![]() Apart from the obvious one such as a 3D model as well as a 3D printer, you will need lots of other items as well. There is a wide range of free 3D slicer software available, some of them are free and opensource.The 3D printing process requires a whole range of highly innovative tools to get the job done properly. These can print materials with different colors and different properties. Nowadays, many printers come with multiple extruders. If you have multiple extruders on the machine, 3D slicer program helps to assign different roles to each extruder. Different polymers have different requirements of nozzle and print bed tempertaures. Lastly, printer temperature also depends on material type. Also, high temperatures can lead to “over extrusion” and result in blobs or zits. if the print speed is not matched to the temperature, it can lead to “under extrusion” due to improper melting of filaments. If printer speed is set to higher then printer temperature should be increased. Printer temperature is related to printer speed. Grid Raster Contour Zigzag Spiral Temperature in slicer software Every slicing program for 3d printing has built in printer paths. This will result in a shorter fabrication time. A path planning strategy can help optimize the overall printing process. Therefore it is the printing path is crucial in 3D printing. ![]() Printing paths have direct impact on printing time, surface roughness and strength of the model. Every slicer software has print speed parameters which should be considered based on 3D object. The speed can also vary depending on the material used for printing. These settings can be changed based on the geometry of the object. The 3D Slicer software has default speed setting. Higher shell count results in higher strength. The strength of the object is dependent on the number of shells present. Outer Shell Thickness is the outer layer thickness of the 3D object. High Resolution Low Resolution Medium resolution Object Shell Thickness It takes more time to print with high resolution and smooth surface objects. Smaller layer height gives high resolution and smooth surfaces. Layer Height or Resolutionĭifferent layer height generates different resolution. 3d printer volume and part size are main points which decides orientation. ![]() We need to align the 3d printing model in the given space. The Brim layer is the first print layer which touches the base of the object, lastly raft is the base layer under the bottom of the object. Skirt is a single outline layer printed around the base of the object and not touching its base. The slicer provides base layers like rafts, skirts and brims to avoid these problems. This is because of the printer bed properties. Base Layers (Rafts, Skirts and Brims)ģd printed objects get stuck to the printer bed and also generate variations in printed object. These are examples of where models need support. Overhangs less than 45 degrees in angle and bridges more than 20mm long needs supports. This supporting layer is called the support structure. If a model has an overhanging part, it still needs a supporting layer. This means every layer needs an underlying layer to support it. Printer prints, one layer on another existing layer. The design of the infill pattern can have an impact on the strength and flexibility of the 3D prints Concentric Grid Honeycomb Triangular Hexagonal Support Structure The 3D Printing Slicing software helps to set infill density as well as type of infill pattern. Infill density is the amount of internal structure in a object. ![]() The slicer converts this solid object into hollow and adds internal structure of walls to provide strength. 3d Slicer Program Features of Slicer SoftwareģD objects or models are solid and it takes large amount of material and print time. The slicer first converts object into stack of layers followed by other specifications like infills, supports, base layers, print speed and temperature are converted to G-code. The 3D printer slicer or slicing software converts 3D model in STL format into G code format. It converts the STL file into layered structure. 3D printers need to convert the 3D models into printable file format.
