The iModela IM-01 "3D Printer"

We've been reading a ton of posts from various online services talking about Japan-based Roland's new "iModela 3D Printer". This fully assembled device is able to produce 3D objects upon command and retails for under USD$1000. The iModela IM-01 comes with software to design your objects, a travel case and there's even an online community to discuss your iModela activities. 

 

But we noticed something. 

 

It's not a 3D printer. 

 

It's an inexpensive simplified 3D CNC Mill. It can cut a block of wax, balsa wood or plastic and carve it into arbitrary shapes (so long as the geometry permits the milling process to work). The iModela can accept a wide variety of common milling tools from model shops. 

 

Why isn't it a 3D printer? Well, for one thing it uses "Subtractive Manufacturing", the taking-away of material to reveal the final object, while 3D printing, as it has come to be known, uses "Additive Manufacturing", where material is gradually added to form the final object. 

 

While we're certain this is a fine hobby mill, we're wondering about the public's understanding of 3D Printing technology. How did so many blogs immediately mistake this mill for a 3D printer? At no point on Roland's web page does it claim to be a 3D printer. Instead, Roland explicitly states in its headline no less, that it's an "Affordable 3D Hobby Mill".

 

Nevertheless, it does produce 3D objects, as do many other technologies. But we're here to talk about 3D printing.

Modular Desktop CNC Machine Needs Your Help

AJ Quick's new Kickstarter project is an inexpensive but highly capable desktop CNC machine. The device was designed by University of Minnesota Mechanical Engineering students specifically for use by home operators or perhaps even light business use. While the original prototype was quite successful, they want to take the concept to the next level. To do so, they've redesigned the machine for home use: it' affordable and will easily fit in your workshop. However, to get it off the ground they need your help. 

 

They're seeking assistance via Kickstarter, the venture-capital-in-the-cloud service that has proven very successful. By contributing to their project, you'll be able to enjoy various levels of awards depending on the amount of your contribution. The highest contribution levels ensure you'll receive a kit so you can build your own desktop CNC. 

 

The device is quite capable, including a cutting area of 18"x12" (46x30cm), a very rigid frame and:

 

... hundreds of dollars worth of shafts, bushings, bearings and professional leadscrews to get it moving! In fact, 80% of the machines’ cost is in these expensive linear motion components. To put it simply, this machine is awesome!

 

As of this writing, they're already over their contribution goal - but if you're interested in supporting them, please take a look before February 15, 2011 when the funding round closes.

StudioMill

It's not a 3D Printer, but it is a very capable 5-axis CNC machine; the StudioMill, sold by A1 Technologies. Directed at academic institutions, the device will enable students to get their hands on serious CNC technology:

 

Studiomill is supplied as a complete educational CAD CAM solution with the purpose built PathingCNC software which is used to simulate and control the modelling process. 

 

The PathingCNC software is intuitive and easy to learn and allows you to view and manipulate your CAD model in a virtual tooling environment and quickly and easily tailor the modelling process to suit your requirements. The software allows the more advanced user to exercise complete control over the modelling process, but also provides a degree of assistance to the novice user.

 

What makes this machine appropriate for educational use, other than the price? There's a number of specific features:

 

• Windows on all sides enable viewing of operations by students
• Easy to use and maintain
• Safety features
• Five-axis function for teaching production machining processes 

 

Studiomill can perform very fine finishing, up to 0.05mm resolution, and is capable of handling a wide variety of materials in its 160x220mm work area. Available now from A1 Technologies, starting prices at £6,000 (USD$9300).

A1's Subtractive UNIMAT Series

A1 Technology, sellers of a variety of additive 3D equipment including the low-cost BfB 3000 3D printer and RapMan 3D printer has introduced an entirely new line of products: The UNIMAT series, a collection of subtractive manufacturing tools. 

 

The premise is UNIMAT's extremely low pricing and modular design that should enable the technology to get into the hands of many more people, particularly educational institutions. How accessible is it? If you were to purchase the UNIMAT 1 Classic package, which includes a jigsaw, drill press, milling machine (both horizontal and vertical) and a metal lathe - all for only £399 (approx. USD$580). That's accessible!

 

The series includes "PowerLine" system that permits expandability by adding modules to provide different functions. The "MetalLine" package provides precision tools for highly accurate and professional use, and the CNC package is of course, a CNC machine.

 

Pricing in Pounds Sterling is as follows:  

 

• Playmat £99
• Unimat 1 Basic £199
• Unimat 1 Classic £399
• Styrocut 3D £149
• Unimat MetalLine Classic £699
• Unimat Power MetalLine £2,450
• Unimat CNC line £1,990

DIYLILCNC

The DIYLILCNC is a do-it-yourself CNC machine. Much like open source 3D printer designs, this one is instead for a CNC machine. This one can be built for approximately USD$700. From the site:

 

Plans and instructions for building the DIYLILCNC are distributed freely and intended for wide distribution and modification with few restrictions. The plans are formatted to facilitate easy fabrication, especially for beginners. The DIYLILCNC can be built by an individual, a student group, or a class. Besides being immensely fun, building the DIY LIL CNC is a great way to learn about motion control and CAD/CAM/CAE.

 

The 2MB download includes a 65 page detailed manual taking you through all aspects of the machine's assembly and software setup, as well as the design files for all the laser-cut components. We're wondering if Ponoko has this one available on their service?
