Makerarm: milling, lase cut, assembled and printed in 3D

A jack of all trades of a machine tool studied finance willing fans on Kickstarter - it sees them with their fancy white trim more like a precision laboratory equipment. What is not entirely wrong.

Actually, the idea of ​​multi-function machines is so obvious: If you have ever built a mechanically complex three-dimensional positioning of a 3D printer, then why not equal to provide a replaceable head, with which the device can be retrofitted to CNC mill? As a rule, however, such 3D printing and milling station wagon stuck in a housing that encloses the space completely. This is different when Makerarm, for the currently financing action on the kick starter crowdfunding platform runs: This device consists essentially of a free-standing column can rotate about its base and a boom which travels up or down. The boom has a further pivot halfway.

The Makerarm should be able to place the interchangeable tool head within a semicircle of nearly 40 centimeters radius as desired, the amount usable is 25 centimeters. The design of the arm vaguely reminiscent of that of 3D printing and laser cutting machine LumiPocket LT Lumi Industries. The company Makerarm promises an absolute positioning accuracy of 0.1 millimeters, the relative reproducibility of an item should be even less than 0.05 millimeters. The tool head can be hard up to one kilogram - the system should be shown here also DIY projects open. A second joint in the bracket for additional freedom of movement can be retrofitted.

The manufacturer wants to offer a number of different tools for the Makerarm so that the machine printed approximately selectively by the methods stereo or FDM in 3D, assemble circuit boards, put solder pads, tighten the screws, move things, cut with a laser or a knife or decorate cakes can. automatic adjustment should belong to the position of the working surface of the refinements, also making several arms makers can work together - built-in Wi-Fi provides the communication flow. The work orders to configure in a specially created software, in addition, each purchaser of a Makerarms is to receive a commercially viable one-year license for the CAD / CAM cloud service Autodesk fusion 360th

Makerarm still has not reached its funding target of just under $ 350,000, but the campaign will run for one month. For those who still want to get in, unfortunately, does not get early bird copy more. The most inexpensive option are in 1400 US dollars for an arm and a tool head of choice (shipping to Germany costs an additional $ 105). Who'd rather have the complete package with all tool heads, pays 2,200 dollars. By comparison, a sophisticated operative FDM 3D printer costs a lot similar.

If this is too expensive, might give a look at Dobot, a 4-axis robot arm in a classic design and Arduino-based, which is also at Kickstarter in the race.

Dobot be financing target has already been achieved, but it is still in limited quantities for $ 450 (including worldwide shipping) for the maker and hacker version of the arm opt without accessories. The unlimited full equipment with various tools and sensors will cost 800 US dollars.(PEK)
