Super for home use

I'm talking about a second-hand printer (300h print ) repaired by me with parts coming out of service in 10 days. The components are dedicated and I preferred to exchange with the original. Everything was 30% more expensive than any compatible one. If anyone needs details they can do a more complete tutorial. If he had hotbed and self-calibration would be very good. As 3D design software I work with SolidWorks exporting in .stl format. I am from Romania.

Great entry level

Old at this point but the price has dropped and it has sales frequently! Very easy to use and fairly consistent. No heated bed and the acrylic plate is not always cooperative. If your model wont stick, wipe it down with a micro fiber cloth and be careful of your finger oils! I really enjoy it but think there are probably better buys considering it's age! The slicing software is not as bad as others imply however it is proprietary AF. Simply3D does function with it though so options options!

OH and generic filament wont alllways fit but generally will. Just beware!

Dremel 3D20

The Dremel 3D20 only supports the .3drem file format, witch limits the software products that can be used with it.

The build platform needs to be covered in their build tape to protect the plastic build surface, and provide a surface that the melted plastic will adhere to. The build tape  is expensive, can only be reused a few times, and does not work well. After having it cause several build failures, I began looking for alternatives. Painter's tape and plastic food wrap both had issues, but were better than Dremel's build tape. 

Several builds just stopped half way through. The printer would be working just fine. Then it would reboot without any error message or explanation.

All in all, the Dremel 3D20 could be a great entry-level printer. But, there are some problems for Dremel  to work out first.

The starter kit

For a newbie into 3d print, it's a good start, this one was made for education purposes, if you plan to use for specific or more techs project : pass your way, i'll try to go deeper with slicer like cura and craftware to build support, but it dosen't make it everytime.

Good out of the box, but limited ...

Very good results 'out of the box" with plain PLA. Adjusting platform takes very secure skills. Sometimes filament gets stuck in nozzle / print head (when it gets "old" and "brittle"), but only two inbus screws need to be unscrewed to solve any problems there ... Also replaced the nozzle a few times already .. Advanced printing gives sometimes problems with non-sticking to the platform. Hight adjustment and/or renewal of platform sticker will help, but you should want a heated bed, also for printing flex and other materials ..  (3D45 was not invented when i bought this 3D20, otherwise i would go for that one ... I probibly will be making my own adjustments to the 3D20 with an universal separate heated bed soon ..

Great 3D Printer

I had this printer up and running within minutes of it arriving. It is super easy to use and you won't run into many issues with it. The only thing that bugs me is the filament cost - each spool of Dremel PLA is $30 for half a kilogram, which is several times more than the industry standard. If you want to lower your costs while keeping the same quality, switch to Hatchbox. And if you want to increase quality while keeping the same (or slightly lower) cost, switch to Polyalchemy, ProtoPasta, ColorFabb, etc. You will have to print a separate spool holder, since the one attached to the machine doesn't work with other spools.
