of product, like, what to name, “pіde”. Then choose the appropriate material, put your choice on the line, paint your working logo, and voila.

For example, 18-fold cotton Grant Gabrielson invented personalized molds for pouring chocolate for his clients using PLA or PP. Varto is cheap, even more demanding, easy to fight.

Your advantage can become stronger and more specialized trade, which you need, in the presence of strong competitors. For example, fans of cosplay will need different details for their costumes - if you know and trust you, you can become their main supplier of cosplays. The same is true for other souls - fans of the Dawn Wars, Marvel and DC comics, the whole world of Warhammer and so on.

Schwiedke Prototype

Request a service so you can contact professionals in the field of architecture, design, engineering and life. 3D-friend allows you to create large-scale prototypes for different purposes:

• demonstration of goods, objects and projects;
• presentation to investors;
• re-verification of the principle dії аbo vzagalі pratsezdatnostі probable product.

Why is it one of the most advanced methods of 3D imaging, because the FDM method has no other advantages in the field of swidish prototyping before any other technologies.

1. 3D-friend allows you to prototype quickly and at low cost.
2. Decreasing the amount of pardon in the design of the robe.
3. Item 1 means that it is easy to generate a small number of options for outdoor use with small spaces - not available.
4. Allows you to create prototypes of more folding end products.

For example, 3D-drugs will be ideal solutions for architects and engineers, who need to show their creativity – architecture or construction. Now I don’t need a check for a month, while fakhivtsy manually prepare layouts - finish every few days up to a week or two, so that I can take a 3D model.

Home-made products

The only way to earn money is to enter the home-made and hand-made market.

The most obvious butt - interior items "for the old times" can be broken for a few days and undoubtedly cost less, even if the master of the sprat was robbed.

You can work everything that your imagination suggests and that is requested by customers - a vase, lamps, lamps, household items, interior items.

For example, you can work fashion accessories for designers, as long as you know about them or you know how to make propositions for them. Or embellish for the quiet, who are looking for non-standard and individual options.

Work as a contractor

In the European Union, Great Britain and the USA, a number of service marketplaces are being established, as if they are signing an affiliate program for 3D printers. Seeing this is obvious - the company will take the contractor, you will take the appointment. Koristuvachi go to their site, publish those who need to abuse - the platform for spreading the word. Similar services can be found in Russia.

There are no such Maidans in Ukraine. I would like to promote the great gravity of the 3D market to a friend with our own partner programs. You can learn to wash them and become a contractor for vikonanny zamovlen.

Services “close” to a 3D friend

Really, to get to the market of a 3D friend, don’t obligatory buy yourself a 3D printer. You can buy a 3D-scanner and apply a highly specialized service 3D-scanning of the scanners, so you can help yourself. Abo help tim who give merit to the friend of the big figures of people for their photographs.

It is also possible to draw 3D models and sell them without intermediary or on specialized maidanchiks.

Before we talk, you can expand the software for 3D-friends - also required, but you need the skills.

Soup spoon

Thus, the 3D-druk market is actively developing and continuing its activity. But it’s hard to think that in this sphere everyone is “smeared with honey” and pennies flow like water.

Remember, there is nowhere without marketing. Like a daily business. If you just buy a 3D printer and keep checking customers - it doesn't work.

As a matter of fact, it is necessary to pay attention to the fact that you are with clients, with some pracciuvatimete. Apply mi pointed at the article. As a client, discuss with them the prospect of spying, and just start.

I do not immediately. Try to spoil everything - you can spend money and you can earn money. Understand that your business will be profitable.

Another obvious "spoon of dog" in 3D-druk, with which the novelties stick together, the most obvious looking details. Mayzhe zheden material does not give an ideal surface and details may be post-finishing. Also, to add parameters to each other on the level of the details - pardons in the whole process contribute to the whole result.

Ale, the quality of ready-made products is the key to proof and practice.
