Finer Versions for the Best 3D Printing Options Now
If you are a novice, convinced from the start or a professional in the sector, the choice of a 3D printer always remains a sensitive question as the competition is great and the number of parameters to be taken into account important. To enlighten you in your choices, 3Dnatives went to meet three very different profiles: a maker, and a provider in 3D printing.
What are the criteria to take into account when buying a printer? Is it better to favor the printing volume, the heating plate or the number of extruders? Should you go on an open-source model or a proprietary 3D printer? Below, find the answers from our 3 experts. You can go for the 3d store online there.
The function of the extruder is to push or pull the filament of material throughout the printing process.
A single extruder 3D printer model will allow you to print one color or one material at a time. While a double extruder model will allow you to make more complex objects. Please note, the dual extruder 3D printer is more difficult to configure.
Also called construction speed, this is the speed at which the 3D printer deposits the filament of material on the printing plate. It is indicated in mm / second.
Given for information by the manufacturers, the printing speed depends on the resolution chosen. The more precisely the object is printed, the longer the printing time. Find your best options there with the 3D printers for sale.
Also called precision or print quality, the resolution takes into account the thickness of each layer of filament deposited, in mm (vertical precision). Added to this is the horizontal precision with the precision of the positioning of its print head and its plate (in the case of a 3D printer with mobile plate).
3D printer accessories
A 3D printer cannot function without certain accessories such as modeling and slicing software, as well as of course the material used to create the object. With the 3D scanners for sale this is important.
To be able to print, the part you want to obtain must first be created in 3D modeling software. There are two printing possibilities:
- Opt for software allowing you to model your own creations, and therefore train you in its use.
- Opt for models of 3D objects already created, some of which are even available for free.
- Then there is the essential software for slicing and controlling the 3D printer called Slicer or slicer in French. It is he who interprets the project in 3D and prepares the 3D printing, therefore by slices, depending on the printing speed, the type of material used, the amount of material, etc.
There are different materials usable in 3D printing, each with their specificities:
- One of the most common is PLA, consisting of corn starch or beet, easy to use and biodegradable.
- There is also ABS, a thermoplastic polymer, also used by 3D pens. Resistant to shocks and temperature changes, it requires a 3D printer with a heating plate and a closed printing chamber.
- In addition, there are materials such as PET and PETG, polyester plastics which allow food contact and offer excellent impact resistance.
- TPU, known for its elasticity, but which dreads high temperatures and chemicals.
- Nylon, particularly resistant to impact and friction orPC, a transparent polycarbonate extremely solid and resistant to heat, but sensitive to UV.
