RepRapWiki:Glossary

From RepRapWiki

RepRap用語

ABS

Acrylonitrile butadiene styrene. A thermoplastic used as a 3D printer material.

Often ABS is used as a short form, actually referring to filament made of ABS: do you use ABS in your Mendel?
丙二烯苯乙烯。一種作為三維打印機材料的熱塑性塑膠。
通常ABS是代表ABS熱融絲,實際上指的是RepRap所使用的材料

Bed

The build plate of the 3D printer on which parts are actually made.
RepRap原型製作機的原件建構平台。

Belt

Toothed gear belt. Usually fiber-reinforced to prevent stretching. Used to transfer movement from the motors to other parts of a machine.
齒輪皮帶。通常使用於馬達的傳輸運動。

BOM

Bill of materials. A list of parts. There are BOM for the whole Mendel and for individual components.
物料清單,所有構成RepRap原型製作機的材料清單

Carriage

The moving middle assembly on the x-axis of Mendel which holds the extruder. Often referred to as: x-carriage.
壓出機的X軸的托架。簡稱X軸

EVA

Ethylene vinyl acetate. Several early RepRap research experiments used off-the-shelf EVA glue sticks in hot-glue guns. Those glue sticks are mostly EVA which melts around 85°C.
乙烯醋酸乙烯酯。據若干早期RepRap研究實驗中使用的現成熱融膠。這些熱融膠大多是85℃左右熔化

Extrude

The act of placing the build material on the build platform. Normally by heating thermoplastic to a liquid state and pushing it through a small nozzle.
擠出通常是由加熱系統將 熱塑性塑膠 熔化為液體狀態，並擠壓通過一個眼模注料於加工平台之上。

Extruder

A group of parts which handles feeding and extruding of the build material. Consists of two assemblies: a cold side to pull and feed the thermoplastic from the spool, and a hot side that melts and extrudes the thermoplastic.
經由供料和擠出構建材料。融化並聚合形成的熱塑性塑料。

FDM

Fused deposition method. Same as FFF.
熔融聚合法。請參考 FFF。

FFF

Fused filament fabrication. Where a droplet of one material (plastic, wax, metal, etc.) is deposited on top of or alongside the same material making a joint (by heat or adhesion).
熔融長絲聚合製造。凡熔融態材料（塑料，蠟，金屬等）聚合在旁邊同樣的材料作出聚合物（通常以熱或附著力聚合）。

Filament

Two uses:

• Plastic material made into (often 3mm) string to be used as raw material in 3D printers.
  
• Extruded plastic (often <1 mm)

兩種規格:

• 塑膠材料（通常為 3mm）,通常為3D原型製作機的原料。
  

物理化學

• 擠壓塑料（通常是1mm）

Heated Bed

A build surface that is warmed in order to keep the base of an extruded part from cooling (and shrinking) too quickly. Such shrinking leads to warping internal stresses in RP parts. The most common result is corners of parts lifting off the build surface. Heated beds usually yield higher quality finished builds.
保溫器為了壁免擠出材料冷卻或收縮的速度太快。這種收縮會造成原型元件內部的應力。最常見的結果是角落部分材料剝離構建面。保溫器通常使用在高質量的元件製作。

Hot End

The parts of the extruder that get hot enough to melt plastic, or potentially other materials. Hot end parts use materials that can stand up to ~240 C heat (for current thermoplastic extrusion). The hot end usually refers to the tip of the extruder as it should be hottest there.

Kapton tape

Heat-resistant polyimide adhesive tape, used to secure the heating element to the extruder barrel. It can also be used on the surface of a heated bed.

Nichrome

An alloy of nickel and chromium. Nichrome wire is used as a heating element in many extruder barrels and some heated bed designs. Simpler and less messy enamel resistors are often used for the same purpose.

NEMA

• NEMA14 - A smaller StepperMotor used in Huxley and others.
• NEMA17 - A larger, more powerful StepperMotor used in Mendel, and many others.
• NEMA23 - An even larger, very powerful StepperMotor.

PEEK

Polyether ether ketone. A high temperature thermoplastic used as a thermal barrier in the extruder.

PLA

Polylactic acid. A biodegradable thermoplastic polymer used as a 3D printer material.

Often PLA is used as a short form, actually referring to filament made of PLA: I use PLA in my Mendel.

PTFE

Polytetrafluoroethylene (Teflon). A slippery thermoplastic often used as a barrel in the extruder to minimize friction with the filament.

Raft

A technique used to prevent warping. Parts are built on top of a 'raft' of disposable material instead of directly on the build surface. The raft is larger than the part and so has more adhesion. Rarely used with heated build surfaces.

RAMPS

Reprap Arduino Mega Pololu Shield - one of the more popular flavors of the "Official" Electronics.

RP

Rapid prototyping. Creating an object in a matter of hours on a "3D printer" as opposed to sending out a job to a modelling shop that can take days or weeks.

RepRap

A RepRap machine is a rapid prototyping machine that can manufacture a significant fraction of its own parts.

The RepRap project is a quest to make a desktop-sized RepRap machine.

v.t. (in lower case: to reprap): to make something in a RepRap machine. ( RepRapWiki:About )

reprappable

reprappable - adj. capable of being made in a RepRap machine. ( RepRapWiki:About )

RepStrap

A 3d printing machine which can be used to make a RepRap, but is not a reprap itself, as it wasn't made by something like itself. Becoming less common as Mendel printed plastic parts become more available, but still very popular. Often sold in kit form or custom-made from scrounged parts. See also: What Tooling Do You Have

Stepper Motor

Motors which operate only in discrete increments of rotation. This is the type of motor most commonly used in Mendel, the earlier Darwin, and Repstraps.

STL

Stereo Lithographic

A recommended file format used to describe 3D objects. A design program (e.g. AoI) can produce an STL file which can then be fed to a 3D printer or 3D rendering graphics package. Possible alternatives to STL are discussed at a community specification for an improvement to STL files..

Thick Sheet

A firm flat sheet of material 4mm - 6mm thick used as a printing surface. A variety of materials have been used, but the most important property is that it must be flat.
一個4~6mm厚的印刷平台。材料不拘，但它必須是平的。

Vitamin

A non-replicated part

In RepRap jargon, a "vitamin" is anything that you need to build a RepRap which cannot be printed on a RepRap. For example, bolts.
在RepRap行話中，“維生素”是現在無法以RepRap複製的元件。例如，螺栓。

Wade's Extruder

An alternative to the standard extruder 一種替代標準異型壓出機
