- Machinery Critic
Produces quality prints and it's easy to use. Has a clean, smart design that shares the silver-and-blue color scheme of Dremel tools. It's an enclosed printer, so the large print area is surrounded by plastic panels that keep fingers away from the moving and hot parts.
- Tom's Guide
The touch screen is among the noteworthy features that will grab your attention when you first see the printer. It is colored and helps you to configure your printing needs with relative ease and excitement. If you are looking for a printer that offers consistent quality and ease of use, try the 3D20 and experience the simplified process.
- Pen and Plastic
Dremel really pushes ease of use. Everything from the interface to actual creation process is as simple as possible. You can even download “pre-modeled” models from their website to get started. There are also constantly adding to these models (for example: chess pieces, Christmas tree ornaments, etc…).
- Total 3D Printing
The customer service is definitely up there with the best, as well as giving an industry’s best 1-year warranty, so you can have peace of mind after adding this 3D printer to your arsenal.

What experts didn't like

The 3D20 is strictly a desktop 3D printer for starters and should look like it. Therefore, its limited building capacity, non-layered print-beds, and filament removal issues are things you should deal with.
- Machinery Critic
Officially supports only expensive Dremel filament. Cloud printing service can't edit models.
- Tom's Guide
You’ll have to use Dremel’s software to print your models. It works most of the time but can run into some problematic network errors that require you to continually restart the printer. They’ve released updates since I’ve owned it, which is good, but I think more work needs to be done here. This is another drawback of using a “closed” system that can’t leverage the value of open source software out of the box.
- Total 3D Printing
The build volume isn’t the largest and there are definitely 3D printers with larger bed surfaces. If you know in the future you are looking to print large projects, you might want to opt-in for a larger machine.
- 3D Printerly
It’s not connectable by WiFi or ethernet, so you’ll have to make do with an SD card or resort to its 4GB internal memory.
- 3D Sourced
Runs only with Dremel PLA filament. Do not provide WIFI connectivity.

An Overview On 3D Printers

A 3D printer is a marvelous piece of technology that is taking businesses and home offices by storm. In a short amount of time and with the right designs, you have the ability to print almost anything. For example, you can print useful household items like bowls and plates if you accidentally break a piece of your dinnerware. You can print a planter for your new herb garden, or even a simple stationary holder for your desk. If you want to print a small set of cutlery for taking to work or school, you can print out a unique fork, knife and spoon from your 3D printer as well.

In addition to household items, a 3D printer can also print out toys for your kids. Whether they are into dinosaurs or blocks, you can find patterns to print for numerous playthings. From whistles to fidget spinners to toy cars, almost any toy can be created using a 3D printer at home. Plus, you can also print accessories for yourself, like a wallet or orthotics for your shoes. There are endless possibilities to take advantage of when you have a 3D printer.

There are several different types of 3D printers on the market, each with their own advantages. A fused deposition modeling (FDM) printer is a basic one that is loved by beginners to 3D printing. It works by heating a filament and shaping it along X, Y and Z axes. Within this category, there are two different types of FDM printers: cartesian and delta. A Cartesian FDM printer moves the printing bed on the Y axis, while the other two axes move with their own motors. Most FDM printers work this way as it is highly precise. A delta FDM printer has three motors on individual rods, which is not a common model.

Stereolithography (SLA) printers use a process that involves a chemical reaction to form layers of print. It is a highly precise result with smooth prints. This kind of model is perfect for printing items that require extremely fine printed details. A similar model is the digital light processing (DLP) printer. It works by using light, which targets a specific area of the resin and hardening it into a sculpture.

Both SLA and DLP models produce exceptionally smooth prints as compared to an FDM model, which can have rougher results. If you want to print industrial parts, then a selective laser sintering printer is a good choice. The process it uses involves laser precision, and is good for highly complex designs and detailed items.

In addition to the type of 3D printer you need, you’ll also have to consider what kind of printing materials are best for the objects you want to create. If you’re going with a printer that uses filament, you have a couple of options. Polylactic acid (PLA) is a kind of plastic made from plants. It can be useful for creating items for indoor use. However, it does deteriorate after a lot of sun exposure, so you shouldn’t use it for any items that are kept outdoors. Polyethylene terephthalate glycol (PETG) is a food-safe plastic. If you want to use it to create items like plates or cutlery, you will still need to finish it with a food-grade epoxy. Acrylonitrile butadiene styrene (ABS) is a a highly sturdy plastic that is perfect for items that will be used outdoors.

If your are going with a SLA or DLP printer that uses resin, then you can choose the quality of liquid resin you need based on what you’re making. Standard resin is a good option for small gadgets like pencil holders. Professional resin is best for engineering applications that will see high impact and high usage. Medical-grade resin is often used for making custom dental work or hearing aids.

The 3D Printer Buying Guide

  • The type of 3D printer you need will really depend on the kinds of objects you want to print. That’s why it’s best to consider the range of needs you have before purchasing a printer. For example, if you primarily want to print household objects for indoor use, then you can use an FDM printer. For objects that you will be using outdoors, the type of filament is what will make a difference. You have to use an ABS filament that can withstand the sun. If your goal is to print artwork with your 3D printer, then it’s best to use a resin printer, which will be able to handle the delicacy of your designs, unlike an FDM printer. For tools, opt for an FDM for home use. For professional-grade tools, then you will need to use a resin-based 3D printer.
  • An important factor to note for 3D printers is resolution. The resolution for 3D printers is measured in a unit called microns. For example, an FDM printer, which is most common for individual use, has a resolution of 25 microns. Resin-based 3D printers, which are common for professional applications, have a resolution of 100 microns. This means that you will get much finer details on a resin printer. Consider the kind of details you need printed and how smooth the object needs to be. The higher the microns, the higher the precision of the printer.
  • In addition to the hardware of the actual 3D printer, you’ll also need software to create the printer files. The software program for your computer, on which you create the 3D printing files, is referred to as a slicer. Popular slicing software includes Cura and Slic3r. There are other slicer software options available as well. Be sure to read reviews online before landing on a 3D printing software for your computer.
  • Making a 3D printed object can take time. During the printing process, your printer may be interrupted by a number of issues. As a result, the object that you’re printing can be ruined in progress, wasting resources and time. In order to reduce the amount of unexpected interruptions during the 3D printing process, look for a printer that has a print resume feature. This will ensure that your print isn’t ruined partway through as a result of an issue. If the printer does have to pause, it can easily pick up where it left off with your object.
  • The first layers of your printed object are like the foundation of a house. Everything else rests on those layers, and it’s is critical that they are well-formed, stable and staying in place. In order to ensure that the bottom layers of your print are solid, you will need a heated bed. Different types of filament have specific temperatures they require in terms of heat, so you may need to experiment to find what is right for you.
  • An intuitive user interface will make all the difference on your 3D printer. If you have one that is manual, such as one with a rotary knob, it can be difficult to navigate. Even a touchscreen that is confusing can cause unnecessary problems with your printing process. Look for a streamlined touchscreen user interface that is easy to understand and doesn’t require complex instructions.
  • When you first start using your 3D printer, you may have to adjust the tension of the X, Y or Z axes by tightening or loosening them. Having a printer where the tension belt is easy to access and adjust will make life a lot easier. Otherwise, you will have to figure out how to remove specific components in order to access the tension belt, which require time and intricate knowledge of the printer hardware. Plus, if you aren’t able to put everything back in place the right away, it will cause further issues.
