So you’ve decided to get into the world of 3D printing. Where do you begin? There are printers for every possible requirement, and there’s a lot of jargon floating around that makes it hard to accurately compare different models. Relax – we’re here to help.

XYZPrinting is known for creating some of the best entry-level 3D printers around. Today, we’ll be looking for any strengths or weaknesses that the Da Vinci Mini might have– it’s a small printer, but it’s certainly capable. However, is it right for you and your needs? You’ll have to read on to find out.

    Design

    The XYZPrinting Mini comes pre-assembled, so there’s no need to factor in build time. It’s a small-sized unit, perfect for sitting on your desktop, but this does mean that the build area is similarly restricted. Don’t get us wrong – you’ll be able to print decent-sized models, but nothing too huge.

    Notice how there’s no enclosure? This means that it’ll be a little louder when you print, but all things considered, it’s still fairly quiet since the mechanical parts are mostly covered by the plastic frame. There are also implications for heat retention, but that’s not an issue, as we’ll explain later.

    You get exactly what you’d expect from a low-end printer: there’s a single extruder and a maximum speed of 100mm/s. This is fairly standard and just means that you’ll take slightly longer to print. However, as the build area is only around 6” in each direction, you won’t be waiting hours unless you’re trying to print a large, solid cube.

    Printing

    There are three different speeds to choose from. As expected, the faster you print, the rougher the final quality. We found that the fastest setting resulting in significant stepping on curved surfaces, while if you allow it to take its time, your models look far better, but still not professional-level.

    In an attempt to keep things as simple as possible for new users, XYZPrinting has limited the Mini to using PLA filaments. This removes the need for an enclosure but does restrict you somewhat in terms of the things you can build. Still, for beginners, PLA is more than enough to get you started.

    The overall quality of the prints is too low for manufacturing, and the build volume too small for mass-production. However, it’s perfect for people looking to print things for their home or office. Better still, it takes any 1.75mm PLA filament – not just those made by XYZPrinting.

    Features

    So what other features does the Mini have to make things easier for beginners? Well, instead of adding things, XYZPrinting has removed components. There’s no heated bed, for instance, and no built-in screen. You do have a USB connection, though, and WiFi functionality, which is almost unheard of in low-budget printers.

    We were pleased to see that drivers are available for both Windows and Mac computers. On the other hand, there’s no Linux support. It supports four different file types, though, so you’re not really limited to using a particular modeling program, which is great.

    Even the interface is simplistic. There’s a single button for starting a print and a status LED that lets you know how your print is going. All in all, it’s easy to use even if you’re not particularly tech literate. Let’s be honest – that’s never a bad thing.

    Cost

    Here’s the thing: the Da Vinci Mini isn’t available in the United States. You can buy it from several European locations, though. It costs around $700, which makes it among the cheapest, most robust 3D printers we’ve covered. Of course, you’ll have to find a company to ship it over if you’re in the US.

    Running costs are minimal. PLA is among the least expensive materials you can use, and since while third-party filaments aren’t supported, you can easily mod it to accept them. Large spools of PLA often cost less than $20 so really, your monthly material costs will depend on how often you print.

    We think that this 3D printer is appropriately priced. It’s clearly intended for novice users, and the price point helps it stay affordable, unlike more advanced printers that offer user-friendly features. You’ll likely outgrow it in a year or two, but until then, it’ll serve you well.

    Support

    XYZPrinting’s support section provides customer help telephone numbers for 11 different countries. Best of all, each of these can talk to you in the native language or English. This is almost unheard of, and we’re genuinely delighted to see this level of help being offered for free.

    The limited warranty period is similarly outstanding. You’re covered from factory defects for up to two years at no extra cost, presuming you bought the printer from one of XYZPrinting’s recommended sellers. There’s no option to extend this warranty, though, which is a bit of a shame.

    Customers can consult model-specific FAQs and tutorials in case they need any technical help. There are also different versions of the software, as well as documentation for each printer model here. All in all, it’s one of the most comprehensive support packages offered by any major 3D printing manufacturer.

    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 brag about. But this is nothing new. Resolution wars have been fought since digital became popular and the printing industry became one of the first battlegrounds. 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 detail.

    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 SLA 3D printers using 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. Although stereolithography printers typically produce significantly thinner layers, 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 based on numbers alone. nine0003

    3D printers based on DLP technology have a matrix of pixels that is fixed 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 with SLA and LFS 3D printers (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).

    Learn more about the differences between SLA and DLP technologies in terms of resolution, accuracy, clarity, print volume, surface quality, speed, and how they work. nine0106

    In the world of 3D printing, no other factor affects the quality of models more than XY resolution. She is often mentioned, but rarely understood. The definition of XY resolution (or horizontal resolution) differs depending on the 3D printing technology:

    • stereolithographic 3D printers - a combination of laser spot size and the size of the steps with which the beam can be controlled;
    • DLP printers - pixel size, the smallest detail that a projector can reproduce in a single layer; nine0040
    • FDM printers - the smallest distance that the extruder can move within one layer.

    Generally, the lower this value, the finer the detail. But this number is not always indicated in the technical specifications, and even if indicated, it is not always correct. To get an idea of ​​true XY resolution, it is important to understand how a printer works.

    How does XY resolution affect the quality of your models? To find out, we decided to test a Form 2 stereolithographic 3D printer. The size of the laser spot in the Form 2 printer is 140 µm (FWHM), which should allow it to reproduce fine details on the XY plane. We decided to check if this ideal resolution corresponds to the truth. nine0003

    To check the minimum feature size on the XY plane for the Form 2 printer, we designed a model (left) with lines ranging from 10 to 200 µm thick and printed it using Clear Resin (right).

    We first designed and printed the model to check the minimum element size on the XY plane. The model is a rectangular block with lines of various widths in the horizontal, vertical and diagonal directions, which are applied to prevent displacement. The line thickness is from 10 to 200 µm, the lines are drawn at 10 µm intervals and have a height of 200 µm, which corresponds to two layers when printed at a resolution of 100 µm for the Z axis. Made from Clear Resin, the model was washed twice in isopropyl alcohol and subjected to a within 30 minutes. nine0003

    The model was photographed and painted green for better visibility. The vertical yellow line with black dots on the right side of the window is for measuring the width of the photographed line.

    After the final polymerization, we placed the model under the microscope and took a high resolution photograph for further analysis. Using ImageJ, a free image analysis program from the National Institutes of Health (NIH), we scaled the image pixels and measured the actual width of the printed lines. We collected over 50 data points per line width to eliminate measurement errors and variability. We analyzed three models made on two printers. nine0003

    The results show that the Form 2 has the same ideal and actual XY resolution for model elements as small as 150 µm.

    As the line width decreases from 200 to 150 µm, the ideal values ​​are within the 95% confidence interval of the measured value. As the expected linewidth becomes less than 150 µm, the measured interval starts to deviate significantly from the ideal. This means that the printer can reliably reproduce elements up to 150 microns in size, as thick as a human hair, on the XY plane. nine0003

    The Form 2 printer has a minimum XY feature size of about 150 µm, only 10 µm larger than the spot size of the 140 µm laser installed in it. The minimum element size cannot be less than the laser spot size. There are many factors that affect this value: laser refraction, microscopic contaminants, polymer chemistry, etc. Considering the entire printer ecosystem, a difference of 10 µm is nominal. Not all 3D printers have the reported resolution as the actual resolution, so it's a good idea to do a lot of research before choosing the right resolution for your project. nine0003

    If you want models with fine detail, look for a printer whose XY resolution isn't just listed as a number, but backed up with measured data.

    When looking at the specifications of 3D printers, you will find that one parameter appears more often than any other. This is the Z-axis resolution. Also known as layer thickness or layer height, vertical resolution was the first major numerical parameter by which early 3D printers were distinguished. The first such devices struggled to overcome the barrier of 1 mm, but now the layer thickness in FDM-based 3D printers can be less than 0. 1 mm, and even less in LFS and SLA printers. nine0003

    Formlabs 3D printers support layer thicknesses from 25 to 300 µm, depending on the material. This range of values ​​allows you to find the perfect balance between speed and print quality. But the main question is what layer thickness will be ideal for your model.

    The high resolution of 3D printing affects other parameters. The thinner the layer, the more layers need to be printed, resulting in increased model production time: typically, printing at a resolution of 25 µm takes four times longer than printing at a resolution of 100 µm. In addition, the more layers, the higher the probability of errors. For example, even with a layer success rate of 9A 9.99% fourfold increase in resolution reduces the chances of a successful print of the model from 90% to 67%, provided that the layer with the error leads to rejects.

    The thinner the layer, the longer it takes to print and the more likely it is to cause errors and distortion.

    Is it true that the higher the resolution (the thinner the layers), the higher the quality of the finished models? Not always. It depends on the model and resolution of the XY 3D printer. As a general rule, the thinner the layer, the longer it takes to print and the greater the chance of distortion and errors. In some cases, printing models at a lower resolution (i.e., with thicker layers) may even result in better quality. nine0003

    Thinner layers are usually associated with smoother diagonal transitions, causing many users to push Z resolution to the limit. But what if the model consists mostly of vertical and horizontal faces, with right angles and a small amount of diagonal surfaces? In such cases, increasing the number of layers will not improve print quality.

    The problem is exacerbated if the printer's XY resolution is not ideal and it "goes out of bounds" when forming the outer edges. The more layers, the more mismatched protrusions will be on the surface. In this case, the finished model will look much worse, even if the Z resolution is higher. nine0003

    There are times when you need to increase the resolution. If you have a printer with good XY resolution and a model with complex features and many diagonal edges, reducing the thickness of the layers will allow you to get a much better quality physical model. Also, if this model is small (no more than 200 layers), then increasing the resolution of the Z axis will lead to a real improvement in quality.

    Some design features benefit from higher Z resolution: organic shapes, rounded arches, fine embossing and intricate engraving. nine0186

    A tiny model with lots of detail and arches needs a higher Z resolution. This cathedral was printed on a Form 2 printer at 25µm resolution.

    Try to stick to this general rule: print thicker layers and increase the Z resolution only when it is really necessary. With the right combination of printer and model type, the higher Z resolution will capture the intricate details of your design. nine0003

    Gray Resin allows printing at a resolution of 160 microns. Check out the difference in speed for yourself.

    Formlabs PreForm software allows you to select the layer thickness. Starting with version PreForm 3.0.3 , Gray Resin can be printed with 160, 100, 50 and 25 µm layer heights. Printing at a resolution of 160 microns will speed up the iteration process and allow engineers to move from design to finished model even faster. And dentists can make more aligners per day without sacrificing quality. nine0003

    We hope that once you are familiar with the concept of resolution and understand the differences in 3D printing technologies and results, it will be much easier for you to choose a 3D printer that best suits your needs and workflow.
