When it comes to new technologies, no field is more exciting than 3D printing. It seems that there is no end to the things you can create with a 3D printer: models and prototypes, human fabric, even food is something few imagined but until this point has arrived). And it seems that almost every month there are a lot of new 3D printers to choose from, and every manufacturer claims that their product is the best 3D printer on the market. This is why choosing a 3d printer complicates many people as there is a lot of variety in the market and few reliable reviews that can help you make an accepted purchase decision. In this guide to buy a 3D printer, we will try to help you as much as we can so that you have the right knowledge to know which 3d printer to buy.
However, before you go and look for a new 3D printer, there are some specifications that you should pay attention to before making any purchasing decisions
Key Specifications for Buying a 3D Printer
Type of 3D printers:
The techniques most used today, depending on the technology they use, are: SLA, SLS, FDM and Printing by Injection.
3D Printing is, undoubtedly, one of the trends in the technology sector. So much that not only is restricted to companies, whatever their size, but many individuals have also climbed the cart and already have their own 3D printers at home. But, are all printers the same? The truth is no, and there are different types of technologies on which 3D Printing is based. Depending on the technology they use, you can differentiate between these types of 3D Printing:
- Printing by Stereo lithography (SLA).
- Laser Selective Sinter Printing (SLS).
- Printing by Injection.
- Printing by deposition of molten material (FDM).
Although they are all different from each other, they have one feature in common: that the object is printed layer by layer, always starting with the bottom and ending with the upper one, following the model of .CAD file that has been created in a way on your computer.
The resolution of your unit will determine the quality and detail of your print. Typically, lower-end units can only print with lower resolution, approximately the 400- micron range. The high-end units will be as low as 100 microns and can have more than 1 extruder, which will also help with print accuracy.
The print bed size of your unit will determine the maximum size project you can create on it. 5 x 5 x 5 is a fairly common size for most desktop units. In addition, inexpensive printers usually come with unheated printing beds, which can limit the types of materials with which you can print. This is due to the fact that the plastic that cools quickly contracts. If it shrinks unevenly in certain places, deformation will occur. A warmed print bed will prevent this, allowing the final product to be maintained at the proper temperature throughout the print and allow it to contract more evenly as it cools.
Another consideration to consider is the printing process. Best 3D printers use a variety of different methods to build and place the finished product. By far the most popular are fused deposition modeling units, due to their cleanliness, ease of use and cost-effective design.
Finally, 3D printers can use a variety of different plastic materials. The most common types are ABS or PLA. There are pros and cons for each type, so it boils down to user preference. If you are looking for a 3D printer with the aim of being multifunctional with switchable nozzles - this will allow you to be compatible with other materials and other types of plastic polymers.
Looking for a 3D printer assembled or built to your liking?
This will depend on your preference for learning; You can buy a 3d printer already armed from the factory or buy one that can arm you like you want, as in the case of a computer armed by you with your own pieces. The advantages of building your own 3d printer are numerous. If you decide to build your own 3d printer you will learn a lot about it and get started. The advantage of this is that if something happens to the team you will know how to fix it yourself, which is not a rare thing to happen to you.
Even a simple task like cleaning a blocked hot end can seem overwhelming to someone who has never seen an unarmed 3D printer. Self-built 3d printers tend to be cheaper than those that come pre-assembled from the factory. Some of the best 3D printers are assembled by the same customer. The only real drawback of building your own 3d printer is the time it takes to do it. It can be very difficult to do and require a lot of patience. Many self-builders proclaim how rewarding they are and how much they learn from it. Of course, it is entirely because of their own strengths and weaknesses.Regardless of which 3D printer you choose, you should make sure that you are buying quality equipment depending on reviews of 3d printer. Even the highest quality 3d printer on the market will have difficulties when feeding with poor quality plastic. If you find your printer jams frequently or produces poor print results, it's time to look for a new machine to get the job done. Reviews of 3d printer
