Nozzle size: Nozzle diameter. thinkFAB’s default nozzle diameter is 0.4mm. If you choose 0.3mm, 0.5mm or 0.8mm diameter nozzle,
please fill the corresponding right feature.
Nozzle size has a little influence on the accuracy in Z axis direction. But if printing fine structure model, smaller diameter can help get better result. The relationship of size of the nozzle and print speed are 1:1^2. So increasing the nozzle will greatly
improve print speed.
Filament Diameter: Printer filament diameter. Please put the exact number. Too big or too small will influence the extrusion.
Filament Diameter 2: The 2nd extruder filament diameter. If the same as the main extruder, please set as 0.
Minimum travel: Minimum amount of travel needed for a retraction to happen at all. To make sure you do not get a lot of retraction in a small area. Recommended 2 for best performance. Too small a number will lead to frequent retraction.
Enable Combing: Combing is the act of avoiding holes in the print from the head to travel over. If you enable combing, extruder will always touch the surface of model but disable retraction. If combing is disabled the printer head moves straight from the start point to the end point and it will always retract. Default is enable combing, but it will increase printing time.
Minimal extrusion before retracting: The minimal extrusion that needs to be done before retracting again. If a retraction needs to happen
before this minimal is reached the retraction is ignored. This avoids retraction a lot on the same piece of filament which flattens the
filament and causes grinding issues. Recommended 0.02 at best performance, 0 means unlimited retraction frequency.
Dual extrusion switch amount: Amount of retraction when switching nozzle with dual-extrusion. After switching, filament in the non-working
nozzle needs to be retracted to avoid oozing. Set as 0 for no retraction at all. Recommended setting is 25 for best performance.
Enable cooling fan: Enable cooling fan during printing to cool down the filament.
Minimal layer time: The minimal time of printing layer to ensure enough cooling time before printing next layer. Print speed will adjust automatic to satisfy this feature.
Fan full on a height: The height at which the fan is turned on completely. For the layers below this the fan speed is scaled linear with the fan off at layer 0.
Fan speed min: Minimal fan speed when normal printing
Fan speed max: Maximal fan speed when automatic slowing down printing.
Minimum speed: Minimum printing speed of each layer. Recommended setting as 10 with best performance. Too slow will result in nozzle oozing.
Cool head lift: Lift the head, if the minimal layer time is not enough, to extend the cooling time for model cooling.
Spiralize the outer contour: Spiralize is smoothing out the Z move of the outer edge. This will create a steady Z increase over the whole print. This feature turns a solid object into a single walled print with a solid bottom. When enabling this feature, the top will not be printed and infill is automatically set as 0.
Line count: The skirt is a line drawn around the object at the first layer. This helps to prime your extruder and to see if the object fits on your platform. Recommended setting is 1 for best performance. Setting this to 0 will disable the skirt. Multiple skirt lines can help priming your
extruder better for smaller objects.
Start distance: The distance between skirt line and model. Default distance is 3
Minimal length: The minimal length of the skirt, if this minimal length is not reached it will add more skirt lines to reach this minimal length. Recommended setting is 250 for best performance. If the line count is set to 0 this is ignored. If the model is too small, it will have a too short skirt line and that will not help clean the nozzle.
Solid infill top: Create a solid top surface, if set to false the top is filled with the fill percentage. Disable this feature and set fill density as 0 to print cups/vases that are without top model.
Solid infill bottom: Create a solid bottom surface, if set to false the bottom is filled with the fill percentage. Disable this feature and set fill density as 0 to print buildings that are without bottom model.
Infill overlap: Amount of overlap between the infill and the walls. There is a slight overlap with the walls and the infill so the walls connect firmly to the infill. Recommended setting as 10 with best performance. Too big will influence quality of model surface.
Fill amount: Support print density. Recommended setting as 15 with best performance. More density makes the support difficult to remove. Less density influences print quality.
Distance X/Y: Distance of the support material from the print, in the X/Y directions. 0.7mm gives a nice distance from the print so the support does not stick to the print. Longer distance will influence support performance.
Distance Z: Distance from the top/bottom of the support to the print. A small gap here makes it easier to remove the support but makes the print a bit uglier. 0.15mm gives a good separation of the support material. Longer distance will influence support performance.
Brim line amount: Default is 5, more lines, more firmly the model sticking to platform.
Extra margin: If the raft is enabled, this is the extra raft area around the object which is rafted.
Line spacing: When you are using the raft, this is the distance between the centerlines of the raft line.
