Makeraser is multitool designed specially for 3d printing. it has acetone tool for gluing, repair and finishing and metal spatula / blade to remove printouts from the printbed. Nice product and nice review by Zatopa.com.



Interesting part is that it seams to increase the strength of acetone treated part since it melts together outside layers.
I hope I'll have an interview with Makeraser crew soon, so stay tuned ...

Great review video of MendelMax 2.0 by ZennmasterM.

MendelMax 2.0 description from RepRap wiki:

The new MendelMax 2 is a complete reinvention of the MendelMax. It makes the MendelMax faster to build, easier to source and even better looking than before.

Design
The MendelMax 2 includes a completely redesigned frame, made from aluminum extrusions and primarily flat plates. These plates can be cut from aluminum, printed, laser cut from plastic, or hand cut with a scroll saw or a coping saw (making this arguably the most accessible DIY reprap ever). A hand cut MendelMax 2 will virtually function identically to a custom machined one. There is no longer a reason to see your hand built machine as merely a means to an end.
Triangles are a smart choice for the gantry, both functionally and aesthetically. From a design standpoint, I wanted the MendelMax to still be visibly a Mendel descendent, while not letting the shape get in the way of improvements. By switching to a right-triangle design, the MendelMax 2.0 gains ~50mm more z-axis movement (the exact amount will depend on your extruder choice). The new design results in a very open, unobstructed print area.

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.

It looks like PC case aimed at gamers / PC modders that has a 3d printer in it. Beside great design it has no other innovative features and there are no tests or videos of it working. It also uses some custom software and some sort of custom filament cartridges. I'm all for diversity, competition and options and like it's design so hopefully we will see more of it in the future.

The AluhotendV4 is specifically designed for general use high resolution printing with PLA , ABS and NYLON, The nozzle size is 0.3mm and the hotend comes assembled and sealed ready for use at temperatures up to 245 C. It features a PTFE liner for a high degree of reliability. This hot end requires a fan blowing on the heat sink for proper operation.

Package contains:

1 x Aluhotend- 1.75 mm or 3 mm

1 x 100k thermistor (selection 10 in Marlin)

1 x 12v Heater Cartridge

1 x M4 Grubscrew

Practical experience in printing Ulimaker Bowden clamp upgrade with Colorfabb PLA / PHA and XT clear materials.
