So heres what I have learned in the last weeks. The three weeks since the Makerbot arrived in my high school tech classroom.
students will cut class to watch the makerbot print
students previously not interested in computer graphics will learn on their own time just to create a design to print
some folks view it as magic
some view it as a toy maker…or just a toy
3d printing makes the object worth little and transfers the value to the design. My four year old already gets this.
And now on to the practical and technical:
there is a lot to learn and you must be ready to tinker and fiddle.
don’t buy one if you aren’t a patient soul. The tech isn’t there. Yet.
set the hbp to 109 degrees for larger objects.
rafts work but aren’t always needed for smaller objects.
as stated my many makerbot vets: a feedrate of around 30 is a sweet spot between speed and resolution
