What is RepRap in 3D printing?
RepRap machines are self-replicating machines that can 3D print parts of themselves to use to create additional machines. This original machine has led to a variety of improvements, the best known probably the Prusa i3.
How small can a 3D printer print in microns?
This means that the printer can reliably produce XY features as small as 150 microns, about the size of a human hair. The Form 2’s minimum feature size on the XY plane is about 150 microns—only 10 microns larger than its 140-micron laser.
What is the strongest 3D printable material?
Polycarbonate
Polycarbonate is the undisputed king of materials for desktop 3D printing. Even we were surprised at polycarbonate’s strength. In comparison to nylon at 7,000 psi, polycarbonate’s tensile strength of 9,800 psi makes it the ideal choice for high-strength, functional components.
What is the best nozzle size for 3D printing?
We recommend that the best printing nozzle diameter is 0.5mm for composite materials, and for any metal, glass of Carbon Fiber materials you’ll need a hardened nozzle. The brass one that came with your printer likely won’t last, and will bore out to a larger size after a few hours of printing.
Is RepRap dead?
Many of the folk who once contributed to RepRap have not posted in years, or have gone on to other things. The current field of 3D printing is alive and well. There is much owed to the first generation of RepRap folk.
Is Creality a RepRap?
Creality are known for releasing some of the most highly rated and reliable low cost RepRap 3D printer kits in recent years, with multiple iterations of the popular CR-10 available.
Which is stronger PLA or PETG?
Unlike PLA, PETG is water-, chemically- and fatigue-resistant. For example, PETG is stronger than PLA (though weaker than ABS) and more flexible than ABS (though less flexible than PLA). This, understandably, makes it a popular material as the short-comings of both materials are lessened within PETG.
What is a good wall thickness for 3D printing?
If you want higher-strength parts, use larger values such as a wall thickness of 2-3 mm and a top and bottom thickness of 1.6-2 mm. For more display-oriented models that don’t need much strength, you can get away with a 0.4-mm wall thickness and a top and bottom thickness of 0.2-0.8 mm.
Do all 3D printers use the same nozzle?
The absolute standard in 3D printers today is the 0.4-mm nozzle, which is found in almost all popular machines. For example, a 0.4-mm nozzle has a recommended maximum layer height of 0.32 mm. It goes without saying that larger nozzles will extrude more material through thicker layer heights and widths.
