For example, the automotive industry has used 3-D printing technology for many years for rapid prototyping of new auto part designs. The picture above shows a manifold prototype created by the Piedmont Triad Center for Advanced Manufacturing (PTCAM). In the 2000s, the Piedmont Triad Center for Advanced Manufacturing (PTCAM) was a partnership of schools and businesses that provided hands-on training in metalworking skills in North Carolina. Some of PT CAM’s training incorporated a stereolithography apparatus (SLA) by 3D Systems. SLA uses photopolymerization, directing a laser across a vat of liquid plastic called photopolymer.

When we first started blogging about 3D printing back in 2011, 3D printing wasn’t ready to be used as a production method for large volumes. Nowadays there are numerous examples of end-use 3D printed consumer products. This AI-assisted robotic printer has been able to achieve fast print speeds thanks to its innovative multi-wire print head. This print head allows for multiple metal feedstock wires to be fed into it at the same time, resulting in higher deposition rates. US-based rocket printing company Relativity Space has a super large metal printer, dubbed the “Stargate”. The 4th gen Stargate 3D printer is capable of printing objects measuring 120ft long and 24ft in diameter. Today, large-scale 3D printers designed to print concrete are used to pour foundations and erect site walls.

This can be used to make all sorts of things, from simple shapes to complex parts for machines. Binder jetting is a technology that uses a powder base material and a liquid binder. The printer lays a thin layer of powder onto the build platform, then selectively adds the liquid binder to bind the powder particles together, forming a solid part. A variety of materials, including metal, sand, and ceramic powders, can be used.

It is even possible for consumers to customize an edible item at a computer and then see their design materialize. You can ensure the quality of 3D printed products by using high-quality materials (plastics, metals, resins, etc.) and commercial-grade manufacturing equipment. It’s also important to make sure your employees and you have 3D printing expertise.

Two computer-controlled motors direct the flow of plastic along the length and width of the finished object, one for the printhead and another for the build plate. To create height, a third motor raises the rail the printhead slides across.

This method has almost no startup time or costs, making it ideal for prototyping. Parts can also be produced in almost any geometry, which is one of the core strengths of 3D printing. 3D printing is already transforming the manufacturing landscape due to its speed, affordability, high level of customization, and ability to produce complex geometries. As the technology continues to mature, manufacturers will develop new and innovative 3D printing solutions. The pandemic also introduced many new 3D printing innovations in healthcare, from mass-producing face shields to printing ventilator parts.

Step 1: Modeling and 3D Printing Software

While it is possible to print in a large range of materials, the most commonly used are metals and plastics. Some widely used plastics and polymers include nylon, polypropylene, ABS, PC, AB, HDPE, PS, PMMA, HIPS, and EDP. And commonly used metals include stainless steel, titanium, aluminum, cobalt chrome, and copper. But it is also possible to print in everything from paper to chocolate. To answer it fully, we’ve written a full breakdown of the cost of 3D printing machines in our article covering “How much does an industrial 3D printer cost? Think of your desktop printer adding a single layer of ink to a page to print a pattern designed on a computer. Now, imagine that the same printer was able to add multiple layers until that pattern was three-dimensional.

Computers are not like humans; they can’t just look at a 3D model and simply tell their friend ‘Mr. Lot’s of 1s and 0s are involved, meaning lots and lots of computer code. Once a 3D model is designed or simply downloaded off of a repository like Thingiverse, the file (these usually have extensions such as 3MF, STL, OBJ, PLY, etc.) must be converted into something called G-code.

Are there different types of 3D printers and additive manufacturing processes?

While injection molding requires manufacturers to design and create expensive tooling before producing parts, 3D printing enables them to simply send a digital design file to the printer. After designing your digital file and converting it to the correct format, it’s time to prep the model for printing. This phase involves slicing software, which helps the printer understand the design using coordinates that tell it where to deposit the material. The printer bases the printing process on a 3D digital model of the object, so the first step is to create it. Various CAD modeling software options, such as Creo, Catia, and Solidworks, offer the necessary tools to create this model.

Advantages and Development of 3D printing

The roughness of the surface can be minimized with the right print settings and a high-quality printer. However, using a post-printing process will yield the best surface finish. Sanding and painting is the most well-established method used to smooth 3D prints. It is relatively cheap and creates great results, but is labor-intensive. Sanding a 3D-printed part is the same process as sanding other products. Start with a low grit and work your way up to a high grit until you achieve the desired result. Going up to 200 grit sandpaper will create the best results but is very labor intensive.
