3D Printing in Construction: 5 Common Challenges and How to Overcome Them

Although the application of 3D printing technology in the building industry offers some advantages, there are still several hazards that need to be managed. Still, it is quite important to know about these possible issues in order to guarantee a safe and efficient execution.

1. Contract Liability and Insurance Challenges

It is possible for any kind of machine or technology to experience a breakdown in its equipment, just like the technology that generates 3D prints. This risk may be encountered during the delivery process, during the setup process, or even during the operation process. Considering the expensive cost of the printers which can range from $50,000 to $1,000,000 for a powdered metal commercial 3D printer and the relatively conventional nature of the printers, owners and managers may be tempted to take shortcuts.

Additionally, there is the possibility of fire dangers, which can vary according to the material that is used and the energy that is utilized to drive the printer, such as oil-based hydraulics. The hefty cost of replacing a broken or faulty printer is not the only thing that contractors may have to worry about; they may also be forced to delay projects for several weeks while they wait for a replacement. Nevertheless, maintaining the printer and the equipment in accordance with the manufacturer's specifications and performing maintenance on a regular schedule is something that contractors should do in order to avoid these hazards.

2. Mitigating Equipment Breakdowns

On projects involving 3D printing, coordination among manufacturers specializing in this kind of manufacturing, technical companies, and building companies is usually necessary. The formalization of these connections is typically accomplished through the use of joint venture agreements (JV). Under the 'joint and several liability' theory, every member of a joint venture is equally and severally liable for any losses the project may suffer independent of the individual inflicting those damages.

3. Increase Occupational Diseases and Workers' Compensation Claims

Emerging technologies in the building sector demand workers to learn new skills as well as new hazards to their safety. If workers are not given sufficient protection and training in 3D printing, employees could be more prone to experience accidents that will lead to workmen's compensation claims.

4. Construction Defects

Failures that involve poor design, nonconforming building materials, improper installation procedures, and maintenance oversights are generally the causes of accidents that result in construction defect lawsuits. There is also the possibility of problems occurring when traditional building components, like windows and doors, are combined with 3D-printed elements, like walls. Some windows, for instance, will only function properly if they are constructed out of particular materials that have been specified by the manufacturer. Also, when hiring subcontractors who are not knowledgeable about 3D printing, there is the possibility of defect claims.

5. Cyber and Intellectual Property Risk

A product that is printed using a three-dimensional printing process is developed with computer-aided drafting (CAD) software, which generates files that may contain confidential information. It would be catastrophic for businesses if those files were lost or stolen, as it may result in digital sabotage or theft of architectural designs.
