Clayroof 3D Pen, 3D Doodler, Drawing Printing Printer Pen

I seriously do not understand how this pen could get such high ratings. I'm giving it three stars because it is just okay; meaning it disperses filament at the right temperature and lets me reuse my remnants of other filaments from my 3D printer. I got this pen to make minor repairs to 3D models I print and to make stronger bounds between parts if needed.My main gripe is the position of the buttons to operate the pen.I guess that complaint would be followed by the poorly written and hard to read (because the font is so small in some places I needed a magnifying glass to read it).Lastly the pen is too hard to control. There seems to be no auto feed, so you have to continually press the feed button, but the feed button doesn't always want to feed and when it does it is hard to stop. Add the fact that the button to change modes is on the exact opposite side of the pen from the feed button making it almost impossible to press feed without accidentally changing the mode from low, medium to high.Then to top it all off, it clogged half way through a project.I have to wonder what genius thought placing the buttons to change mode and feed the pen at exactly the same location. I mean it doesn't take a rocket scientist to predict that some one is accidentally going to press the mode button while trying to grip the pen to press the feed.I also can't believe that China is being so cheap they refused to hire professional English speaking writers. I mean really, half the instructions make no sense (when you can read them).But, you get what you pay for. I'm shopping around for a different one as soon as I can afford it. This one will do, but I wouldn't recommend it to anyone.

My daughter Naomi loves it! is the best gift I've bought for her, and we spent more time together creating new sculptures. The pen really works great and its so easy to use, the design template for the glasses was a blessing and the seller sent us more templates after :) also, the packaging is really good and the build quality of the pen is better than most pens I've used. Initially I bought it for my daughter but I found myself very fascinated, I really like drawing in 3d and it became easier after I saw the youtube tutorials provided by the seller.

So I bought this a few months ago and had no issues at the start. After testing the limits and playing around with different filaments, I found one flaw. The pen never clogged, but the motor that pulls the filament in stopped for some unknown reason. Now initially I was a bit upset about the issue, but after contacting the seller, I fortunate enough to receive a replacement for the damaged pen. After using the replacement, no issues were found. Maybe I received a faulty pen but got a replacement in return. All in all, the pen works great and the customer service was quick and astounding.

I bought 2 boxes for my kids. They both loved them, so did my wife and I.The packaging deserves a credit. It is colorful and stylish. Each of the 40 colors is put in a separate vacuum sealed bag with silica gel and 2 cord ties holding them together. Each pack is marked with color, type, and size of the filament. Really impressive.The colors are vibrant and stay true when printed. Filaments work perfectly with my kids` pens. Nice flow, no jams at all. Feeds into the pen without any issues. Very satisfied so far. Kids already printed a cute guitar.I will definitely be purchasing more from them again.

Product came exactly as advertised. Really cool thing I got for my 8 year old on his birthday. He loves it, but so does my wife and I. Came with stencils as promised all packaged in a zipper type bag that makes it easy to keep it all together. Plus, got a followup E-mail by the seller making sure everything was good with the order. That's nice to add to overall experience.

This is our second pen, being a different brand than the last. They just don't last more than a couple months.

It is easy to operate and that the youtube video was helpful. Also it is possible to draw in 3D, but it requires patience and practice. -KL

This pen is great. My son loves it so much. He is constantly wanting to make new things. The company is awesome and have a youtube channel to help with learning how to use it. And they also send you more stencils electronically, so you have lots of help creating amazing things.
