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.

Specification

Size: 15cm(W) x 15cm(D) x 22cm(H) (excl. filament holder)
Printed size : 8cm x 8cm x 8cm
1.75mm filament / 0.4mm hotend

Is it just me, or does this read like an advertisement more than a "hey, look at my printer!" post?

I don't know why they'd think an ad for something like this on this forum would get too much traction. Most of the people here already own one or more larger printers, and could easily make something like the V3D, the Tantilus, or Kossels if they needed additional printers. It's dirt cheap, but then, you deal with a support team (if they have one) without a guarantee they know english, they're using what seems like undersized components for any sort of speed, and it appears that it has no bed heating provisions, nor does it seem like they would use an actual E3D hotend, as that would eat almost 20% of the printer cost, if not more. They also don't mention including a 12V PSU for it, as it looks to take an external brick.

[mhackney]

It's an ad but it is open source so you build your own.

[bot]

Yeah, kinda "ad-y" but since it's open source, we should let it slide. They're sharing info for free. One of the huge hurdles of our economy is the hoarding of information -- anyone willing to share it gets a pass in my book.

[mhackney]

I agree.

[Eaglezsoar]

I am also in agreement but only because it is open source.

[nitewatchman]

There is a lot of traffic on this printer in RCHobbies.

Nicest thing to say is that these appear to be ongoing projects.

A 1 day old member with only one post? No... Never happens.

[derzaubererer]

this actually looks quite easy to build:)

[TheIrishScion]

I must confess, the idea of a micro-printer I could sit on a desk at the office is very _very_ appealing.

Awesome quality!

As far as I know, this particular model has been discontinued and not available through Hobby King. There might be other sources. There is apparently a tinyboy2 Indigogo project.
