How the 3D printer works
3D printers are machines capable of making objects in three dimensions , using special software and systems that create real physical structures through a series of overlapping layers . Depending on the model they can use different types of materials for the filament of 3D printing, among which the most common are plastic (ABS or PLA), metals (aluminum, steel or cobalt), ceramics, paper and organic materials. biological. Once the project to be created with the software has been created, the device starts working, with the nozzle moving through a three-axis system and dispensing the filament after heating the material, until the object is finished by overlapping all the layers.
Types of 3D printers: which printing technology to choose?
The 3D printer market is now very large, with products that are more accessible than in the past and very different from each other. There are different printing technologies: in this buying guide we focus on FDM / FFF and SLA 3D printers , and mostly intended for non-professional use. Let’s see together what these acronyms mean:
- FDM : stands for Fused Deposition Manufacturing and is the most widespread 3D printing technology. A plastic filament is melted and extruded so that it can be used for the construction of the print layers;
- FFF : stands for Fused Filament Fabrication and is practically identical to FDM technology. The difference between the two is the origin of the patent, therefore purely of a historical nature;
- SLA : is the 3D printing obtained by stereolithography . The starting material is liquid resin, which is solidified using light. More precise in the creation of small details, it is particularly suitable for printing miniatures and very small details.
So how to choose the best 3D printer for engineers among these printing technologies? We will then explore the aspects to take into account when buying a 3D printer.
Let’s say, to keep it simple, it mostly depends on what you want to print :
- To make PLA models for hobby purposes you can choose an economical FDM ;
- If you want to print accessories in technical material (such as nylon, ABS, polycarbonate, etc…) a semi-professional FDM is more suitable ;
- To build miniatures or objects with a high level of detail we recommend that you buy an SLA 3D printer and focus on professional models.
The technical specifications to take into account to choose the best 3D printer
As always, when it comes to choosing a technological product, the technical specifications are a valid guide to follow in order to orient yourself in the choice. Let’s see together how to read the technical specifications of 3D printers to make a conscious purchase that does not disappoint us:
- Work area : this value represents the print size allowed by the 3D printer, expressed in 3 values corresponding to the 3 dimensions X, Y and Z. Usually the economic printers have a print size of 200x200x200 mm, the larger the print area will be the higher the price of the 3D printer.
- Types of printable materials : Always pay attention to the printable materials declared by the manufacturer. To know the printing performance of your new 3D printer with different materials, it is also useful to always read user reviews.
- Extruder : always evaluates the number of extruders (more extruders = higher speed and printable colors at the same time), the diameter of the extruder and of the filament. The smaller the diameter of the extruder, the higher the printing precision.
- Horizontal / vertical resolution and level resolution : these parameters indicate the deviation in terms of printing accuracy . The lower the declared value, the higher the accuracy of your 3D printer.
- Allowed software and file formats : also in this case, your habits / knowledge define the choice. Always evaluate compatible software and file formats to reflect your 3D modeling habits or knowledge in this area.
- 3D printer assembly and initial setup : prefer pre-assembled and self-leveling models if you are a beginner. Mechanical stability and accurate settings are key factors for accurate and successful 3D printing.
- Safety systems and sensors : if you intend to use your new 3D printer for many hours, even when you will not be present during the printing process, prefer safe models. Accidents are commonplace and can cause annoying and dangerous consequences.
Learn how to use a 3D printer before buying it
On the net you can find dozens of videos and contents to learn how to use 3D printers effectively . Do not underestimate the importance of a conscious use and dedicate time to training, you will get better 3D prints and in total safety.
3D printing machine: types of filaments
On the market we can find different types of filaments for 3D printing :
- PLA : it is a biopolymer derived from corn, economic and eco-sustainable. It is the most common material, the melting temperature is about 180 ° and does not require the use of a heated support base. Perfect for making aesthetic models, it is the best material for printing with cheap 3D printers.
- Composite PLA : it is PLA mixed with other materials such as steel, aluminum, copper, brass, wood or bronze. The purpose of this type of filament is purely aesthetic.
- ABS : it is a non-biodegradable technopolymer suitable for 3D printing of light and robust objects. This material gives off toxic fumes during the printing process, so it is recommended to use it with closed 3D printers.
- PET : polyethylene terephthalate is a strong and flexible thermoplastic resin. It is often used in the making of food containers and bottles.
- Polycarbonate : it is a material with high tensile and flexural strength. Perfect for industrial use and the production of objects resistant to mechanical stress (e.g. components for FPV drones).
