![]() Doing so will reduce the amount of painting that needs to be done once printing is over and you’re finishing the object.Īdmittedly colour is less important for those truly professional-grade finishes though, because of the amount of primer paint coats needed. Specifically, variations in the diameter of the filament can lead to under-extrusion and over-extrusion problems during printing, both of which will produce a final object with serious surface flaws that will have to be dealt with through finishing.įinally, consider using a color of filament that will closely match the desired color of the finished object. In addition, cheaper filament is not produced to the rigid tolerances necessary for high-quality end results. Poor quality filament contains impurities that will negatively affect how the material melts, extrudes and cools. The quality of the printing filament that you are using can impact end quality as well. ![]() Slicer settings are not the only thing that affects the amount of potential finishing work that may need to be done once an object is printed. Doing so will insure that your object won’t be damaged or deform during the finishing process.įor more information on slicer settings, take a look at our article on the subject here. ![]() Again, because sanding removes material from the surface of an object and requires the application of a certain amount of pressure to do so, you’re going to want to increase your fill density when printing the object. However, an object with more infill will be stronger and heavier than an object with less infill. Likewise, if 0% is selected, the printed object will be empty inside.įill density is used to conserve filament while printing and speed up printing times. This means that if 100% fill density is selected, the printed object will be solid, with no empty space inside the outer shell. Fill density is usually measured as a percentage of whole, as opposed to a unit of measure. Fill Densityįill density or infill is a measure of how much material will be printed inside the outer shell of the object in question. So, when you’re planning to finish your object post-printing through sanding, you want to increase the shell thickness to account for the material that you will be removing later. Obviously, thicker walls make for a sturdier object. The higher the setting is for shell thickness, the thicker the outer walls of your object will be. Shell thickness refers to the number of layers that the outer wall will have before infill printing will begin. This means that your object is going to need to be a bit more robust in terms of thickness and infill than you previously planned for.Ī shell is the outer wall of a designed object. You’re going to be sanding 3D prints after printing in order to obtain the smoothest surface possible. Because of this, it pays to experiment with your print speed to see what works best for the job you’re printing. ![]() On the other hand, more complex objects with more detail will benefit from a slower print speed. In general, simple objects with less detail can be printed faster without much loss of quality. Therefore, optimal speed depends on the object you are printing and the filament material that you are using to fabricate the object. Print speed is how fast the print head travels while extruding filament. Print speed is another important setting that can contribute to overall object quality. Read on to learn more about painting PLA and other 3D materials. You’ll spend more time printing, but less time sanding 3D printed parts before painting them. If you’re intending on painting 3D printed parts after you’ve finished printing, it may be best to use a lower layer height. When you choose a thinner layer height, a higher level of detail is possible and your layers will tend to blend into one another. When you choose a thicker layer height, your object will have less fine detail and the layers will be more viable. In some sense, layer height in 3D printing is akin to resolution in photography or videography. Layer height is the setting that establishes the height of each layer of filament in your print. Your slicer settings have a lot to do with how your finished object looks – particularly layer height. On the subject of printing practices, one of the best ways to minimize the amount of finishing work cleaning up 3D prints is by starting at the very beginning of the printing process.
