The Industry of the Future

By Uncategorized

3D printing is the newest and most technological production system in the industry.

We are talking about innovation and therefore Industry 4.0, digital technology capable of overturning traditional production paradigms.

 

Additive manufacturing? What is it?

It is a real revolution, production no longer takes place by removing material from solid …. it starts with a virtual 3D model and then, thanks to the use of special 3D printers, it is “printed” layer by layer, as happens in ink printers we have at home or in the office.

The additive process in the production phase is characterized by a printing cycle in which these innovative machines allow the creation of extremely complex geometries.

But what needs to be kept in mind is that it’s not just FFF technology, there are multiple printing technologies!

The most used printing technologies in the industry

The first thing to understand is that using the term 3D printing is very generic, because it identifies a group of additive manufacturing processes of an artifact.

The ISO / ASTM 52900 standard, created in 2015, seeks to classify the different types of 3D printers in the most specific way.

In total, seven different categories of additive manufacturing processes have been identified and established.

BUT … in the industrial sector, the most used technologies are three:

  • FDM
  • SLA
  • SLS

 

 

FDM

FDM stands for Fused Deposition Modeling

The most common method used in the additive world is that of FDM printing which is based on the use of thermoplastic materials, melted by means of a heated extruder.

A three-axis system moves the extruder along the XY axes until the definition of the first print layer on the print platform is complete. Once the first level is completed, the extruder moves along the Z axis and resumes extruding material to define the new level.

The repetition of the printing cycle and the overlapping of the layers composes the final geometry.

 

SLA

The SLA (StereoLithography Apparatus) process is based on the combination of a liquid resin that is photosensitive to a beam of ultraviolet light to solidify the resin.

This type of printer uses mirrors called galvanometers, positioned on the X and Y axes, to point a laser beam through a resin tank.

A section of UV liquid resin is selected which solidifying layer upon layer forms a cross section of the object within the printing area.

This method has been used for some years above all in the dental and jewelry sector.

 

SLS

Engineers and manufacturers from different sectors rely on 3D printing through selective laser sintering (SLS) because it allows the creation of robust and functional parts, moreover compared to traditional FDM or SLA is the possibility of 3D printing without the need to create supports.

The SLS process uses a laser that melts a powder, which in turn solidifies on the previous layer. In fact, the unsintered powder inside the printing chamber acts as a support for the sintered part.

It is therefore possible to create geometrically complex and reciprocally moving parts in a single printing process. The parts made are free of delamination and have the advantage of being isotropic, that is, they have the same mechanical response when stressed along different directions.

But Who Really is NXT SPEED?

A REAL manufacturer of CNC and 3D parts based in Italy.

NXT SPEEDis not just a group of specialists in traditional mechanics based on the law of subtraction, we believe in innovation and in what the future will be.

Driven by the desire to overcome the production constraints imposed by traditional technologies, we have integrated the use of additive technologies into our company offer.

 

Such as?

We have created a unique team, which has the desire and tenacity to keep up with the new needs of the markets and consumers.

Using state-of-the-art machinery, we apply our knowledge and skills in the field of additive manufacturing to support designers and technicians from all sectors in the design, optimization and production of prototypes and finished products.

Here’s what we do!

Before physically making the required components, we take care of the 3D design that allows us to create completely custom and customized objects on the customer’s request.

We turn to companies that need to make small and medium production batches, but also to individuals with the most varied requests…

Through FDM technology, but also through resin printers with stereolithographic technology (SLA), we create aesthetic and functional prototypes, but also functional pieces suitable for various uses.

All this through a direct and constant contact with the customer who is followed to identify the most suitable technology and material for the development of the projects, supporting him from prototyping to the realization of the final components.

We are professionals with specific training on additive manufacturing techniques and processes, aimed at optimizing your products.

FDM 3D Printing, What is it Really?

By Uncategorized

3D printing, also called additive manufacturing, is nothing more than a process useful for creating three-dimensional objects without any constructive constraints starting from a digital file called an STL file.

The realization of an object thanks to 3D printing takes place through the use of additive processes as the object is created by arranging overlapping layers of material until the final completion.

Each of these layers can be seen as a horizontal cross-section of the object

3D printing allows you to produce complex shapes using less material than traditional manufacturing methods, as there is no waste as was the case with subtractive manufacturing.

 

What are the advantages of printers?

  • They reduce the time to market that is the time that passes between the phase of planning of the object
  • They make it possible to produce extremely complex geometries that are difficult to achieve with traditional production systems
  • On demand production without wasting material
  • Realization of lighter and at the same time performing parts
  • Customization on request, almost without constraints

How does it work?

The principle of operation of a 3D printer is similar to that of inkjet printers, or almost, and consists of three phases:

  • design
  • press
  • post-production

First of all it is necessary to create a 3D model using special programs, thus obtaining a three-dimensional file which will then be “sent” to the printer…

… Then the printer will create a model by transforming a 3D CAD drawing into many two-dimensional and transversal layers by depositing layers of filament.

One layer at a time, from bottom to top, the printer deposits filaments (so-called layers) by repeatedly printing on the same area with a method known as fused deposition modelling.

In English this technique is called FDM, Fused deposition modelling or FFF Fused Filament Fabrication.

 

The material used in 3D printing

The material used for 3D printing is commonly and trivially defined plastic, but there are many types of plastic materials.

3D printers specifically use thermoplastic polymers, which are plastic materials that melt when heated and become solid when cooled.

Thanks to continuous research and the presence of increasingly professional materials, it is now possible to find molded parts in FDM and destined for final use in the production equipment of many automotive plants and even in airplanes.

We at NXT SPEED are always looking for new materials, and we study their textures and characteristics to satisfy the requests of our customers…. run to see the FDM materials section on our site!
