User Experience of the Creality CR-10 V3

The CR-10 V3 comes partly assembled so, putting it together is fairly easy. For experienced DIYers, setup should take no longer than 45 minutes. Just make sure you tighten the numerous bolts properly.

There is no automatic bed leveling out of the box. You’ll have to do it yourself manually. However, Creality did leave a space for a BL-Touch sensor if the user wants to upgrade.

The firmware is up to scratch, and all the new features work well. However, the new LCD interface is a bit of a disappointment. The scroll wheel can seem off at times, especially with new printers sporting touchscreens, but overall operation isn’t too bad.

When it comes to printing, there are no complaints with the CR-10. The print bed works well and distributes the heat evenly to avoid warping.

It also heats up fast, and prints pop off cleanly with a smooth bottom finish.

The direct drive extruder also produces high-quality prints consistently without any of the issues seen in budget printers. The printing operation is also quiet thanks to the new motherboard.

Pros of the Creality CR-10 V3

  • Easy to assembly and operate
  • Quick heating for faster printing
  • Parts pop of the print bed after cooling
  • Great customer service with Comgrow
  • Amazing value compared to other 3D printers out there

Users that want more out of the firmware can easily upgrade or modify it.

The MK3S+ has both a USB A port and SD card ports for connectivity. For slicing and preparing prints, Prusa includes their PrusaSlicer software in the box. However, users can still use Cura if they want to.

The print bed of the MK3S+ is a removable PEI-coated magnetic steel bed. The steel bed can reach temperatures of up to 120oC. At temperatures like this, it can print high-strength filaments like ABS.

The steel build plate performs exceptionally well. There is excellent first layer adhesion, and you can easily remove the plate and bend it to pop the finished print off.

The newly redesigned extruder produces consistently good prints. Not only can it handle a wide range of materials, but it can also sustain a high flow rate of filament. All this makes the Prusa MK3S+ the premier choice for printing gun frames and other accessories.

User Experience of the Prusa i3 MK3S+

Depending on how much stress you like, the assembly of the Prusa MK3S+ can either be easy or hard. For a slightly higher price, Prusa can ship a fully assembled printer to your doorstep.

However, if you like to do a bit of DIY, you can order the kit version and spend some hours putting it together.

The good news is once you assemble it, the rest of the setup work is easy to do. The MK3S+ has both automatic filament loading and bed leveling. So, getting the printer ready isn’t much of a hassle.

The printer’s LCD is a bit outdated, but it gets the job done. Prusa’s PrusaSlicer is also a competent software program. With it, you can access custom profiles for the MK3S+ that are absent in other slicers.

Once printing starts, the MK3S+ shows its worth, and its quality shines through. The MK3S+ produces excellent high-quality models rapidly and consistently without any hassle.

Its operation is also whisper-quiet thanks to its new motherboard. You can barely hear it printing away, even if you’re in the same room with it.

Tips for Printing Gun Lowers, Receivers, and Frames

Before you start printing, there are a few things you need to know to avoid any trouble. Let’s look at them:

Check Local Regulations First

As I mentioned earlier in the article, 3D printing gun is still a bit of a legal gray area. Some states have legislation regulating the creation and the use of 3D printed firearm accessories.

To avoid trouble with the authorities, make sure you are well-versed in these regulations before you start printing.

Use the Appropriate Filament

Firearms, in general, experience high forces and stress during their service life. The same thing applies to 3D printed guns.

To get a long-lasting firearm and to avoid accidents resulting from misfiring make, sure you use a high-strength filament. Filaments like ABS and PETG can provide the type of strength required for this operation.

Always Take Finishing Seriously

Guns are delicate machinery that work on the tightest of margins. Even slight irregularities in their mechanism can lead to jamming.

To avoid this, make sure all the parts irregularities are appropriately taken care of before you put it to use. You can read more about finishing 3D prints here.

So, good luck and happy printing.
