We have a tendency to want to jump ahead to more complicated prints faster printing bigger prints etc There are many aspects to successful 3D printing everything from the printer which in itself has a mechanical system electronics system hot end extruder heated bed firmware to the Slicer and all of the parameters available to control the slicing to the filament itself to the actual item being printed With so many variables 100s maybe 1000s of them it is really important to pin down as many of them as you can One very easy place to do this is with the model itself Develop your experience printing the Same model over and over until you nail it Even with a simple model you can and should approach printing it with a methodical approach from the ground up That s the next strategy 3 Practice in Measures I play guitar and was basically self taught When I found new music to learn I did what many untrained folks do and practiced the part over and over again from beginning to end If I made a mistake I started over Then I took lessons from a trained musician My very first lesson was worth every penny My instructor watched me learn a piece and then said Practice in Measures What he meant by this was to learn the first measure music is divided into small blocks of notes called measures which are small and relatively simple Practice it until it is perfect Then practice the second measure until it s perfect Next comb

8. The Top and Bottom solid layer parameters dictate how thick the top and bottom surfaces of your object are when printed These two parameters fulfill essentially the same function as the Perimeters parameter but for the top and bottom of the part You can calculate your top amp bottom thickness by multiplying the solid layer count by the layer height For example 5 top layers will result in a final top thickness of 1mm if your layer height is 0 2mm You also have the option of specifying the top and bottom thickness in millimeters instead of layers 8 Advanced MatterControl Settings General 75 Rostock MAX v2 User s Guide The next page in Print is called Infill and covers how the interior of your part is filled While I covered Fill Density and Infill Type earlier the Advanced mode adds two new parameters Starting Angle degrees Starting Angle The Starting Angle parameter allows you to control the orientation of the infill For example an infill type of GRID with a starting angle of zero degrees is going to look like this Now if you change the starting angle to 45 degrees you ll end up with an infill pattern that looks like the example below Grid 45 degrees Grid infill Note that changing the starting angle will also change the angle in which the top and bottom layers are printed You can see this in the image below this shows the second layer as it would be printed Top amp bottom layer

13. now focused where you need it Here is an example of some of my fan research The part on the left failed in a previous run as you can see due to warping caused by an uneducated 25mm inducted fan blowing at 50 The part being printed on the right was my first attempt at using flexible soda straws 2 of them to direct the air flow to exactly where I needed it I also ran the fan at 20 12 A Strategy for Successful and great Prints 107 Rostock MAX v2 User s Guide Fishing Reel parts The angle of the photo doesn t show it clearly but the double barrels are focused at the tip of the nozzle The dead air space between the tubes prevents air from flowing over the nozzle I know it s terribly clever It s a work in progress and I ve almost got it perfected with a printed double barrel nozzle I suggest doing your own experiments and observations but start conservatively I don t use a fan during the entire part If you find you need to turn the fan on at full blast from no air flow do it in Stages so the hot end can equilibrate properly You can do this manually some slicers can support it or it is easy enough to learn the simple fan mcodes to manually insert them where you need them in the gcode file this is what I do for tricky parts M107 is fan off M106 S50 turns the fan on at 50 the S parameter is the speed from 0 to 100 Using a focused air flow lower air flow and the step up technique I just described you won t
