“ECHO” machine is a multi color 3D printer has been designed using of the addictive manufacturing techniques regarding the rapid prototyping process. This is technique known as (Fused Deposition Modeling – FDM). First, and like all 3D printer machines, the CAD file of the part which is wanted to be printed to a 3D object is exported with (STL) extension. This extension allows the 3D printer program to view the part as accumulative geometric surfaces rather like the surfaces resulted in (Finite Element Analysis – FEA). Using the 3D printer program, the part can be converted to many tiny slices and then these slices are sent in successive method to the 3D printer machine so the part will be built slice over slice until getting the full 3D built part at the process end, as a result this built part and the modeled part in the CAD program will be alike. This technique, for the purpose of building implement, is count on melting a thermal polymer which pours after positional melting form the actuator head nozzle. The actuator head traces the cross section of the processed slice and builds according to it until the full completely of the slice section. The procedure is repeated many times to complete the part building. This technique uses another thermal polymer as a supporting material to fill all part gaps and to support the built part body is case of balance adjusting during the building process. After the building end, the support material is got rid of and we will get a part or a product built from just the building material.
In this printer, the thermal polymer (Acrylonitrile butadiene styrene – ABS) is used, this plastic polymer melts in a Celsius degree between (180 – 220) degrees, and it’s provided in the markets as a filaments coiled around a roll, the used filament diameter is (1.75mm), ABS filaments substance has a color vary (in this machine the blue, red, yellow ones are used as a building material).
Regarding the supporting material, the used thermal polymer is (Polyvinyl acetate – PVA), this plastic polymer melts in a Celsius degree between (180 – 220) degrees, and it’s provided in the markets as a filaments coiled around a roll, the used filament diameter is (1.75mm) and it’s often found in white color (the roll located at the right side of the machine). The important specification for this material is the ability to dissolving into the water. Consequently, after building the part, it’s enough to submerge it into the water and so the supporting material will dissolve into the water and the building material will remain.
Both of building and supporting material are provided to the actuator head nozzle by means of a feeding mechanism which consists of a feeder for the purpose of pulling in the plastic filament from the roll and then guiding it into a canal ended with the melting chamber which is in touch with a ceramic heater (40 watt). And thus, the material is melted and poured out through the nozzle which has an orifice with diameter of (0.5mm). The feeding mechanism includes a cooler made from aluminium substance to prevent the heat from transferring toward the top. The number of actuator heads and feeders is four (three actuator heads for building and the remained one is for supporting). The heat exchange can be done for the four coolers by two fans behind the actuator heads.
Regarding the Mechanical Design Side, this machine has three axes (X,Y,Z). it depends for moving the actuator head along the (Y) axes, which it represents the machine gantry, on a motion method consists of a stepper motor and high accuracy synchronous pulleys and belt. The motion of the axis (Y) vertically along the axis (Z) is achieved by means of a pair of ball screws located at the two sides of the machine. According to the (X) axis, it’s the motion of the work table to front or back using stepper motor and synchronous pulleys and belt. In all axes, guiding mechanisms are used, they consist of rails with (V) shape and over them wheels with (V) shaped grooves are moving on them. In the (X) axis, in addition of the previous guiding mechanism there is a cylinder guider “Ball Spline” which is used to add more support for the table.
The work volume or field for this machine is (40cm×40cm×40cm).
Regarding the Dynamic Analysis, the inertia forces and torques were studied, and so the maximum and minimum velocity required to move the actuator head. Consequently, stepper motors were chosen, the number of them is like the number of the axes, these motors rotate (0.9 degree) by each pulse they get, these motors characterized with a high accuracy, the value of rotation will surely taken in consideration to determine the printer accuracy, the load torque for each motor is (4.4 Kg.cm). The building speed according to the (Y) axis is (150 mm/s) in maximum.

This will have to be something of an interim review as I shall be saving this tap, or faucet as the Americans say, to be incorporated in my new kitchen when it is finally installed later this year. Having the tap to look at and admire now will be an incentive to me to get the new kitchen put in. My review today will be solely on the build quality, appearance and presentation of this product. I will update it to include installation and functionality in due course. I felt I just had to get my first impressions down!

All you need is supplied in the box. For what is essentially a kitchen fitting which few people other than plumbers will see before installation plenty of care has gone into the presentation of this unit. The stainless steel body is carefully wrapped in protective tissue and all the parts are presented in a custom fitted box. The kit includes the tap unit itself, hot and cold water Uk Standard flexi-tail hoses, additional sink fittings, ceramic cartridge, User Guide. Everything seems to be of the highest quality and even the flexi tails are made of metal rather than rubber. The mixer tap looks fantastic with a chrome finish with a black silicone grip and feels suitably weighty due to the brass construction. The single lever operates smoothly and feel like it might be damped to achieve this. It has a Ceramic Disc Valve Cartridge which replaces the old fashioned rubber valves and should mean it works drip free. The User Guide takes the form of an exploded diagram and is simple and easy to follow. I include a scan of it in my unboxing video. There is no step by step install guide included as a certain level of knowledge is assumed, otherwise just leave it to the plumber to sort out, as I intend to.

The tap is heavy and feels very robust although I will always be worried about scratching the chrome or bodywork since it is all so pristine at the moment. It really is not too much to say that this device is a thing of beauty even before it is finally fitted. The silicone sleeve looks great now but I hope it will not mark or deteriorate with time and use

I really don’t think you will be able to find a more attractive or better built piece of kit and if as much care and though has been devoted to the functionality as clearly has been to the design then it will be a winner indeed. If I saw this unit in a high end bathroom showroom I would expect it to be in at least the £150 range. The Amazon price of £76.99 whilst not being the cheapest I have seen is still excellent buy..

On the basis of looks and build quality – which is all I can currently comment on – this is a definite BUY.
