In times past, building a working machine from scratch, such as a bike, has never been an easy and fascinating task. This process involves designing the bike and manufacturing the individual components before putting them all together during the assembly of the bike. This was a complicated process that required a full team and a variety of tools to complete.
There are significant advancements in the industrial sector in the 21st century. These sophisticated technologies make building and manufacturing relatively easy, fast, and effective. This state-of-the- art process can be witnessed in building with NEXA3D, a 3D printing machine.
Who is NEXA3D?
Nexa3D is an innovative manufacturing company that produces 3D printing technology that allows users to import and develop a prototype before further manufacturing the model.
The 3D printers are unique in that they deliver high-quality work even while multitasking at great speed and mass-producing items on a large scale. This technology is readily accessible and is already in use in many industries. Today, 3D printing drives the additive manufacturing industries, health sector, manufacturing of prosthesis, food and drink production, machine manufacturing, and the automotive industry. In the future, the technology will be adapted for use in many more industries.
What Makes Nexa3D Printers Stand Out?
Nexa3D printers make use of a powerful technology that allows you to quickly build anything you desire while perfectly adhering to the product’s design specifications. The Lubricant Sublayer Photo- curing (LSPc) technology makes it possible for Nexa3D printers to perform tasks efficiently and without the errors found in other types of manufacturing processes.
LSPc technology is an ultraviolet light-curing technology. A liquid resin is exposed to ultraviolet light, which causes polymerization and leads to curing. That resin is poured into a vat with the bottom made of a material permeable to ultraviolet radiation.
Underneath is a UV light matrix. The bottom of the vat is covered with a self-lubricating membrane that stops the formed model from sticking to the surface. The membrane also enables a high-quality print by ensuring that resin is delivered to all printing areas, regardless of the model’s solid or hollow shape.
The process of forming the model begins on the platform’s surface, resting in the resin a few tens of microns above the membrane. UV light is focused on the gap between the platform and the membrane to prevent peeling of the individual layers. Within seconds, the resin begins to harden, adhering to the platform.
The platform rises, and the “pattern” of ultraviolet illumination changes following its movement, forming the structure of the printed model.
The technology makes it possible to print an object without taking a break to lift it (for the next layer of resin to have access to the printing area), which is necessary with other stereolithography technologies. The absence of intermediate lifts results in a rapid increase in the speed and accuracy of printing. The surface of the model becomes perfectly smooth due to the absence of visible boundaries between the layers.
The Bike Building Process
With Nexa3D printing, the process of building a bike would only take a few hours to complete. Right from designing the prototype, the parts are modeled and annealed almost simultaneously, allowing you to complete the entire process in a short period of time.

With Nexa3D printing, the process of building a bike would only take a few hours to complete. Right from designing the prototype, the parts are modeled and annealed almost simultaneously, allowing you to complete the entire process in a short period of time.
The process includes:
- The chosen material is annealed or softened by heating before being hollowed out. These parts are reheated, pickled in acid to remove scale, and lubricated.
- The hollows are measured, cut, and precision mitered to the appropriate dimensions. Frame sizes for adult bicycles generally run from 19 to 25 inches (48-63 cm) from the top of the seat post tube to the middle of the crank hanger.
- Next, the hollows are fitted over a mandrel or rod attached to a drawbench. To achieve the right gauge, the hollows pass through dies which stretch them into thinner and longer tubes, a process called cold drawing.
- The tubes are shaped and tapered into a variety of designs and lengths.
- The tubes are joined into a frame.
- The assembled frames are adjusted by default during the Nexa3D printing process. In the conventional building process, making these adjustments would require hammering the tubes while the frame is still hot to eliminate any misalignment.
- The excess flux and brazing metals are cleaned off by the LSPc technology, a technology that prevents the sticking of the frame material to the building platform. This eliminates the need for pickling the bike in acid solutions before washing and grinding the brazing until it is smooth.
- The frame is first primed with an undercoat and then painted with colored enamel. The frames are painted not only to create a more finished appearance but also to protect them.
Conclusion
While this is a general description of the capabilities of the Nexa3D, it can do much more than you can imagine.
Since it’s only limited by your imagination, the Nexa3D printer can produce anything the mind can conceive 20 times faster than other manufacturing processes. Its flexibility and precision eliminate the need for excessive labor while reducing the time spent on the manufacturing process. Since there will be fewer separate parts, each item can be assembled faster as well.
Keep in mind that these are additional benefits aside from the reduced cost associated with using the Nexa3D printer itself.
