Another great review by Barnacules of Ultimaker 2. He goes trough unboxing, setup, calibration, leveling and first printing. His machine came delivered with on extruder fan broken. The leveling process seems easy with adjustment screws on the bottom of the print bed.

From video description:

The Ultimaker 2
To operate the Ultimaker 2 you don't need any specific technical knowledge. Every part has been redesigned to create one of the highest performing 3D printer available on the market, but also a very reliable one.

Ultimaker 2 specifications
Easy to use and reliable
Designed for non-expert and expert
Larger build envelope
Heated bed
Low cost material
Open source
Just like the Original the Ultimaker 2 will remain open source. We dare to share our knowledge because we believe we can achieve even more when working together.
Easy to use and reliable
To operate the Ultimaker 2 you don't need any specific technological knowledge. With its 49 decibel it's a quiet machine. Because the electronics are bundled the Ultimaker 2 is stable and reliable. With its nice design the Ultimaker 2 is suitable in any working or living interior.
Designed for non-expert and expert
We've made the Ultimaker 2 to be as easy as possible. You don't need to have a huge technological background to understand our printer. At the same time we've developed the printer in a way that it's still interesting for experts to work and create with.
Larger build ratio
We've managed to get an even better print-to-size ratio. This means the printer size has remained the same, and the print envelope became bigger.
Low cost material
Beside the fact that the Ultimaker doesn't use a lot of power, the material you use to print is also low cost. This makes the use of an Ultimaker very affordable.

There is no detailed information HOW he did it, but Daniel Widrig managed to 3d print a chair by using a mixture of plaster and sugar with sake. It was commissioned as part of an art exhibition.

Pawel Dobrowolski is working on extruder made from plywood. He made first progress by making plywood gears.
Pawel later commented on this post that this extruder is based on yruds/yegah design which is popular in Poland  and it is a part of bigger open source project called BYQ 3d printer made fully in plywood .

Developed by Dr. Kee Moon and Jeremiah Cox, the device seeks to better conform to the way the body moved before an accident or injury occurred. Rather than rigidly control the movements of the leg, their device nudges - or kicks - the leg to begin natural physical motion. In the future, the bionic leg will further tie in with the brain to better adapt to former muscle memory, allowing the patient to better achieve their previous and unique way of walking or moving.

Carbon fiber 3d printing was the technology many people were waiting for. We could finaly get very durable and strong printed objects.

Brilliant ideas need brilliant materials.
Designed to overcome the strength limitations of other 3D printed materials, the MarkForged Mark One 3D printer is the world’s first 3D printer designed to print composite materials. Now you can print parts, tooling, and fixtures with a higher strength-to-weight ratio than 6061-T6 Aluminum.

Gregory Mark, the President of MarkFoged, also co-owns Aeromation, another carbon high technology company responsible for manufacturing computer controlled race car wings. The wings are typically made out of carbon fiber because of it’s high durability, strength and low weight. They discovered that it is quite a challenging task to manufacture parts out of carbon fiber, because of the time needed and high expense in laying the fiber down piece by piece in the production process. That’s what motivated the development of 3D printer which could simply print the carbon material.

We are waiting for more details and print results!

Mark One is produced by Mark Forged:

Now, after the initial hype, we can say that there are many uncertainties about the technology behind this printer.

• carbon filament and various carbon fiber technologies have been used in 3d printers before, but as far as I know, no machine has been designed specially for the carbon technology and this would be the first desktop / prosumer printer
• it is unknown how exactly Mark One prints with carbon fiber: is it a new "special" filament where carbon is mixed in thermoplastics or is it some other technology 

Screenshot of Mark One webpage showing that the carbon fiber material is 20 times stiffer then ABS and 5 times stronger

Mark One is multimaterial machine that can print objects with two materials with different combinations of core, shell and structural honeycomb

Technology of 3d scanners is exploding together with the developments in 3d printing machines. Fuel3d is one of more high-end scanner that is much expected to reach the market.

They released the final design of production unit:































Here is the video presentation of Fuel3d and usage cases:




Here is what company claims are main advantages of Fuel3d against competitor technologies:

• Turntable: The most basic and lowest cost 3D scanning systems use laser point or line projection onto an object positioned and rotated on a turntable. Prices range from a few hundred dollars up to low thousands. As a handheld solution, Fuel3D holds a significant flexibility advantage over these systems, as they are fixed position and the object being scanned is limited by turntable size.
• Sweeping laser line: To enable scanning of larger objects, scanners are available that project a laser line, which sweeps across a stationary subject. With a few exceptions, prices for these technologies are typically in the $20,000 – $50,000 range. Fuel3D has a very strong price advantage over all these systems, with the added benefit of handheld flexibility and color capture.
• Hand-held: 3D scanning systems have been developed to enable maximum scan flexibility for working around objects of almost any shape and size. Prices of hand-held solutions are now as low as $15,000 – $30,000. In addition to Fuel3D being much less expensive, we are not aware of any of these handheld systems that collect color data in addition to 3D geometry.
• Microsoft Kinect: Some low-cost handheld scanning solutions are being developed using the Microsoft Kinect platform. These systems are typically quite low-resolution resolution, so while they are good for capturing environments, they do not have the data precision or resolution for detailed object capture like Fuel3D.

The Fuel3D scanner is priced from 1,250 USD without shipping costs or taxes. Estimated shipping start is in September of 2014.

Adobe is joining the ranks of corporations that got into 3d printing field. Photoshop cc update 14.2 bringe many features for 3d model print preparation and support for several 3d printers.
Support for directly printing from Photoshop CC to 3D Systems Cube, MakerBot Replicator 2, MakerBot Replicator 2x and Zcorp Full Color is built in, as is the ability to export an STL file.
It can work with several 3d print object properties, such as:

• Printer Volume – This will show the measurement that the model is shown in (the numbers marked in Blue are shown in the chosen measurement).
• Detail Level – Minimum size of features that can be printed.
• Show Printer Volume Overlay – This is the cage around the model, the cage is generated and shows the maximum capacity of the print chamber in the 3D printer
• Printer Volume – The size of the print chamber in the measurements that have been specified above.
• Scene Volume – This is the size of the physical cage around the model inside Photoshop CC, this can be modified using the numbers, or a fast way to scale the model to the cage is it click the button marked “Scale to print volume”.
• Surface Details – Photoshop CC will use the Bumps, normal maps and opacity to enhance the final detail.
• Support Structures – Photoshop CC will generate the supports and raft for the output preview.

For Photoshop CC to be able to print the model, it will automate the following tasks for you, i.e :-

• Wall Thickness – The model is hollow, the walls will need to be adjusted to make sure the minimum wall thickness is achieved, in accordance to the selected printer specification.
• Repair the model – The Model may not be, what’s know as “Water tight”, which means it may have holes in it, or normals that are the wrong way around (there are other elements here as well), that will cause the print to not properly.
• Create scaffolding – The elements that we explained earlier that are ‘floating’ need to be supported during the print.
