<p>I'm looking to buy my first 3D Printer, on a tight budget of $250. Unfortunately, this printer that I found on Amazon comes with all the bells and whistles, <em>except</em> for a heated bed. </p>

<p>I want to know if this would affect printing severely, as I have read that the plastic/ filament cools down rather quickly, and that it results in Printer "fails". </p>

<p>I'm actually a bit nervous with this buy, as I don't want to spend $250 on a printer that produces 90% print fails.</p>

<p>An example of the printer I'm referring to is the <a href="http://rads.stackoverflow.com/amzn/click/B015FXQZ6O" rel="noreferrer">Cube 3 Printer, Grey
by 3D Systems</a>.</p>

The only time that I've observed clicking from the extruder on my Anet-A8 is on the first layers when I have the head height set too low - the nozzle is unable to extrude at a high enough rate to allow the filament to progress as requested.
If you have a somewhat repeatable scenario, you could try reducing the filament feed rate to 90% or so, and see what effect that has. I have already observed with one of my reels of filament that 90% feed rate gives me a less over-filled solid area, so maybe the default feed rates are a little on the high side (or this filament is of excessive diameter).
