A skirt is nothing more than a brim that doesn`t touch the edges of the object that you`re printing. Skirts serve a useful purpose because they help prime the extruder and establish a smooth flow of filament. Most 3D print slicing software will automatically add a skirt to the beginning of each print.
Skirt obviously provides no effect on adhesion except as a visual indicator of whether your filament is sticking and is primarily used as a tell if all the other variables are properly functioning including material flow, calibration of your printer, and whether everything is properly leveled.
A skirt is a line printed around the object on the first layer, but not connected to the object. This helps prime the extrusion nozzle and can be an additional check for bed leveling before the print begins.
Stringing (otherwise known as oozing, whiskers, or “hairy” prints) occurs when small strings of plastic are left behind on a 3D printed model. This is typically due to plastic oozing out of the nozzle while the extruder is moving to a new location.
The skirt is a printed outline of all of the models on the print bed. It`s printed before any of the models and its purpose is mainly to stabilize the flow of the filament through the nozzle. The skirt is also useful to verify the adhesion of the first layer to the print bed.
Side Skirts Offer Aerodynamic Properties

For the best performance, you want the air moving front to back over the car undisturbed. With side skirts, you prevent the air from rushing underneath your vehicle which affects your aerodynamics. The closer your side skirts are to the ground, the more effective they are.

Skirts serve a useful purpose because they help prime your extruder and establish a smooth flow of filament. Observing the skirt also allows you to detect and adjust any leveling or adhesion issues before the actual model begins printing.
The difference between them, however, is that rafts go underneath the printed object, whereas brims go around the printed object. A brim can best be described as a flat and horizontal expansion of the printed object`s initial layer.
Warping occurs due to material shrinkage while 3D printing, which causes the corners of the print to lift and detach from the build plate. When plastics are printed, they firstly expand slightly but contract as they cool down. If material contracts too much, this causes the print to bend up from the build plate.
Adjust Print Temperature and Speed

Therefore, lowering the print temperature and print speed can help to reduce the risk of blobs and zits. The temperature of your nozzle will depend on the type of filament you are 3D printing. For example, PLA filament typically requires a nozzle temperature of between 200-210 °C.

Skirts or dresses made of I ightweight fabric or lace need a lining to add extra body and shape. Soft fabrics which drape easily may need a lining to prevent their graceful lines from becoming flattened. There are persons whose skin is sensitive to certain fibers.
What Is It? Brims are very similar to skirts in that they`re multi-line structures that are always only one layer in height and form a perimeter around the first layer of a printed model. However, unlike skirts, a brim is always directly connected to the first layer.
A skirt is basically a detached outline of your model (Source: Tobias Hullette via All3DP) When you enable skirts in Cura, your printer will initiate your prints with a line around the main part. This initial line has a few benefits.
Increase Infill Density

It causes the upper layers to sag, resulting in wide, visible air gaps between the infill and the top layers. If you`re noticing gaps in your top layers, try increasing the infill density to 30-40%. This range should support the top layers and noticeably reduce any gaps in your 3D prints.

Side spoilers work in a very similar way, helping the vehicle maintain traction at high speeds. Fast driving results in air pressure that naturally wants to lift the car from the ground. Side skirts and side spoilers are designed to help the car grip better, which means better control and a safer driving experience.
By attaching the side skirts, the pressure exerted on the front side of the rear wheels is reduced, because the streamwise flow momentum is weakened in the region between the front and rear wheels.
A 3D FDM/FFF printer is capable of creating parts from a variety of materials, including plastics, silicone, metal, and even food paste. Filaments are often used by users, with a wide range of choices available.
3D printing materials can vary widely, with options that include plastic, powders, resins, metal and carbon fiber. These materials make 3D printing a promising option for many parts, from highly accurate aerospace and industrial machinery components to customized consumer goods.
Not all overhangs need to be supported. The general rule of thumb is: if an overhang tilts at an angle less than 45 degrees from the vertical, then you may be able to print that overhang without using supports.
The ideal range for PLA filaments is between 185-210 degrees Fahrenheit. If the bed is too cold, the PLA will not stick. You can also use a heated build platform to promote better adhesion. In addition to checking the temperature of your 3D printer and the bed, it`s important to adjust the printing speed.
Most of the reasons why the raft/bottom is not sticking to build plate are related to the build plate and the first layer. If the build plate is not flat, you will likely have adhesion problems and possible failures especially when you are attempting large prints.
than printing a fully solid part. but different infill geometries can be used for different needs. Triangular Infill: Triangular infill is the strongest infill pattern because triangles are the strongest shape.
There are a few settings that you can tweak, but the most common cause of a weak infill is under-extrusion. Under-extrusion can be caused by several factors – a printing speed that is too high, a printing temperature that is too low, skipping in the extruder gear, or a clogged nozzle.

Broken plastic ribbon that goes to the ink cartridges
ANSWER : In my experience, they tear at the ends where they hook on metal posts. What I do is wrap some Scotch tape around the torn end and then cut out the slit with a razor. Then you have to thread it through the U shaped sensor at the back of the cartridge holder. The sensor is an optical one that counts the lines on the encoder strip. That tells the printer the location of the assy. Then you have to hook it on each end. If you have small hands, you can do it without disassembling the printer. It’s a lot easier with the printer disassembled. My hands are on the big side, but I know how to do it. There is a fair amount of cussing before I get it done.

narrow plastic film with spring is out, need to put it back
ANSWER : That is the encoder strip. It goes through a U-shaped photo sensor at the back of the cartridge assembly. It might be hard to see with the cover on. It has to slide in between the 2 posts. Then you stretch it tight and where the 2 ends point, there should be a metal hook that you attach it to.
