边缘
布林由3D印刷材料组成,周围并附着在物体的底部,以帮助粘附在床/印刷表面上。
EEPROM
EEPROMis like RAM for a 3D printer’s electronics. Some values can be stored here and accessed quickly, in addition to what is known in firmware and held permanently.
G-code
G-code is, in simplest terms, the language used by software to tell machine tools what to make and how to make it. The “how” in this interpretation is defined by instructions on where to move, how fast to move, and through which paths in a plane to move. For FDM/FFF 3D printers, G-code also includes instructions on how quickly or slowly to extrude/retract filament.
There are a few different ways to prepare GCode for a printer. One is to use a slicing program to generate lines of G-code from a 3D model. These programs take a CAD model, slice it into layers, and output the G-Code required for each layer. Slicers are the easiest way to transform a 3D model into a printed part, but the user sacrifices some flexibility when using them.
Another option for G-Code generation is to use a lower level library. Libraries offer precise control over the tool path, and thus are useful for complex prints that do not accept blind slicing in a single run by a pre-determined sequence in a unified program. The final option involves writing custom G-Code. While absolutely unsuitable for an entire model, this may be the best choice for running test lines while calibrating or troubleshooting a printer.For instance: easily-interpretable G-code exists for homing the carriage of a printer on an axis, turning a motor on or off, making a resistor heat up or cool down, setting maximum operational speeds, and a variety of other functions.
电镀
电镀describes the process of readying a model for 3D printing by placing it on an imaginary flat plane as a representation of where the model will be printed on the 3D printer’s build platform. Individuals rarely plate more than a few objects together at the same time, but enterprise-level printers which construct objects in a durable powder medium (automatically supporting all overhanging geometries) can plate dozens or hundreds of objects together in the same print run. This saves time and money, as these machines are expensive to operate and their feedstock is not infinitely reusable.
PID
PID调整是指某些Reprap 3D打印机中使用的比例综合衍生控制算法,以稳定电子元件的热量输出。正确调整固件中的P,I和D值可以帮助标准化热台和加热床的温度。
Raft
A raft consists of a 3D printed material pillow onto which material can be printed, this can help more delicate or complex shapes to adhere to a bed/print surface.

Slicing Error
Slicers are complex tools that rely on correct data. Inserting models or parameters that do not fit the software can easily result in errors, and even a properly sliced object can still print incorrectly if care is not taken to regulate the host software’s interpretation of sliced models and governance of the 3D printer itself.
The most common reason to encounter a slicing error is non-manifold mesh. Since a manifold mesh is watertight (no holes allowed), a non-manifold mesh may undetectable holes between surfaces or vertices. That is: every edge of the describing triangles in an object must have exactly two connected triangles. Additionally, objects stacked together without unification can result in non-manifold errors. For instance, if embossed letters are not fused to a surface, they may hover slightly above it – this will make the model unacceptable for slicing. If it does not return an error, slicing software may drop the offending characters to the bottom of the ‘floor’ of the virtual environment, often fusing them with the object they were meant to adorn. Another typical error involves using very tall layer heights. Layer height must be smaller than nozzle diameter for the model to slice.
Support
This printed material aids in creating complex geometries and overhangs that might otherwise fall if printed over thin air. Using PVA (or HIPS) enables support material to be washed away with water (or limonene for HIPS) after printing. Support can be printed using the same material as the main print, however this creates attachment points that must be sanded smooth. In order for a printer to use support material of a different variety than its model material, the printer must be equipped with two or more extruders. These will operate almost simultaneously to build the final object and the supporting material around/within it.
Warping/Lifting/Curling
As an FDM/FFF 3D printer prints, the material extruded rapidly cools – either in open air or in the presence of fans controlled by software. Depending on the material, if this cooling occurs too quickly or slowly it can cause a print to lift from the printing surface and ruin the overall appearance of a model, as well as interrupting the deposition of additional layers. Warping and curling occurs when the print adheres properly to the printing surface, but thin parts bend as they cool – possibly disrupting further deposition or the overall structural integrity of the model.
