If we had only thought a few years ago of a technology capable of making our thoughts concrete almost completely simultaneously, most likely it would have been an idea with a bit of a science fiction flavor, a point at which technology would never have reached. , or he could never get close.
Well, today we can say we were wrong, since 3D printers are a fairly widespread reality today; In fact, thanks to continuous research in the field and the speed at which technological advances are achieved today, it has been possible after a very short time from the first release on the market of these small jewels a reduction in prices and costs relating to them, allowing anyone to buy a 3D printer.
Best Budget 3d Printer
The future is here: an inexpensive 3D printer , a modern evolution of traditional printers, is now within reach.
In fact, spending a few hundred euros, today this type of technology is accessible to everyone.
We are offered a wide range of low cost printers that allow us to make small objects at low cost, choosing materials and shapes.
To know which is the most suitable 3D printer to get started , a few simple information is enough.
Of course, a small initial investment is needed because we are talking about a real revolution in printing and its mechanism, but with little it will be possible for anyone to own a 3D printer.

Which 3D printers to buy?
If it comes to buying 3D printers for home use , most likely you will have to pay attention to characteristics different from those observed for a purchase for industrial purposes. In fact, absolute precision will not be an aspect to be referred to with extreme importance, since every 3D printer has a very high level of precision, and a rigid and almost perfect request can be expressed by a client in the medical field, almost never certainly by a private individual. .
Rather, it is necessary to deal with features and problems from a more practical point of view, for example size , weight and footprint . Here are some models of 3D printers perfect for use at home, and with excellent features for such use.
Where should you buy them?
Nowadays we have the convenience of being able to carry out most of our actions through the aid of a computer (if we think about it, the same 3D printing can be categorized with the previous statement); one of the greatest facilities offered by this service is that of being able to make purchases directly online.
This solution leads to two benefits: the first is not having to go directly and physically to the store, which can be a great effort both from the point of view of distances and organization for some people, the second positive aspect instead of buying online is that it is more convenient : online it is in fact possible to find many offers at any time of the year, and thanks to sites that offer these offers, it is possible to save a lot.
One of the first sites known for its effectiveness, its reliability but also its prices is Amazon , so it is worth visiting its interface to look for the most suitable 3D printer model for sale at an affordable price.
3D printing software
The programs used to give commands to 3D file printers are obviously 3D modeling software . Among the main ones it is possible to recognize the CAD software , which are used to create the actual drawing.
Once this is done, you need to switch to the CAM software , which basically gives directions to the printer and tells it precisely how it should move.
Keep in mind that almost all 3D printers support the Standard Tessellation Language ( .STL) format .
What are the prices of 3d printers
Thanks to their ever increasing fame and usefulness, it is possible to find various types of 3D printers on the market which correspond to different prices . Obviously it must always be taken into consideration that in any case we are not talking about toys, and therefore this type of product can never be found on the market at a bargain price (we are talking for example, of 50 dollars).
We can therefore divide the 3D printers for sale based on their price, into three main categories. But first it is necessary to make a further clarification, and that is that the price of the same model of 3D printer could change if you decide to buy it as a kit to assemble (with a cheaper price then), or already assembled (opting for a more expensive cost ). high).
The most expensive models are for example the professional FDMs , (Fused Deposition Model, which we talked about previously) among which we can find the Makerbot brand , which offers its best models (including the Z18) at a price that is between 6000 and 7000 dollars. These machines in addition to presenting very high performance in terms of production of 3D elements, also boast a robust and durable metal structure that increases its value.
For an average cost range, on the other hand, we can find the Sharebot and Kentstrapper brands , both Italian. For their models, the price ranges between 1500 and 3000 dollars. For the models to be assembled offered by these Italian companies, the price can go down to around 1000 dollars.
The cheap 3D printers on the market are around 200-500 dollars. At this price obviously we can find 3D printers for mainly sporadic and domestic use, but always with a fairly high quality of the finished product.
Obviously it is also possible to think of a further alternative, namely that of resorting to
Cheap 3D printer: how 3D printing works
If you are new to the world of 3d printing and need the basics, you can start here.
The process is not very different from what we use to print a document with the traditional printer we have at home.
It is in fact sufficient to create the model of the object that you want to create: the project will then be sent to the printer which will build it in front of our eyes, layer by layer.
The object to be printed can be designed with a 3D-modeling software (such as Autocad ) or, alternatively, a 3D scan of an existing object or, even more simply, a “preset” model downloaded from the Internet is fine. .
Where’s the catch? There is not!
The printer works because the document that is sent to print contains all the details of the final product: length, depth and materials to be used.
The printer software, in fact, is able to “break down” the model into several smaller layers that are printed one at a time and then stacked one on top of the other.
The technology of an inexpensive 3D printer
There are different types of printing technologies to print in three dimensions, such as material extrusion ( FDM ), tank curing ( SLA and DLP ), Powder Bed Fusion ( SLS, DMLS & SLM ) Material Jetting ( MJ ) .
The economic 3D printers , as well as professional 3D printers are of two different types:
- FFM (fused filament manufacturing)
- SLA (stereo lithography).
The in FFM printers operate with a technology based on a nozzle that deposits, layer after layer, a molten polymer, up to the final piece.
In other words: a plastic filament is dissolved in a moving print head which, piece by piece, creates the desired object.
The laser sintering technique (SLA) instead uses a laser to synthesize powdered plastic material which is then transformed into a solid structure.
In other words: a very thin layer of powder is spread on the work platform so that, layer by layer, the laser solidifies the powder, finally arriving at the final result.
FFM printers are generally cheaper (and also easier to use).
However, some SLA models are becoming more and more affordable.
What are the Materials for 3D Printing?
As we have just seen, most of the low cost 3D printers are filament printers.
The printing mechanism rotates around the thin plastic thread which, once melted, descends to the surface of the object.
It is important to know that the filaments that are used are made up of different materials.
The most common plastics are ABS and PLA.
L ‘ ABS , so to speak, is the same plastic that is used for the Lego blocks. It is resistant, robust but also very light.
A valid alternative for more eco-friendly 3D printers is PLA (which is nothing more than the bioplastic with which biodegradable disposable tableware is produced).
Another increasingly used material is polypropylene , characterized by high ductility and excellent thermal and abrasion resistance.
In practice, it can be used to create truly indestructible objects (as well as being a lower cost material due to its high technical properties).
Many of these materials are available in a wide range of colors.
The filaments, on the other hand, are available in two sizes: 1.75 mm and 3 mm.
SLA printers have fewer options than their FFM counterparts – they don’t use plastics but usually resins to produce rigid, flexible, or rubber models.
The print volume
Print volume is another important specification for choosing an affordable 3d printer .
A larger volume will allow us to reproduce larger objects.
The limit for the print volume is defined by the size of the print bed and how far the printer can move the print head.
It is usually measured in cubic inches , which determines the maximum 3D print size the device can create.
Let’s take an example: If a printer has a print volume of 223 inches (6.2 x 6 x 6 inches), it can print objects that are up to 6 inches (15 cm) high in height, width and depth.
If we need to print a model of a historic building or similar products, it is advisable to opt for a less economical printer that allows us to complete any project without problems.
If, on the other hand, our goal is to create pieces of art, figurines, small pieces of costume jewelery, practically any cheap 3D printer can do for us.
The thickness of the layers
Another specification to look out for is the thickness of the layers the machine can reproduce.
Let’s not forget, in fact, that 3d printers create objects through a layered system.
The thickness of the latter indicates the maximum print resolution.
Clearly, the thinner the layers, the cleaner the printed object will be, giving the perception of a single, well-defined layer.
But be careful: a thinner layer will take longer to complete the print.
Therefore the choice of thickness is not a simple choice.
In general, it is advisable that the thickness of the layer / layer does not exceed half the width of the nozzle: for example with a 0.4 mm nozzle the maximum thickness of the layer for a good print is 0.2 mm;
3D printers can be very slow.
After having sent our project to print, you need to arm yourself with a healthy dose of patience and … wait.
A model that measures around 10cm usually takes between 6 and 12 hours to print.
As we have just seen, 3D printing works in layers:
The thicker the layers, the faster the printing will be… but at the expense of the quality of the object produced.
This is why in choosing a good cheap 3D printer you have to be careful to find a good compromise between speed and print quality.
Without being guided by the haste that is, even in this case, a bad adviser.
Of course, for a newcomer to the world of 3D printing, getting through all this information and the exorbitant number of cheap and professional 3D printers on the market can be difficult.
