High res 3d printer

What is Resolution in 3D Printing? X, Y, and Z Resolution

The technical definition of resolution in 3D Printing is the shortest distance a 3D printer nozzle travels when depositing filament.  

If you’ve ever purchased a phone or television (or maybe you made your girlfriend/boyfriend get them for you), you’d have come across the term resolution frequently. You’ll know that a 1080p screen has better picture quality than that of a 720p screen. 

Likewise, in 3D printing, a high resolution 3D printer is by far the most important factor to consider when buying a printer if you want high-quality prints.

You’ll often hear terms like Z layer resolution and XY resolution in 3D printer reviews. The Z layer resolution is the height of a single layer in a 3D print. The X and Y resolution, on the other hand, is the shortest distance the nozzle travels in the horizontal direction.

Other Factors That Affect Print Quality

Material

Not all materials print with the same quality: some materials produce higher quality prints than others. 

Printer Stability

Vibrations during printing can hamper 3D printing accuracy. That’s why a sturdy, stable printer is important. All metal printers are sturdier than plastic printers.

Type of Printing

Resin printing produces a higher resolution of prints than FDM printing. 

Temperature

Different plastics print better at different temperatures. For ABS, extrusion temperatures of up to 240-250°C are ideal for accurate prints. PLA on the other hand benefits from temperatures of 200-220°C.

Slicer settings

Slicer settings play a big role in print quality, so make sure you play with these settings to get the perfect print. The layer height will have a big effect on print quality and print speed.

Nozzle size

The smaller the nozzle size, the more accurate and high resolution the print.

When Do High-Quality 3D Printers Make the Most Difference?

High-quality 3D printers don’t make much of a difference on basic flat surfaces like a cube. A cheaper less accurate printer can even produce the same cube in a shorter period of time (because the nozzle diameter size is larger which means it deposits more filament in less layers).  

But if you love printing intricate miniatures, prints with curved or diagonal surfaces, or embossings and engravings, then the difference between a high resolution 3D printer vs a low-resolution printer is blatantly obvious.

Advantages and Disadvantages for High Resolution 3D Printers

High-quality 3D printers don’t make much of a difference on basic flat surfaces like a cube. A cheaper less accurate printer can even produce the same cube in a shorter period of time (because the nozzle diameter size is larger which means it deposits more filament in less layers). 

But if you love printing intricate miniatures, or prints with curved or diagonal surfaces, or embossings and engravings, then the difference between a high resolution 3D printer vs a low-resolution printer is blatantly obvious.

Advantages

Print Quality 

Higher resolution printing naturally leads to smoother surfaces, finer details, and more accurate printing.

Efficient Workflows

High-res printing also leads to efficient workflows while being uncompromising on speed and quality.

More Variability in Creating Objects

These 3D printers can create the most intricate and complex of designs while maintaining quality. 

Picture a model or a sculpture in your head. You can make a real-life version of that with the help of a high res 3D printer.

Disadvantages

Slow Speed

It’s not all sunshine, rainbows, and popcorn with high resolution 3D printers. A piece that may take an hour with a lower res 3D printer will take four hours to print on a high-res one. 

More error-prone

The more layers in a print, the more time it takes to print, and the greater the chances of a printing error.

Requires Precise Calibration

Your printer setting game needs to be tight to get the highest resolution prints possible. The extrusion and bed temperatures must be just right, and the right nozzle must also be selected.

SLA VS FDM

Like we briefly touched on before, SLA (aka resin) 3D printers produce far more accurate prints than FDM printers. 

SLA printers use UV or laser to cure the resin. These two light sources have different spot sizes. Anycubic Photon Mono X, a popular resin printer, has an XY resolution of 0.05mm and a Z layer resolution of 0.01mm. The resolution of most high-end consumer printers falls in this range.

On the other hand, FDM 3D printers don’t compare to resin printers. For example, one of the best FDM printers, the Prusa i3 MK3S+, has a Z layer resolution of only 0.05mm.

Which is Stronger: FDM or SLA?

SLA might trounce FDM in detail quality, but when you start looking at part durability, the tables suddenly turn. FDM prints are much stronger and more durable than SLA prints.

Although SLA can produce extreme details, the prints are often brittle. They don’t withstand impacts and snap or break easily. You shouldn’t use SLA for parts that require any mechanical strength — its value is in the looks.

FDM thermoplastics, on the other hand, are generally used even in heavy industries for functional parts. That should tell you all you need to know about their strength.

The ultimate durability of FDM parts depends on the material, how you printed it, and which printer you used. But in general, FDM is much stronger than SLA.

What is the Effect of 3D Print Resolution on Speed?

Speed is one of the main considerations in 3D printing, whether high or low resolution. When it comes to high-res 3D printing, you unfortunately have to sacrifice speed.

The general rule of thumb is that the higher the resolution, the lower the print speed.

That might be disappointing to hear, but it only makes sense. Just like it takes you longer to draw a more detailed picture than a stick figure, 3D printers take longer to cram in all the detail to high-resolution prints.  

That said, printer manufacturers are locked in a constant battle of finding the optimal ratio of resolution vs. speed. Many of the printers on this list will produce great results in a relatively short time.

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.

Extremely High Resolution 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.

Accurate 3D printers we recommend

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. Source: Shapeways.

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.

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: Check latest price at Anycubic 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: Check latest price at Elegoo here / 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.

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.

We also have an article about how to maximize dimensional accuracy and precision in 3D printing.

Best High-Resolution 3D Printers of 2022: A Complete Buying Guide

Resolution is a little-understood aspect of precision 3D printing, and there are many important factors that affect print quality beyond layer height. This article recommends the best high resolution 3D printers, explains the factors that make up a high resolution 3D printer, and the advantages and disadvantages.

Usually, when choosing a resolution for 3D printing, the Z-axis resolution, or Z-resolution, is the most discussed. This is the vertical resolution, which refers to the minimum height or layer thickness possible for a 3D printer. nine0003

Smaller layers mean better resolution and better surface finish on parts with smoother surfaces and sharper edges.

So having a high quality 3D printer that can print at low layer heights can be a big advantage. However, this is not the only factor that affects print quality, there are many others that affect whether a high resolution 3D printer actually prints accurate and smooth details.

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

The Z resolution corresponds to the layer height of the 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 print details: the ones that are inside each 2D layer. Then the Z-axis adds several layers, representing the height - the third dimension. Although these are all axes, the XY and Z axes are controlled by two different systems, with some FDM printers having a much finer resolution in Z than in XY. nine0003

low and high resolution in 3d printing layers

X and Y resolution is the smallest movement of the printer's print head (projector, extruder or laser, depending on the technology) within the layer - horizontally.

Various 3D printing technologies are able to provide better resolution than others. For example, SLA 3D printers are more accurate than FDM 3D printers, although their Z-resolutions may look the same on paper. This is mainly due to the better XY resolution resin 3D printers can print at, resulting in smoother surfaces, and better resin printers are able to print parts with barely visible layer lines. nine0003

However, other factors can significantly affect print quality.

Other factors affecting print quality

• Nozzle size: Smaller nozzles on FDM 3D printer extruders allow more complex and precise parts to be printed. Standard nozzles are typically 0.4mm, although much smaller 0.1mm or 0.2mm nozzles are available for printing small and precise parts. They are also better suited for printing supports and ledges.
• Frame and Vibration Stability: The strong, heavy metal frame that secures the printer and print bed to the ground is less susceptible to vibrations and other external 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 accuracy in 3D printing. nine0014
• Slicer and Printer Settings: Your 3D slicer settings will be critical to print quality, and even the highest resolution 3D printers will print poor quality models if not optimized.

When do high quality 3D printers matter the most?

If you are planning to 3D print a very simple structure, like a cube, then using a high quality 3D printer, using large or small layers will make no difference. In fact, using low layer heights will cause the exact same print to take much longer. nine0003

For these very simple models with few complex parts, a regular cheap 3D printer will work almost as well as a high resolution industrial 3D printer that costs 20 times more.

However, high-quality precision 3D printers greatly improve the quality of more complex parts that have diagonal or arcuate lines or sides, as well as embossing and engraving.

Particularly for curved or diagonal parts, the lower the layer height and the more precise the printer, the less stepped these elements will look and the smoother they will look even up close. nine0003

Very high resolution 3D printers such as resin printers are commonly used to 3D print jewelry molds such as this 3D printed ring.

What's more, if you're printing a small part, such as 3D printing a miniature or desktop model, using an accurate printer with a very low layer height can be worth it, because even if it takes several times longer, it still won't take over an hour. nine0003

Belt tensioners, a 4.2.2 32-bit motherboard, and silent stepper drivers do a lot to present a printer that feels much more modern than the Ender 3. 3 V2 is not amazing: the layer resolution is only 100 microns. But don't be fooled: high resolution printing is only defined by high resolution.

In action, the Ender 3 V2 is built to a level of precision that seems unusually high for an inexpensive FDM printer. With few visible, warping or layering issues, with excellent overall quality for large parts and decent results for small, detailed parts. Added to this is a fairly large build volume - 220 x 220 x 250 mm to be precise - for large projects and even for small-scale printing. nine0003

For the price, you also get to work with a decent range of materials - PLA, ABS, PETG, TPU. The only caveat is that you'll have to stick with simpler prints that are relatively free of complex embossing, small details, narrow arches, and the like.

In our experience, the Ender 3 V2 works best when creating household items such as plant pots or, say, vases, figurines, toys, accessories, and the like. We are sure that his printing abilities will be enough for a modest business selling non-geometrically complex products. nine0003

Keep in mind that the Ender 3 V2 is largely a hobby printer that needs a fair amount of tweaking to get the best results. Curious beginners and seasoned makers should find this an enjoyable part of the printing process, but "green" beginners may prefer an option with fewer "practical" aspects.

Benefits of High Resolution 3D Printer

Best Quality: High resolution results in a smoother surface, with excellent detail and detail aesthetics.

The only way to get fine details: models that have arches and sharp diagonal details can look very jagged at high layer heights, and low resolution 3D printers can't adequately print those details.

Ideal settings required: improved accuracy requires perfect calibration, perfect temperature settings to avoid filament or resin defects, and proper bed temperature and adhesion on the platen. Any errors here may result in defects in the print.

Significantly slower: prints with a 25 micron layer height four times longer than with a 100 micron layer because four 25 micron layers equals one 100 micron layer height. Large and complex models may take several days to print. nine0003

Higher chance of print failure: The more layers a model has, the more chances for errors to occur that can render a part useless.

High-Resolution 3D Printing Technologies

High-Resolution 3D Printing Technologies include:

FDM - Fused Deposition Modeling

Resin (SLA, DLP, LCD)

Photopolymerization, commonly known as resin 3D printing, involves projecting a laser or light source to cure a liquid photosensitive resin into layers. Specific technologies include stereolithography (SLA), low power stereolithography (LFS), masked stereolithography (MSLA), and digital light processing (DLP). Resin printers typically achieve a layer resolution of 25-35 microns.

MJF - multi-jet simulation

Multi-jet modeling, or material inkjet, uses inkjet printheads to layer-by-layer melted materials to create a 3D part or model. Expensive and high-precision MJF printers are a reserve of large companies with a large treasury.

PolyJet - Resin Inkjet

PolyJet, or photopolymer inkjet, printers use layers of photosensitive liquid photopolymer resin to create prints, which is fed through the printheads and cured by exposure to ultraviolet light. Like the MJF, the PolyJet is expensive, although the printers are usually smaller. nine0003

High Definition 3D Printer FAQ

Are high definition 3D prints more durable?

No, on the contrary. Generally, thicker layers (or lower resolution) produce harsher results. This is because they minimize the number of contact points between layers. Fewer layers in contact with each other means less chance of bond strength problems.
However, print strength depends on many factors, including adhesion and layer height, extruder and bed temperatures, media quality and type, and the printing technology used. The definitive answer depends more on the specific printer than the resolution. A capable device, such as any of the best high resolution 3D printers, produces reliable parts at higher resolution. nine0163

What is high resolution 3D printing?

The answer to this question varies greatly depending on who you ask. To keep things simple, high-resolution 3D printing is best described as the process of printing parts with a higher overall quality—whether it be smoothness, quality of finish, detail, or model fidelity—than is typically found in the realm of 3D printing.

What can be done with a high resolution 3D printer?

High resolution 3D printing suitable for a wide range of applications. In the commercial realm, companies prefer high-resolution printing in areas such as dentistry, jewelry, biomedicine, and all kinds of functional prototyping where accuracy is critical. In the hobby realm, creators are turning to high-resolution printing for projects that require fine detail, such as figurines, modeling, and other decorative items. nine0003

How does 3D printing resolution affect speed?

Higher resolution reduces speed.
Print speed refers to how quickly the printer applies each layer. Because high resolution printing is synonymous with thinner layers, print speeds are typically slower than low resolution printing. With high-resolution 3D printing, printing speed is sacrificed in favor of accuracy. The exact time depends on the desired resolution, the underlying technologies of the printer being used such as resin or MJF, and the complexity of the model. nine0163

What Does Resolution Mean in 3D Printing?

Looking for a high resolution 3D printer? “Resolution” is a term from the field of 3D printing and additive manufacturing that is often talked about, while rarely understanding its meaning. How does XY and Z resolution affect the quality of 3D printed models? What is the minimum element size and what layer thickness should I choose?

This detailed guide explains how 3D printer resolution affects model printing and how it differs between SLA, FDM and DLP printers. nine0003

For decades, technology manufacturers have been striving for higher resolution than their competitors. TVs have recently quadrupled their pixel count from HD to 4K, but manufacturers are already thinking about pushing the resolution to 8K. Mobile phones, tablets and other devices with screens show resolution as one of the main characteristics, if, of course, they have something to boast about. But this is nothing new. Resolution wars have been fought since the days when digital became popular and the printing industry became one of the first battlefields. nine0003

If you lived in the 80s and 90s, you'll remember how Canon, Brother, HP, Epson, and Lexmark (among others) sought to improve print speed and resolution. 100 x 100 dpi quickly grew to 300 x 300, then to 600 x 600. Finally, now the standard resolution is 1200 x 1200 dpi. Then these values ​​were extremely clear, and the use of units of measurement was quite logical. Unfortunately, things get much more complicated when you add another dimension to print. nine0003

The level of detail of the model depends on the resolution of the 3D printer in all three dimensions.

In 3D printing and additive manufacturing, there are three dimensions to consider: two planar 2D dimensions (X and Y) and a third dimension, Z, which is used for 3D printing. Since planar measurements and Z measurements are usually controlled by completely different mechanisms, their resolutions will differ. Therefore, they must be considered separately. As a result, there is a lot of confusion about the interpretation of the term "3D printing resolution" and false expectations for print quality. nine0003

Formlabs high-resolution stereolithographic 3D printers feature high Z-axis resolution and a low minimum element size on the XY plane, allowing them to capture fine details.

What affects the high resolution of a 3D printer? It is impossible to name any one isolated factor. Since 3D printers produce models in 3 dimensions, there are at least two factors to consider: the minimum size of the XY plane elements and the resolution of the Z axis (thickness or height of the layer). Z-axis resolution is easy to determine and is therefore more commonly reported, although it is less related to print and surface quality. The more important XY resolution (minimum element size) is measured with a microscope and is therefore not always found in specifications. nine0003

In practice, this means that the 3D printer must perform well in both categories (in all 3 dimensions).

A lot has changed since the first desktop 3D printers hit the market. Now stereolithographic (SLA) 3D printers such as the Form 3 directly compete for desktop space with Fused Deposition Modeling (FDM) 3D printers. One of the main advantages of 3D printers that use polymers as consumables over their plastic-melting counterparts is print quality: SLA printers produce models with a smoother surface and a higher degree of detail. While stereolithography printers typically achieve significantly thinner layer thicknesses, the reason for the improved print quality is the much higher XY resolution. nine0003

SLA printers (right) have higher resolution and produce models with smoother surfaces and more detail than FDM printers (left).

Unlike 3D printers based on FDM technology, the minimum size of elements in the XY plane in stereolithographic 3D printers is not limited by the dynamics of the flow of molten plastic, but is more determined by the optics and kinetics of radical polymerization. Although the calculations are complex (and beyond the scope of this article), it can be said that the details on models produced by stereolithography printers are about the same size as the diameter of the corresponding laser spots. And laser spots can be very small, especially when compared to nozzles on FDM printers. nine0003

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.

Technologies Resin-based 3D printing such as SLA, LFS and DLP provide the highest resolution of all 3D printing processes available for desktop printers. The primary units of measure for SLA and DLP processes are different forms, making it difficult to compare printers on a purely numerical basis. nine0003

DLP-based 3D printers have a fixed pixel matrix relative to the work area, while SLA- and LFS-printers that use a laser can focus the laser beam on any coordinate of the XY plane. This means that laser 3D printers with high optical quality can accurately reproduce the surface of the model, even if the laser spot size is larger than the pixel size in the DLP printer.

Whichever resin 3D printing technology you choose, professional 3D printers should capture the finest details of your creations, from photorealistic models to fine jewelry. nine0003

When printing on 3D printers based on SLA and LFS technologies (left), layer lines are almost invisible. As a result, surface roughness is reduced, resulting in a smooth surface, and when using transparent materials, models with greater transparency. DLP printers use rectangular voxels to render images, which can result in vertical lines (right).
