Another survey conducted by Sculpteo revealed that 93% of people considered 3D printing as a competitive advantage in their business model. This trend of low-cost, rapid prototyping along with full customizability is enabling a new wave in manufacturing. The process of 3D printing is a no-waste process, which allows companies to streamline their development and prototyping processes while also reducing costs and improving lead times. 3D printing is truly a disruptive innovation in manufacturing, much like the printing press did for the mass production of printed materials and the dissemination of knowledge.
Many businesses contract out the model design process to another business. However, you can learn how the process of turning an image into a digital model which will be used for 3D printing.

There are several 3D printing technologies and they all work very differently. What all the technologies have in common is that they are additive.
Material Extrusion
3D printers are machines, and just like cars, they require regular maintenance. If you’re not one to enjoy tweaking or DIYing things, then a consumer-level 3D printer may not be for you. Slicing software will then translate your 3D model into lines of code that represent very-thin layers. You can think of this as cutting a vegetable into paper-thin slices. In simplest terms, the filament (material) is pushed through a heated Extruder at a continuous rate, while the Extruder moves around the X and Y-axis.
They used this method to make a bio-inspired robotic hand that combines soft and rigid plastics to make mechanical bones, ligaments and tendons, as well as a pump based on a mammalian heart. Step one – Creation
First in 3D Printing is to create a blueprint slash three-dimensional digital file of the object we want to print. The most common way of creating a digital model is with Computer Aided Design – CAD.

Both these techniques are heat-intensive and thus require support structures. Once the process ends, the support structures are removed using CNC machining or manually. Parts are then thermally treated to address residual stresses during post-processing. Consumer products, without a digital or electronic build quality, such as clothing, eyewear, jewelry and more, can all be mass-produced through 3D printing. While various other products can have their body or frame manufactured through 3D printing, any item that can be produced within a mold can also be produced through 3D printing. 3D printing has been utilized in the automotive industry for many years, allowing companies to shorten design and production cycles while lowering the amount of stock needed to have on hand.
Since then, the field of 3D printing has grown exponentially and holds countless possibilities. Sharp corners create stress concentrations, so corners are the most common geometries that induce warping.
On the other hand, SLA relies on a single-point UV source or laser to cure the liquid. Excess resin has to be cleaned off the output once printing is completed, after which the item must be exposed to light to improve its strength further. Support structures, if any, will need to be removed post-processing, and one can further process the part to create a higher quality finish. These metal 3D printing techniques create components with high-quality physical properties, sometimes even more robust than the base metal used.
On this new liquid surface, the subsequent layer pattern is traced, joining the previous layer. Depending on the object & print orientation, SLA often requires the use of support structures. When the base technology was first invented in the 1980s, the term was used to describe it because, at the time, 3D printing was only suitable for creating prototypes rather than production components.
Powder bed fusion (PBF) technologies use a heat source to induce fusion (sintering or melting) between the particles of a plastic or metal powder one layer at a time. Selective Laser Sintering (SLS), electron beam melting (EBM) and multi jet fusion (MJF) all fall within this technology. The metal 3D printing processes selective laser melting (SLM) and direct metal laser sintering (DMLS) also use powder bed fusion to selectively bind metal powder particles. Digital Light Processing (DLP) is the fastest of all 3D printing methods. A layer of hardened material can be printed in a few seconds and quickly transferred to allow for printing of the next year. Like SLA, DLP 3D printers use liquid plastic resin but instead of a UV-laser beam, the resin is melted with arc lamps.
