Wooden Filament Coaster Set

thingiverse

Here is a set of 4 coasters designs, an 8-piece and a 4-piece tray. There is also a blank coaster into which you can insert your own DXF and extrude to 1.6mm from the inside bottom surface. Send me a message for a link. This was designed to print with a 0.8mm nozzle and woodfill pla with no more than 40 percent wood shavings. Printing Settings: Wood PLA expands a bit on heating. It is also slightly abrasive. You can finetune coasting and priming settings to reduce blobbing and stringing etc. Its prone to stick to the nozzle exterior when a new extrusion starts, which is why I suggest making use of a copper plated nozzle. Tune your retraction settings with a stringing test. https://www.thingiverse.com/thing:2219103 For this print: - Initial layer height is 0.3mm – 0.4mm - Layer height is 0.2mm - Line width 0.8mm - Wall thickness 2.4mm - Enable ‘Filter out tiny gaps” setting. - Make your print surface hot, about 60 degrees. - Do not print the outer walls first. - Play around with your speed settings. Some people say print slower to create better adhesion. In this model I print between 35mm/s for initial and top layers to 40mm/s for infills and walls, and you can probably go faster after your initial layers. - Wall line count is 4. - Bottom layer count is 2. - Top Layer count is 3 - Infill Pattern is Zig Zag - Infill line distance is 1.6mm. You can reduce this, but this keeps the coaster nice and firm. Its only two layers. - Top and bottom layer pattern is Zig Zag. Concentric might give you a smoother finish and reduced print times, but the concentric pattern increases the risk of filament adhesion to your nozzle. - Enable ironing with 10% flow, Speed at 30mm/s, 0.4mm inset, Zig Zag. Here you can try concentric, but I find Zig Zag always give the best result. - Initial Layer Flow 115% - Print temperature at 205, but you can increase this to about 210 for the initial layer. You can also extrude at different temperatures at different levels for a color variation. - Acceleration is 900mm/s’ and Jerk is 10mm/s. - Enable retractions, and here you must adjust it according to the extruder you have. I am using a direct extruder, so I only retract about 3mm, at 35mm/s. - Enable Combing mode for all. - Enable Z hop when retracted. - Print with a brim, at least 4 lines wide. - I suggest drying your filament at 60 degrees for a few hours before starting. - Works best with a rough steel print surface. - Set your print up to print items one at a time. 4 coasters will take you 6 hours with these settings, but you can print up to 9 at a time on a 300 x 300. The 4-piece coaster tray will take 2 hours and 20 mins, and the 8-piece will take 3 hours and 15 minutes. Turn ironing off for a dramatic decrease in print time.
