Introduction

3D printing is an evolving technology that is revolutionizing the way objects of all shapes and sizes are made. Simply put, 3D printing is an additive manufacturing process that enables the creation of three-dimensional objects layer by layer. This technology is finding application in a wide range of fields, including design, engineering, medicine, fashion and architecture.

Definition of 3D printing

3D printing is a technology for creating three-dimensional objects from a digital file. The 3D printing process is based on the deposition of a layer of material on a work surface, which is then solidified through the use of an energy source such as a laser or UV lamp. Next, another layer of material is added on top of the first, and so on, until the object is complete.

Brief history of 3D printing

3D printing technology was developed during the 1980s, but it was mainly used for prototype purposes until the mid-2000s. In recent years, 3D printing technology has undergone a series of improvements and developments that have increased its efficiency and reduced its cost, making it more accessible to a wide range of industries.

The history of 3D printing in a nutshell

  1. 3D printing has its roots in rapid prototyping, a technology developed in the 1980s for producing prototype parts.
  2. In 1986, Charles Hull invented stereolithography, a technology that used light to harden a liquid polymer into a three-dimensional model.
  3. In 1992, 3D printing Fused Deposition Modeling (FDM) was invented by Scott Crump, which involves the deposition of filaments of molten material to create three-dimensional objects.
  4. In the 1990s, 3D printing was mainly used for rapid prototyping.
  5. In 2005, 3D printing company Stratasys introduced PolyJet technology, which uses inkjet printing to create parts with a high-quality finish.
  6. In 2009, Selective Laser Sintering (SLS) 3D printing technology was introduced, which uses lasers to melt a polymer into powder and create parts.
  7. In the 2010s, 3D printing became increasingly affordable and widespread, thanks to cost reductions and increased machine performance.
  8. In 2013, 3D printing company MakerBot introduced its first consumer-grade 3D printer, the Replicator 2.
  9. In 2014, 3D printing company Carbon introduced CLIP (Continuous Liquid Interface Production) technology, which uses light and resin to create parts with a high-quality finish.
  10. In the 2010s, 3D printing was used for a wide range of applications, including the production of aircraft parts, the manufacture of custom medical prosthetics, and the production of customized consumer products.

The story of 3D printing is constantly evolving, and the technology will continue to develop in the future, with the potential to revolutionize industrial production and our way of life even more.

Applications of 3D printing

3D printing has been used in a wide range of applications, including the production of prototypes, the manufacture of spare parts for machinery maintenance, the creation of building and automobile models, the production of customized medical components, and much more. Because of its flexibility and versatility, 3D printing is becoming increasingly important in many industries and is expected to have a significant impact on the way we produce objects in the future.


3D printing technologies

There are several 3D printing technologies available on the market, each of which uses a unique additive manufacturing process. In this chapter, we are going to explore the most common 3D printing technologies and their features.

Stereolithography (SLA)

Stereolithography (SLA) is one of the first 3D printing technologies developed and uses a laser to solidify a photosensitive liquid, typically resin, layer by layer. The resin is deposited on the platform and the laser hardens the parts of the resin where the object is to be created, while the unhardened parts remain liquid. The platform is then lowered one layer and the process is repeated until the object is complete. ALS produces objects with a very smooth surface finish and very precise details, but printing times can be quite long and the resin used is generally expensive.

Selective powder casting (SLS)

Selective powder fusion (SLS) uses a bed of fine powder as the base material and a laser to selectively fuse the powder. The laser melts the powder where the object is to be created, and the process is repeated until the object is complete. Because there is no need for media during the printing process, the SLS can create objects with complex shapes. In addition, SLS allows a wide range of materials to be used, including plastic, metal, and ceramic.

Fused Deposition Modeling (FDM)

Fused Deposition Modeling (FDM) is a 3D printing technology that uses a plastic filament as the base material. The filament is melted in a nozzle that deposits it onto the work surface selectively to create the object layer by layer. FDM is a popular and affordable 3D printing technology, with a wide range of materials available including ABS, PLA, and Nylon.

Digital projection stereolithography (DLP)

Digital projection stereolithography (DLP) is a technology similar to ALS, but instead of using a laser to solidify the resin, it uses a UV light source projected through a digital display. DLP can print at higher speeds than SLA, but the surface finish may be slightly less smooth.

Binder Jetting

Binder jetting uses a bed of powder as the base material and a print head that sprays a binding agent onto the powder particles to create the object. After each layer, the platform is lowered and a new layer of powder is added. The process is repeated until the object is complete. Binder Jetting can create objects with complex shapes and a wide range of materials, including sand, ceramic, and metal.

Multi Jet Fusion (MJF)

Multi Jet Fusion (MJF) uses a print head that sprays a thin, uniform layer of powder onto a work surface. Next, the head sprays a fusing agent onto the powder selectively, which fuses the powder where the object is to be created. After each layer, the platform is lowered and the process is repeated until the object is complete. The MJF can create objects with high definition and excellent mechanical strength.

Electron Beam Melting (EBM)

Electron Beam Melting (EBM) uses an electron beam to selectively melt powdered metal, layer by layer, until the final object is created. EBM can produce high-quality metal objects, but it is an expensive technology and requires a special printing environment.

Digital Light Processing (DLP)

Digital Light Processing (DLP) is similar to ALS and DLP, but uses a digital projector to harden the resin layer by layer. DLP can produce objects with very precise details and reduced printing time compared to SLA.

Laminated Object Manufacturing (LOM)

Laminated Object Manufacturing (LOM) uses a paper or plastic layering process. A sheet of material is cut and glued into layers to create the final object. LOM can create objects with very large dimensions and can use a wide range of materials.

Selective Laser Melting (SLM)

Selective Laser Melting (SLM) uses a laser to selectively melt metal into powder, layer by layer, until the final object is created. SLM can produce high-quality metal objects, but it requires a controlled printing environment and a large amount of energy.

In summary, there are several 3D printing technologies available on the market, each with its own advantages and disadvantages. The choice of technology depends on the specific needs of the project, such as the size of the object, the base material, the required surface finish, and the complexity of the shape.


Materials used in 3D printing

Plastic

Plastic is the most commonly used material in 3D printing. There are many types of plastics used, including acrylonitrile butadiene styrene (ABS), polyethylene terephthalate (PET), polycarbonate (PC), and polylactide (PLA). PLA is a biodegradable material that is easy to print and relatively inexpensive, while ABS and PC are durable and suitable for producing functional objects.

Resin

Resin is a material mainly used in SLA and DLP 3D printers. Resin is composed of liquid monomers that are solidified by exposure to UV light. Resin is used for the production of high-resolution objects, such as jewelry, dental prosthetics and precision parts.

Metal

Metal 3D printing uses metal powders such as aluminum, titanium, stainless steel and cobalt-chrome. The technology used for metal printing is generally expensive and requires a controlled printing environment. However, metal printing can produce objects with high strength and precision that are used in aerospace, medical and automotive fields.

Ceramics

Ceramic 3D printing is used to produce objects such as pottery, decorations and machine parts. Ceramics used for 3D printing are generally mixed with resins to improve the stability of the object during printing. Ceramic printing requires high temperature and accurate finishing.

Other materials

There are other materials used for 3D printing, including wood, plaster, sand, and paper. Wood and paper 3D printing uses the material in the form of powder or paste, which is then solidified. Sand and plaster printing is mainly used in the casting industry to create mold shapes for metal objects.


Preparing the model for 3D printing

This chapter of the guide focuses on the processes of preparing and printing objects. These processes are crucial to achieving high-quality, functional printed objects.

Model preparation

Before printing a 3D object, it is necessary to prepare the model. The model can be created using computer-aided design (CAD) software or 3D modeling software. The model must be exported in a format compatible with the 3D printer, such as STL, OBJ or AMF.

Once the model has been exported, slicing software can be used to prepare the model for 3D printing. The slicing software splits the model into thin layers and generates a G-code file that contains instructions for the 3D printer on how to print each layer.

3D printer settings

3D printer settings are important to achieve high-quality printing. Settings include print temperature, print speed, print altitude, and many other variables. These settings may vary depending on the material used and the type of 3D printer.

Most 3D printers allow you to adjust the settings via a built-in LCD display or via printer control software. In addition, you can download predefined printing profiles from the manufacturer or from online 3D printing communities.

Controlling print quality

Once 3D printing has begun, it is important to monitor the quality of the print. There are several factors that can affect print quality, such as print temperature, print speed, 3D printer accuracy, and object geometry.

A number of tools can be used to monitor print quality, such as 3D printer calibration, print bed leveling verification, filament diameter verification, printer temperature verification, and visual inspection of the printed object.

Finishing the printed object

Once the object has been printed, it is necessary to remove it from the printing platform and remove any media or waste material. Tools such as scrapers, pliers, cutters, and other metal and plastic processing tools can be used in this process.

Next, the object can be sanded with sandpaper or an abrasive sponge to remove any irregularities or roughness. Alternatively, electronic sanding tools, such as electric sanders or rotary tools, can be used.

For some specific parts of the object, such as holes or cavities, it may be necessary to perform a more thorough finishing operation, using tools such as drills, files, or cutters. In this way, holes or cavities of precise and uniform size can be obtained.

If the object was molded in a flexible material, such as TPU (thermoplastic polyurethane), it may be necessary to perform a post-processing operation, such as steaming the object, to reduce the amount of excess material and improve the flexibility of the object.

In general, the finish of the molded object is important to ensure its quality and functionality. A good finish can improve the appearance of the object and reduce the risk of any breakage or deformation.

Post-production

After finishing printing and finishing the object, it may be necessary to perform some post-production tasks, such as checking the object’s dimensions, checking functionality, checking strength, and repairing any damaged or deformed parts.

To check the dimensions of the object, you can use a caliper or other precision measuring instrument. To check the functionality, you can perform strength or flexibility tests of the object. To check the strength of the object, a load test can be performed by gradually applying a load to the object and checking when rupture or permanent deformation occurs.

If the object has damaged or deformed parts, a repair can be performed using adhesives or cold welding, depending on the material used for 3D printing.

Future developments

3D printing is an ever-evolving technology, and there are many future developments that could improve the quality, speed, and convenience of 3D printing. Some developments include color 3D printing, 3D printing with composite materials, 3D printing of human organs, 3D printing of food, and 3D printing of houses.

In addition, there are many research projects that seek to improve the sustainability of 3D printing by reducing energy and material consumption and increasing the recyclability of the materials used.

In summary, preparing and printing 3D objects requires knowledge of numerous processes and technologies. However, with experience and the use of monitoring and finishing tools, printed objects of high quality and functionality can be achieved. In addition, the evolution of 3D printing technology offers many opportunities for the future, both from the perspective of practical applications and sustainability.


The 3D Printer

Types of 3D printers

There are several types of 3D printers, but the most common ones are:

  • Fused Filament Fabrication (FFF): uses a thermoplastic filament that is melted and deposited layer by layer until the model is created.
  • Stereolithography (SLA): uses a photosensitive liquid that is solidified with a laser beam.
  • Selective Laser Sintering (SLS): uses a powdered material that is solidified with a laser beam.
  • Digital Light Processing (DLP): similar to ALS, but uses a different light source.
  • Binder Jetting (BJ): uses a powder material and a liquid adhesive to create the pattern.

Components of a 3D printer

3D printers are composed of various components, including:

  • Print plate: the surface on which the model is printed.
  • Printhead: the component that deposits material on the printing plate.
  • Motor: controls the movement of the printing plate and the printing head.
  • Electronic board: controls all the movements of the printer.
  • Feeder: supplies power to the printer.
  • Display: shows information about the printer and the printing process.

How to choose the right printer for your needs

When choosing a 3D printer, there are several considerations to take into account, including:

  • Cost: The price of 3D printers ranges from a few hundred euros for entry-level printers to thousands of euros for more advanced printers.
  • Size: The size of the printing plate determines the maximum size of the model that can be created.
  • Materials supported: 3D printers can support different types of materials, but not all of them support all types of materials. It is important to choose a printer that supports the right material for the project you want to create.
  • Accuracy: The accuracy of 3D printing depends on the resolution of the printer and the settings used.
  • Printing speed: 3D printers can have different print speeds depending on the type of technology used and the print settings.

3D printing process

In this chapter we address the 3D printing process and how to make a design from the preparation stage to printing to finishing the model. Here is a summary of the points covered in this chapter:

  1. Preparation of the printer and material: Before starting printing, it is necessary to prepare the 3D printer and the printing material. Preparation of the printer may include cleaning the printing chamber and calibrating the printer axis movements. In addition, you need to load the printing material into the printer, set the temperature and prepare the print base.
  2. Setting the printing parameters: The next step is to set the printing parameters on the 3D printer. These parameters may vary depending on the printing technology and the type of material used. Some of the parameters to be set include print speed, material temperature, layer height and fill.
  3. Printing launch and quality control: Once the parameters have been set, printing can be started. During printing, it is important to monitor the process and check the quality of the model. There are several factors that can affect the quality of printing, such as the temperature of the environment, the quality of the material, and the setting of the printing parameters. If problems occur during printing, you can make changes to the printing parameters or take action on the printer to solve them.
  4. Removal of printing media: Once printing is complete, you need to remove the model from the printing base and remove the printing stand. The printing stand is an additional structure that is used to support the salient parts of the model during printing and must be removed carefully to avoid damage to the model.
  5. Finishing and polishing the model: After removing the print support, finishing of the model can be done. Finishing may include removing surface irregularities, polishing and sanding the model. Depending on the type of material used, you may need to use specific tools or chemicals to achieve the desired finish.
  6. Possible painting and finishing options: Finally, you can proceed with painting and finishing the model. This step is optional, but it can help improve the appearance of the model. You can use spray paint or brushes to paint the model and apply other details such as stickers, stickers, or other finishing touches.
