The M2 is the 3rd generation 3D printer offered by MakerGear. One thing we've learned along the way is that better parts make better 3D printers. With M2 the goal was to create a high-quality and reliable 3D printer while keeping the price reasonable and still provide robust customer service.
A desktop 3D printer is a precision machine. Layer heights (the thickness of an individual printed layer) are measured in small fractions of a millimeter. Typical layer heights are between 0.3mm and 0.1mm but sometimes go below 0.05mm. A millimeter is about the thickness of 10 sheets of ordinary laser printer paper. That means the thickness of a single printed layer is normally between 1 and 3 sheets of paper. Hold up a piece of paper and take a careful look at the edge. It is really thin but on an M2 you can print layers even thinner than a single sheet of paper!!
Keep this in mind when you are reading the specifications for a 3D printer. A printer with a flimsy frame or low tolerance parts will frequently get out of alignment and require near constant tweaking to produce quality prints. We used plywood for the frame of the M1. Plywood was OK but each sheet of plywood varied a little (or a lot) and was also subject to environmental conditions like humidity, heat and cold. For the M2 we switched to a fabricated steel frame. The M2 frame is extremely rigid, not subject to environmental conditions like plywood and the black powder-coating looks great! It is more work to manufacture steel frames but it is well worth it. The choice between a steel frame and a plywood frame is really no choice!
Mounted on the steel M2 frame are structural components precision machined from aluminum tooling plate (precision machined cast aluminum prized for the finish, flatness and stability). True linear motion components are then mounted on these precision parts. The combination of true linear components, precision machined parts and a rigid frame is a 3D printer that is ready to print out of the box and for a long time to come with minimal maintenance. A linear rail (visible on the left part in the following photo) consists of a precision machined stainless steel rail that is fastened to the aluminum plate. The carriage contains circulating ball bearings designed for reliable, low-maintenance and accurate linear motion. The rigid M2 frame plus the machined parts plus the true linear components plus the MakerGear extruder = Great Prints!!
The plastic handle, extruder mount, spool holder and other plastic parts used on M2 are all printed in-house on production M2 machines. The M2 ships with everything you need to print. The power supplies work in the US and internationally (local plug is included). If you are placing an international order or you will be using the M2 for production - we recommend ordering an extra hot-end/filament drive. We also recommend using Creator with your M2 though the open-source RepRap tool chain will also work. An optional LCD controller that allows you to use your M2 without connecting to a PC is also available.
M2 performance specifications:
- Z resolution: 0.1mm to 0.25mm recommend. User selectable down to 0.01mm
- Minimum Z resolution: 0.0025mm
- Minimum X/Y positioning: 0.01mm
- Nozzle orifice diameter: 0.35mm (0.43mm typical extrusion diameter)
- Maximum X/Y movement: 450mm/s
- Typical print speeds: 80 - 200mm/s
- Typical travel rate: 100 - 250mm/s
- Extruder extrusion speed (manual): 300mm/min. Actual speed varies based on the object print settings
- M2 weight: ~28 lbs (12.7kg)
These performance specifications have been provided for your reference. However, other factors such as machine construction, acceleration rate and nature of the object being printed need to factored in in order to really understand machine performance.
The M2 kit is the right choice (vs. an assembled M2) if you really enjoy the assembly process. You'll need intermediate levels of mechanical and technical skills to get it assembled. The wiring is fully crimped but you'll need to route and connect it. You should be comfortable using basic tools (wrench, pliers, hex keys, etc.), working with electronics, routing wires and plugging in connectors. Go through the M2 assembly instructions to see exactly what is involved. If the assembly process is not something that you enjoy then the assembled M2 is the right choice.
Note: The M2 does not have a power switch on the machine. We recommend that you plug the machine into a power strip and use the switch on the power strip to turn your machine on and off. The extruder and electronics fans turn on when the machine is powered.
The M2 was designed and is assembled by MakerGear personnel at our location in NE Ohio (Beachwood). The steel frame, machined aluminum components, machined extruder parts and the wiring harness are all manufactured and/or assembled in NE Ohio. Other components are purchased off-the-shelf or made to MakerGear specifications by various US and foreign suppliers.
*Please understand that these kits consist of many parts and require a complex supply chain. We do our best to meet the shipping estimates listed above but sometimes shipments are delayed, damaged, lost or we receive wrong or unacceptable parts. If a crucial component is delayed, we may not be able to meet the estimated shipping date. If there is a delay, you will be informed via email so please be sure you provide a correct/working email address with your order. If you do not receive an order confirmation within 24 hours, please let us know.
**M2 kits have a six-month warranty on defective parts. Some of the kit parts are individually tested but problems may emerge once the machine is assembled. For international orders, the buyer is responsible for shipping for replacement parts. Replacement parts for kits and assembled machines are typically shipped by USPS Priority but other methods may be used.
