What is TinyBoy?

TinyBoy - Open Design 3D Printer for Student and kids
A small , easy to build , affordable machine

TinyBoy is an open design 3D printer. The size is just 15 x 15 x 21cm , even smaller than most of the 2D paper printer. Therefore , it fit for regular computer desk. The design aims as an entry-level machine for student and newbie to learn 3D modeling technology and train for creative thinking.

Less is more

The maximum size of printed object is 8 x 8 x 8cm , which is relatively small than many other 3D printer. However, it is already large enough for making things like figure and toy.

The gain from the trade off is the cost down of material and maintenance. Take out components for making large printed object , the design become simple and lean. The core material is acrylic sheet and connected by metal screw. Therefore , the cost of material and building can be minimized.

Easy to build / Learning by making

The process of making has the opportunity to transform education by inviting students to be something other than consumers of education. They can be maker of anything , moving from being directed to self-directed through the process.

Tinyboy is designed for easy to build. The assemble from kit can be done by just using a screw driver. We wish student can make their own machine. Then they become a pioneer whose may make another one for other people. So that the use of 3D printer can be spread out to more student.

The case of TinyBoy uses acrylic plane as the main material. Individual parts can be made by using cutter laser. Therefore, the manufacturing process is easy once you have a laser cutter. In fact , the price of an A5 laser cutter can be as cheap as USD $400. That make the cost of small amount production be reasonably low.

Any idea when the latest will be on GitHub? Looking forward to the new design!

Also, you mention laser cutters that can be found for ~$400. Can these cut 3mm acrylic? I've seen a lot of engravers at this price, but not cutters. I would be interested in a link.

Thanks

According to Indigogo they should be in the "producing" phase. Backers are supposed to get their V2s in March. But I'm not sure if they had to push that date or if everything is according to plans.

I have not a lot of experience with lasers, but the cheap $400 lasers usually are just engravers with a simple laser diode. To reliably cut material you need a CO2 laser with at least 40 W. The last laser I used on campus to cut acrylic was a 60 W version.

im looking to make one, where can I get part lists and assembly videos?

You can find most details on the old version (new one is coming soon) on GitHub: https://github.com/HKCOTA/TinyBoy/blob/master/bom_list.md

New Firmware is out.
We merged our setting to Marlin 1.1.0-RC3

https://github.com/TinyBoy3D/Marlin/tree/tinyboy-1.3.2b

Too bad I cant find fully assembled units.... And I cant really navigate around their website so.... Looks like I wont be buying one anytime soon. Anyone know where to purchase them (In stock not back ordered)?

Which engines you have installed

TinyBoy 2 is now on Indiegogo.

https://www.indiegogo.com/projects/tinyboy-2-3d-printer-for-education/

Printing larger and faster but keeping almost the same size of the old version.

Here is the printing demo of the TinyBoy 2.

to make this cheaper and more available to students, young makers and makers who don't have allot of $$ you should consider making a version that uses servo motors (like these http://www.hobbyking.com/hobbyking/store/uh_viewitem.asp?idproduct=663&aff=141728 ) so the resolution will be buffed down, but it will be much more affordable.

The BOM I could get by opening the github files using Inventor.
The belt is using 4mm MX, length is about 47cm.
The control board is using MKS.

Here are the videos from the Youtube:

can you post a vidio of it printing? then what you need to is post stl files of the box fo it so it can be printed.

Are you going to make kits available? If so, this looks like a great little project. I know I would be interested in getting one in a complete kit.

Should not have, even BOM can not find ...
