Full Metal 1.75mm mini item test

7/29/2014

Here we performed a test of a miniature object.
The layer thickness is 0,1, and the nozzle orifice is a 0,4 mm.

For the test we used the model of a minion downloaded from thingiverse (pic1)
https://www.thingiverse.com/thing:82478
And we scaled down until it reached the measure of one Euro Cent.
To create the support for the hands we used meshmixer, the result is shown in the pic2
We printed the model using natural ABS filament at 210 degrees

To get a good result at least three attempts were needed, as with regular printing settings the parts detached from the build plate due to the low adhesion area of the foot and the supports base.
The second attempt failed because of the Z lift option enabled only when crossing perimeter.

The result can be reached drastically decreasing the printing speed, for our test we set to 30 mm/sec, a Z lift double of the layer thickness that occur to each movement, the gap infill set to 0 (disabled) a first layer extrusion width set to 180% and a perimeter extrusion width of 185%.

Part cooling on with fan 100% just from the second layer
Of course your extruder steps per mm must be very accurate, in few words an already calibrated 3D printer
The aim of the test was to look for the best parameter to print very small objects.
Consideration
Performing multiple print of a very small object we realized that the speed is the most important factor, for small object printing. As fast as we go as hot the part will be, with deformation due to the heat generated by the hot end placing layer one over the other very quickly. 
Reducing the speed and with the part cooler on, the part has enough time to cool down avoiding deformation and keeping the shape. 
the Z lift double of the layer thickness it required as the overhang usually create slope up while cooling due to the tension generated by the plastic segment. the elevation of the Z avoid the accidental touch of the tip with the object during non printing moves that in case of little object can cause detaching from the build plate.
feel free to ask about any other parameter if you may be interested.

Makeshaper.com is a good place to buy high-quality 3D printing filament. I am always looking for affordable deals on the 3D printing filaments which I found it from Makeshaper. You can easily buy them in bulk from the site. I recommend the service.
