Moreover, PEEK plastic is also very easy to machine and shows good dimensional stability. Due to its mechanical strength and lightweight, PEEK could be used in many applications to replace metal. PEEK plastic physical and strength propertiesĪs we can see from the data, PEEK shows great mechanical strength and it is a plastic that combines rigidity and toughness. PEEK is a plastic that combines all those characters. The material requirements of the industry are high-temperature resistance, very good mechanical strength, and excellent insulation performance. We can see many PEEK plastics are used in the oil logging technology as the insulation components. PEEK is also the most widely used high thermal stable plastic. One of the most important characters of PEEK plastic is its exceptional high continuous working temperature. The glass transition temperature is 150℃.This support material is fed through another nozzle.Īfterward, when the model is put into a bath with special soap, the support material dissolves.PEEK is a high-performance, semi-crystalline plastic which shows many unique properties.
Since the material of the model cannot be deposited in the air, the support material prevents it from falling down. When your model contains overhanging sections, the printer needs to build supporting material. When a layer is drawn, the platform lowers by one layer thickness so the printer can start with the next layer. The nozzle moves to drop the material at the correct location, drawing your model line by line. It is fed from a spool to the nozzle where the material is liquefied and ‘drawn’ on the platform where it immediately hardens again. In an FDM printer, a long plastic wire is used in place of glue. The glue is heated up until it melts and is then pushed through a fine nozzle in the front of the glue gun. You can compare it with a hot glue gun into which you put sticks of glue. Supports are not inherently detrimental for your design, but they do add complexity to the printing process and lead to less smooth finish on overhanging parts.įDM PEEK is 3D printed using FDM (Fused Deposition Modeling) technology.įused Deposition Modeling is used to build your design with this material.
Sometimes the interlocking/moving parts can’t be printed, since the supports inside the cross section can’t be removed.īecause each layer needs to build off the last, for some material, angles of more than 45 degrees generally require supports to be printed along with the design. If escape holes are not large enough, or the geometry of the product makes it difficult to shake or blast the powder out, we cannot successfully clean it. When products contain hollow cavities, they are often filled with powder/liquid even after they are removed from the build tray. Normally you don’t need to consider this, our technician will add escape holes before printing. You can also try a material with a smaller minimum clearance.Įscape holes allow unbuilt material inside hollow products to be removed. If your clearance is too small, try making the gap bigger, or consider fusing the parts or features if their independence is unnecessary. To ensure a successful product, make the clearance between parts, walls, and wires greater than the indicated minimum. Engraved or debossed details go into a surface.Ĭlearance is the space between any two parts, walls or wires. If your product has details smaller than the minimum, try making them larger, removing them, or considering a material with finer detail.Ī detail is a feature whose length is less than twice its width. We may refrain from printing products with details smaller than the minimum, since the final product will not be true to your design.
To ensure details come out clearly, make them larger than the indicated minimum. Details that are too small can also be smoothed over in the polishing process. The minimum detail is determined by the printer’s resolution.When detail dimensions are below the minimum, the printer may not be able to accurately replicate them. Through holes must also allow for line-of-sight clearance to ensure all material is cleared during post-processing.Ī detail is a feature whose length is less than twice its width. The thicker the wall section, the less accurate the hole becomes. The accuracy of a hole not only depends on the diameter of the hole, but also on the thickness of the wall through which the hole is printed. An unsupported wire is connected to walls on less than two sides. A supported wire is connected to walls on both sides.Ī wire is a feature whose length is greater than five times its width. A supported wall is one connected to other walls on two or more sides.Īn unsupported wall is one connected to other walls on less than two sides.Ī wire is a feature whose length is greater than five times its width.
