Flaming Skull

prusaprinters

<p>Files processed through Microsoft 3D Tools upload to reduce file size and ensure no mesh errors.</p><p>Jaw separated from skull, and skull separated from flames to minimize supports, marring, ease of printing and allow multicolor (I'm too lazy yet to learn the painting).</p><p>Flame base 189mm high, 152w x 141d.</p><p>Flames: setting support overhang for 55 degrees or more results in only 1 area needing support above the bottom. PLEASE DON'T try below 55 degrees with support everywhere! It would get pretty ugly. Highly recommend Cura tree support to preserve upper surface below that spot. 3 walls, higher end of filament temp range, and perhaps increase flow rate to 105% to strengthen layer adhesion for the narrower tall flame towers. I used 60mm/s for speedy larger base portion, and added post script g-code &nbsp;to slow to 45mm/s and increase temp at layer 460 (kind of arbitrary) as everything higher is smaller and fragile (sensitive to speed). Recommend Cura Lightning infill with 50% wall overlap. It shaved hours off print and still provided perfect upper surface support. Below .2mm layer height should be unnecessary given the mostly vertical nature of the thing.</p><p>Jaw: prints easily with basic support and settings. I used raft for better bed adhesion, given the small bottom surface size, and slower speed given the small and detailed nature.</p><p>Skull: Teeth print MUCH better if skull is tilted up a bit (as it will open in your slicer). The support under those little guys is necessary or they may string. Took me 2 tries to work that out. I printed with support blockers on right eye socket overhangs and it came out perfect. Remove support from rear to front. This should minimize risk of breaking teeth off while hacking away at support elsewhere.</p><p>Pegs: Separate file to reduce chance of stringing from other print items. Chamfered to ease insertion, and about .2mm tolerance with cavities. Print horizontally, no support, 3 walls and 45mm/s (given small size) for strength.</p><p>Flame filament in picture is AMOLEN PLA Silk Shiny Red Gold Filament. A bit pricey from Amazon at $37, but couldn't find comparable ideal colors for this purpose.</p>
