High accuracy 3d printer

Best High Resolution 3D Printers 2022: Complete Buyer's Guide

Resolution is a much-misunderstood aspect of accurate 3D printing, and there are many important factors that affect print quality beyond just layer height. This article recommends the best high-resolution 3D printers, explains the factors making up a high-resolution 3D printer, and the benefits and drawbacks.

Typically within 3D printing resolutions, the Z-axis resolution, or Z-resolution, is most discussed. This is the vertical resolution and means the minimum layer height or thickness possible for a 3D printer.

Small layers mean better resolution, and better surface quality parts with smoother surfaces and crisper edges.

Therefore, having a high-quality 3D printer that can print with small layer heights can be a great advantage. However, this is not the only factor that affects print quality, with a host of others affecting whether a high-resolution 3D printer actually prints accurate, smooth parts.

Resolution in 3D printing: X, Y and Z resolution

Z-resolution corresponds to the layer height of a printed part. However, the X and Y-planes are also very important in a high resolution 3D printer.

The X and Y axes control the 2D parts of the print: those within each 2D layer. The Z then adds multiple layers, responsible for height – the third dimension. Though they are all axes, the XY and Z axes are controlled by two separate systems, with some FDM printers having far more accurate Z-resolutions than XY.

The X and Y resolutions are the smallest movements the printer’s print head (the projector, extruder or laser, depending on technology) can make within a layer – horizontally.

Different 3D printing technologies are capable of better resolutions than others. For example, SLA 3D printers are more accurate than FDM 3D printers, even though their Z-resolutions can look similar on paper. This is mostly down to the better XY resolutions resin 3D printers can print with, leading to smoother surface areas, with the best resin printers able to print parts with barely noticeable layer lines.

However, other factors can also significantly affect print quality.

Other factors that affect print quality

• Nozzle size: smaller nozzles on FDM 3D printer extruders can print more intricate and precise details. Standard nozzles are typically 0.4mm, though you can get far smaller 0.1 or 0.2mm nozzles for small and accurate details. They also work better for printing supports and overhangs.
• Stability of frame & vibrations: a sturdy, heavy metal frame that anchors the printer and print bed to the ground is less affected by vibrations and other extraneous factors that can affect print quality.
• Material: different materials are more accurate and precise than others, or are easier to print successfully than others.
• Technology: for example, SLA printers are more accurate than FDM, and PolyJet offers some of the best precision in 3D printing.
• Slicer and printer settings: your 3D slicer settings will make all the difference in print quality, and even the most high resolution 3D printers will print poor quality models if not optimized.

When do high quality 3D printers make the most difference?

If you plan on 3D printing a very basic structure like a cube, whether you use a high quality 3D printer, or use large or small layers, will make no difference. In fact, using small layer heights will just make the exact same print take far longer.

For these very basic models with few intricate parts or details, a standard cheap 3D printer will work almost as well as an industrial, high-resolution 3D printer that costs 20x the price.

However, high-quality precise 3D printers make a significant difference in more complex parts that have diagonal or arched lines or sides, or have embossing and engravings.

Especially in curved or diagonal parts, the lower the layer height and more accurate the printer, the less stepped these features will appear, and the smoother they will look, even up close.Very high-resolution 3D printers such as resin printers are commonly used to 3D print jewelry molds, such as this 3D printed ring.

Moreover, if you are printing a small part, for example 3D printing a miniature or tabletop model, using an accurate printer with very small layer heights can be worth it, as even if it takes several times as long this still won’t take more than an hour.

The best high-resolution 3D printers

Now we have illustrated the components that make up a high-quality 3D printer, here are some recommendations.

High resolution and quality here are relative, meaning that we have chosen those in each price range that excel – a $200 3D printer cannot compete with an industrial 3D printer costing $20,000, but it may be the best in its price range.

Ender 3 V2 – accurate 3D printer for under $300

• Price: $279 – Available on Creality Official Store here / Available on Amazon here
• Build volume: 220 x 220 x 250 mm
• Type of 3D printer: FDM 3D printer & DIY 3D printer
• Minimum layer height: 0.1mm

Just as the original Ender 3 was starting to get long in the tooth, Creality swooped in with the Ender 3 V2. A well-thought-out printer, the Ender 3 V2 remedies many of the misgivings of its predecessor while still keeping the asking price affordable to even the most budget-restrained makers.  

The belt tensioners, 4.2.2 32-bit mainboard, and silent stepper motor drivers do a lot to present what feels like a far more modern printer compared to the Ender 3.

In the context of low-cost high-resolution 3D printer performance, the Ender 3 V2 spec sheet doesn’t exactly wow, with a middling 100-micron layer resolution. But, don’t be fooled; high-resolution printing is defined by more resolution alone.

In action, the Ender 3 V2 assembles with a level of accuracy that feels inordinately good for a low-cost FDM printer. With few visible, warping, or layering issues with an excellent overall quality for larger parts and respectable results for smaller, detailed parts. And, coupled with that is a suitably large build volume – 220 x 220 x 250 mm to be exact – for larger projects and even small-scale batch printing.

For the price, you additionally get to play with a decent range of materials – PLA, ABS, PETG, TPU. The only caveat is you’ll need to stick to more straightforward prints, those relatively free of intricate embossing, minute detail, tight arches, and the like.

In our experience, the Ender 3 V2 shines best when used to create household items such as plant pots or, say, vases, figurines, toys, accessories, and similar items. We’d wager it also packs in enough printing aptitude for a modest business selling non-geometrically complex products.

Be warned; the Ender 3 V2 is very much a hobby kit printer, requiring its fair share of tinkering to perform at its best. Curious beginners up for a challenge and seasoned makers should find this a gratifying part of the printing process, but green newcomers may prefer an option a little lighter on the ‘hands-on’ aspects.

Anycubic Photon Mono 4K

• Price: $299 – Available at Anycubic Official Store here / Available on Amazon here
• Build volume: 132 x 80 x 165 mm
• Type of 3D printer: LCD 3D printer
• Z-axis accuracy: 0.00125 mm, XY Resolution: 0.035 mm

Yet another iterative upgrade to a respected family of resin printers, the Anycubic Photon Mono 4K is another impressive option for those high-res 3D printer heads out there. It’s no understatement to count the Anycubic Photon Mono 4K among the top cheap high-resolution 3D printers out there.

Under the hood, the Anycubic Photon Mono 4K sports, you guessed it, a 4K LCD panel capable of a pixel resolution of 35 microns, a 15-micron improvement on its predecessor. In layman’s terms, this equates to a smooth finish and fine detail in every print, both immediately apparent to the naked eye.

Imperfections are near indistinguishable, and, dare we say it; the results are as close to perfection as we’ve seen in this price range in the overwhelming majority of prints. The Anycubic Photon Mono 4K also nips through prints with a more-than-respectable sub 2 second layer cure time.

For us, the printer brims with hobby potential. We’d be hard-pressed to pinpoint an application where it doesn’t impress. That said, the Anycubic Photon Mono 4K comes into its element with 3D models and similar display items thanks to its propensity for carving out detailed features.

Much like other resin printers, the Anycubic Photon Mono 4K comes with its fair share of mess and requires strict adherence to a regular cleaning regimen. The absence of a resume function and an occasionally temperamental native slicer feel like unfortunate oversights. But, these are minor gripes for an otherwise excellent low-priced, small form factor resin printer.

Elegoo Mars 3 – Best Cost-Effective Resin Pick

• Price: $349 – Available at Elegoo store here / Available on Amazon here
• Build volume: 143 x 90 x 165 mm
• Type of 3D printer: LCD 3D printer
• Z-axis accuracy: 0. 00125 mm, XY Resolution: 0.035 mm

The Elegoo Mars is back and arguably better than ever, with a new numeral slapped on for good measure. Fast, beautifully detailed, compact, and cost-effective, the Elegoo Mars 3 also sports the specs we like to see in high-resolution-geared resin printers, namely a 6.6-inch 4K Ultra Monochrome LCD and a razor-thin 35-micron resolution.

Marketing and technical blather aside, Elegoo Mars 3 delivers impressively detailed results with clean edges and on-point accuracy suitable for even the most demanding resin projects. A larger build volume than the Mars 2 Pro, tallying up to 143 x 90 x 165 mm, also lends itself to larger prints while keeping up those minute features and finer details.

We’re particularly impressed with how well the printer fares when tackling figurines, toys, and models, even what we deem large ones for a resin printer. Best of all, the Elegoo Mars 3 sticks to the Mars tradition of no-nonsense printers that perform to the same high standard day-in, day-out. In other words, a workhorse.

Despite some reservations about the flimsy lid and the lack of features like air filtration and Wi-Fi connectivity, we highly recommend the Elegoo Mars 3 for makers, hobbyists, and businesses looking for a cheap high-resolution 3D printer. Note that the Elegoo Mars 3 is tied to the ChiTuBox slicer and won’t work with third-party alternatives.

• XY Resolution: 25 microns

The leading prosumer resin 3D printing company, Formlabs printers are now used extensively across the jewelry, dental, medical and hearing aid sectors.

Looking at the numbers underpinning the Formlabs Form 3 – chiefly, a 145 x 145 x 185 mm build volume and 25-micron resolution – isn’t exactly a head-turner. However, Formlabs’ innovative LFS tech is the type of innovation we like to see. The real sophistication lies in just how easy the printer is to use. With the Formlabs Form 3, the onus is on the machine to do its thing, no faffing and no babysitting required.

And, the results follow. Equipped with high-quality resin, the Formlabs Form 3 performs exceptionally to yield beautifully finished and detailed prints suitable for commercial ends. Print failures are all but nonexistent; you’d need to physically shake the machine during a print to trigger anything resembling errors.

You do pay a hefty premium for the pleasure of owning a Formlabs Form 3. However, the expense is quickly recouped in time saved alone by the set-a-task-and-forget nature of the printer, something that could conceivably prove invaluable in a fast-paced commercial environment. For small to medium-sized businesses requiring small-batch failsafe precision models along with prototyping, there’s little out there to rival the Formlabs Form 3.

Overall, for precise 3D printing, the Form 3 is one of the highest resolution and quality 3D printers out there.

• Minimum layer height: 20 microns

Smaller, but every part as technically brilliant as the S5, the Ultimaker S3 is capable of incredible 20-micron layer heights that are so small you’ll struggle to see them. Though this slows down print time by increasing the number of layers in a part, the resulting model will have unmatched quality compared to almost any other FDM printer.

As well as the fantastic precision, the Ultimaker S3 is also a dual extruder 3D printer, allowing for the production of precise, multi-colored or multi-material 3D prints, and as a result is used heavily in creating architectural building model prototypes before building work begins.

• For those interested in architectural model production, view our ranking of the best architecture software.

The printer is easy to use, easy to print with – Ultimaker also own Cura, the most popular 3D slicer – and offers fantastic 20-micron precision with a wide variety of materials compatible, including carbon fiber. Overall, the printer speaks for itself, and proves itself as one of the best high resolution 3D printers in FDM.

Advantages of a High Resolution 3D Printer

• Better quality: high resolution makes for smoother surface finishes, with great details and aesthetics on parts.
• The only way to get fine details: models that have arches and sharp diagonal details can look very jagged in higher layer heights, with low resolution 3D printers unable to adequately print these details.

Disadvantages of an accurate 3D printer

• Perfect settings required: increased precision requires perfect calibration, the perfect temperature settings to avoid imperfections in the filament or resin, and the right heated bed temperature and adhesion on the print bed. Any errors here can create imperfections in the print.
• Much slower: printing with 25-micron layer heights takes four times as long as 100-micron layer heights, as four 25-micron layers equal the height of one 100-micron layer. For large and complex models, prints can take days.
• Higher chance of print failure: the more layers a model has, the more opportunities there are for errors to occur – which could render the part useless.

High-Resolution 3D Printing Technologies

Some 3D printing technologies considered high-resolution include:

FDM – Fused Deposition Modeling

FDM, or Fused Deposition Modeling, is the most popular and common technology used for high-resolution printing. The process involves depositing melted filament in layers on a fixed build platform using a heated extruder to create models. FDM falls on the lower end of the high-res spectrum and is generally favored as a low-cost alternative to more expensive technologies. FDM printers commonly offer resolutions in the 50 to 200 microns range.

Resin (SLA, DLP, LCD)

Photopolymerization, commonly known as resin 3D printing, involves projecting a laser or light source to cure liquid light-sensitive resin into layers. Specific technologies include Stereolithography (SLA), Low Force Stereolithography (LFS), Masked Stereolithography Apparatus (MSLA), and Digital Light Processing (DLP).  Resin printers commonly hit layer resolutions as low as 25 to 35 microns.

MJF – Multi Jet Fusion

Multi-Jet Modeling, or Material Jetting, uses inkjet print heads to jet melted materials layer by layer to create a 3D part or model. Expensive and highly accurate, MJF printers are the reserve of large businesses with deep coffers.

PolyJet – Photopolymer Jetting

Printers that employ PolyJet, or Photopolymer Jetting, rely on layers of photo-sensitive liquid photopolymer resin jetted via print heads then cured thanks to a UV light source to create prints. Much like MJF, PolyJet involves considerable expense, although the printers are generally smaller in size.

High-Resolution 3D Printer FAQs

Are High-Resolution 3D Prints Stronger?

No, the opposite. As a general rule, thicker layers (or a lower resolution) generate tougher results. This is because they minimize the number of contact points between layers. Fewer layers interfacing with one another means a lower likelihood of bond strength issues.

But, print strength relies on many factors, including layer adhesion and height, extruder and bed temperature, material quality and type, and the printing technology employed. A definitive answer is more related to the specific printer than the resolution. A capable device, like any of the best high-resolution 3D printers, produces reliable parts at higher resolutions.

What Is High-Resolution 3D Printing?

The answer varies greatly depending on who you ask. For the sake of simplicity, high-resolution 3D printing is best described as the process of printing parts with higher overall quality – whether that be smoothness, finish quality, detail, or model accuracy – than you’ll typically find in the 3D printing space.

What Can You Do With a High-Resolution 3D Printer?

High-resolution 3D printing suits a vast swathe of applications. In the commercial field, companies favor high-resolution printing in areas such as dentistry, jewelry, biomedicine, and all manner of functional prototyping where precision is critical. In the hobby space, makers turn towards high-resolution printing for projects that require fine detail, such as figurines, modeling, and other decorative pieces.

What Effect Does 3D Print Resolution Have on Speed?

Higher resolutions decrease speed.

Print speed relates to how fast a printer deposes each layer. Since high-resolution printing is synonymous with thinner layers, the print speed is generally slower than lower-res printing. High-resolution 3D printing sacrifices print speed in favor of accuracy. Exact timings depend on the desired resolution, the technologies underpinning the printer in use, such as resin or MJF, and the complexity of the model.

Clarity, Accuracy & Tolerances in 3D Printing

Just because your 3D printer says it has "high resolution" does not mean it will produce accurate or sharp prints.

Understanding the meaning of the terms precision, clarity, and tolerance is a prerequisite for achieving quality 3D printing results, regardless of industry. In this article, we will analyze what these terms mean in the context of 3D printing.

Let's start with some definitions: what is the difference between precision, clarity and tolerance? For each term, we will use a target - a common example for understanding these concepts, helping to visualize them.

Precision determines how close the measured value is to the true value. In the target example, the true value is the bullseye. The closer you are to the bullseye, the more accurate your throw. In the world of 3D printing, the true value is the dimensions of your CAD model. To what extent does a product made on a 3D printer correspond to a digital model?

Clarity corresponds to measurement reproducibility - how consistent are your hits on the target? Clarity only measures this reproducibility. You can always hit the same spot, but it doesn't have to be the bullseye. In 3D printing, this ultimately leads to reliability. Are you sure that you will get the expected results for each model produced by your printer?

In engineering terms, "clarity" is used to measure the reproducibility of results. Applied to materials for 3D printing, “clear” can mean the ability to manufacture complex geometries. For example, Formlabs Gray Pro Resin and Rigid Resin resins have a high "green modulus", or modulus of elasticity, that can successfully print thin and intricate details.

What accuracy is required in this case? This is determined by tolerances , which you define. How much wiggle room do you have based on the purpose of the model? What is the allowable variability in the closeness of the measurements to the exact ones? It depends on the specifics of your project. For example, a component with a dynamic mechanical assembly needs tighter tolerances than a conventional plastic housing.

If you're specifying tolerance, you'll probably need precision as well, so let's assume we're measuring bullseye accuracy. Earlier we called the shots in the picture with the target on the right fuzzy.

But if you have wide tolerances, this may not be a problem. The shots are not as close to each other as they are on the target on the left, but if the acceptable range of sharpness is ±2.5 hoops, then you are not out of range.

As a rule, achieving and maintaining tighter tolerances entails higher production and quality control costs.

There are many factors to consider when thinking about precision and clarity in 3D printing, but it's also important to get your needs right.

For example, a sharp but inaccurate 3D printer may be optimal for some applications. An inexpensive Fused Deposition Modeling (FDM) machine will produce less accurate parts, but for a teacher teaching students 3D printing for the first time, the exact fit of the student's CAD model doesn't matter as much.

But if the printer performs to specifications and delivers the quality expected of it within the tolerances the user is accustomed to, this may be sufficient for successful operation.

Check out our detailed guide comparing FDM vs. SLA 3D printers to see how they differ in terms of print quality, materials, application, workflow, speed, cost, and more.

There are four main factors that affect the accuracy and clarity of a 3D printer:

3D printing is a type of additive manufacturing where models are made layer by layer. Violations can potentially occur in every layer. The layering process affects the level of clarity (or reproducibility) of each layer's accuracy. For example, when printing on an FDM printer, layers are formed using a nozzle, which cannot provide the same accuracy for obtaining complex parts as other 3D printing technologies.

Because layers are extruded, FDM models often show layer lines and inaccuracies around complex features. (Left is an FDM printed part, right is a SLA printed part.)

In stereolithography (SLA) 3D printing, each layer is formed by curing a liquid polymer with a high-precision laser, resulting in more detailed models and achieve high quality on a consistent basis.

Selective Laser Sintering (SLS) also uses a laser to accurately convert nylon powder into lightweight, durable parts.

The specifications of a 3D printer alone do not give an idea of ​​the accuracy of the models produced. One of the common misconceptions about the accuracy of various 3D printing technologies is describing XY resolution as dimensional accuracy.

For digital light processing (DLP) printers, the XY resolution corresponds to the projected pixel size. Many 3D printer systems use this projected pixel size, or XY resolution, as a general measure of accuracy, such as stating that with a projected pixel size of 75 µm, the accuracy of the device is ±75 µm.

Check out our guide to SLA and DLP 3D printing, where we talk about the features of the two processes and how they differ.

But this data does not affect the accuracy of the printed model. There are many other sources of error that affect accuracy, from components and calibration to materials and post-processing. We will consider the last two factors in more detail.

The best way to evaluate a 3D printer is to study the models printed on it.

Accuracy may also vary depending on the media you are printing on and the mechanical properties of those media, which can also affect the likelihood of model warping.

Formlabs Rigid Resin has a high "green modulus", or modulus of elasticity before final polymerization, which allows you to print very thin models with high definition and reliability.

But, again, it all depends on your goals. For example, in dentistry, the accuracy of 3D printed models is critical. But if you're printing a concept model, chances are you just want to get a general idea of ​​the physical product, and accuracy won't be that important.

Margins, mold surfaces, and contact surfaces printed with Formlabs Model Resin are accurate to within ±35 µm of the digital model at over 80% of surface points when printed at 25 µm settings. The overall accuracy across the entire arc is within ±100 µm on 80% of surfaces when printed with settings of 25 or 50 µm.

3D printed models often need to be cured, which in turn often leads to shrinkage. This is normal for any part made using SLA or DLP 3D printing. Depending on the printer, this phenomenon may need to be considered in the design. PreForm, Formlabs' free file preparation software, automatically compensates for this shrinkage, ensuring that the final cured models are the same dimensions as the original CAD model.

How does the final polymerization work? Learn more about the theory behind the process and see efficient ways to successfully finish curing models made with stereolithographic 3D printers.

Producing quality models on a 3D printer requires attention not only to the printer itself, but to the entire production process.

The final result may be affected by the print preparation software, post-processing materials and tools used. In general, integrated systems designed to work together produce more reliable results.

Unlike machining, where parts are progressively improved to tighter tolerances, 3D printing has only one automated manufacturing step. While complex coating adds cost to processes such as CNC milling, creating complex features with 3D printing is essentially free, although the tolerances of a 3D printed model cannot be automatically improved beyond the capabilities of the printer. without resorting to subtractive methods.

3D printing is a great option if you have rough, complex features such as undercuts and complex surfaces, and don't necessarily need surface accuracy better than ±0.125mm (standard machining). Tolerances beyond standard machining must be achieved using subtractive methods, either through manual or machine processing, for both 3D printed and CNC models.

SLA has the highest tolerance compared to other commercial 3D printing technologies. The tolerances for stereolithographic 3D printing are somewhere between standard and precision machining.

In general, more malleable stereolithography materials will have a wider tolerance zone than more rigid materials. Designing subassembly parts for tolerance and fit reduces post-processing time and simplifies assembly, as well as reduces material costs per iteration.

There are many other factors to consider when evaluating 3D printers. Should your models be isotropic? What mechanical properties should your models (and, accordingly, the materials from which they are made) have? The best place to start is to get familiar with the physical models printed on a 3D printer. Order a free material sample from Formlabs of your choice and see for yourself the quality of your stereolithography print.

Top 12 3D Printers - Ranking 2021 (Top 12)

The formation of any new industry generates a lot of concepts and their practical implementations. Three-dimensional printing has become widespread only in recent years, and it is still quite difficult to predict the prospects of a particular technology. We tried to present the ranking of the best 3D printers as of the beginning of 2021.

To date, the most numerous representation in the "home" segment of this market have Fused Deposition 3D Printers (FDM) , and complex geometries with increased precision can be realized with Stereolithography (SLA) . At the same time, already within the framework of these technologies, there is also a competitive struggle for a place under the sun. More precisely, a kind of differentiation according to "niches".

How to choose a good 3D printer?

Types of 3D printers

3D printers with layer-by-layer fusing are usually classified according to the types of implemented kinematic scheme.

• With table movable in a horizontal plane (design by Josef Prusha). The most simple and affordable. Due to objective reasons, they have low accuracy and limitations on the types of plastic used due to the difficulty of ensuring the desired temperature regime.
• With table that moves vertically only (H-bot, CoreXY, Ultimaker and variations). Each subspecies has its advantages and disadvantages, but in general, 3D printers of this class print better than the first ones, have good potential for improvement and support all the existing variety of modern plastic (theoretically).
• Delta printers and robots . The fastest of the FDM models, but with very high requirements for frame rigidity, manufacturing accuracy of supports and guides, the weight of the moving part, the power of the "brains", etc.

The first stereolithographic printers were based on the polymerization of a special resin under the influence of laser radiation of a certain wavelength and cost a lot of money. In principle, over the past couple of years, the situation has changed only in relation to the price of photopolymers. The indisputable advantage of this category of devices is the high printing accuracy, sufficient for master modeling, jewelry business and elite dentistry.

The use of powerful LEDs instead of lasers has dramatically reduced the cost of stereolithographic 3D printers. Naturally, due to a partial loss of accuracy, insofar as laser printing technology operates with a wavelength, and LED technology operates with the pixel size of the projecting LCD screen (currently it is approximately 50 microns). The situation is exacerbated by various concomitant parasitic effects. In particular, the scattering of an unfocused beam of light.

When choosing, keep in mind that, ideally, photopolymer printing needs additional devices for removing resin residues (washing) and additional illumination of finished models for their complete curing (dryer).

Materials

The second, no less important aspect of the quality of 3D printing is the materials used. For printers with layer-by-layer deposition, their diversity is an order of magnitude higher. What is worth only a large group of engineering plastics: glass- and carbon-filled, refractory, conductive, flexible, etc. Naturally, all this wealth works correctly only if the necessary temperature conditions are observed during the printing process, which is achieved mainly in closed cube-type structures.

In the camp of photopolymers, things are even sadder, since their assortment is much more modest. In addition, the print time depends on the color of the material (wavelength), and the difference is really impressive. Well, the price tags are relatively humane here can only be called "consumer goods". At the same time, the pace of development of this category of consumables is higher, as is the dynamics of their cost reduction.

Construction area size

Another defining criterion when choosing a 3D printer is how large are you planning to print? Most low-cost fusion printers have a cubic or cylindrical working area with a side (base diameter) of 200-250 mm. At the same time, delta-shaped structures make it possible to obtain higher one-piece models. Too small size? Focus on 3D printers with an increased workspace, but the variety of those is not very large.

Other functionality

Wi-Fi interface allows you to do without an additional cable on the table. Please note that experienced printers advise you to connect to the router using a static IP address. With the help of the second extruder it is very convenient to print water-soluble supports. The ability of the printer to remember where it stopped to resume printing in case of failures or the end of the filament can also be useful.

In our review, we tried to cover all popular areas of conditionally home 3D printing in the spring of 2021.

So far, only wealthy people or great enthusiasts can afford to choose 3D printing as a hobby. At the same time, the latter are likely to pay attention to the simpler devices of the RepRap category, which allow endlessly improving the design.

Representatives of small businesses are another matter. They need the result "here and now", if possible with minimal additional time losses to refine this tool of production. In any case, a good 3D printer should be chosen for a specific task. There are no universal solutions here, although there are some general signs of a professional level. In particular, this is a closed case, which significantly expands the versatility of the 3D printer and allows the use of special types of plastic on it. Another example is models with two extruders, without which it is impossible to implement really complex tasks.

Good luck!
