Acrylonitrile Butadiene Styrene, 3D 프린터의 재료로 사용하는 열가소성(thermoplastic)수지.

ABS는 ABS로 만든 필라멘트를 언급하는 줄임말로도 쓰인다 : 당신의 Mendel에서 ABS를 사용합니까?

네, 그렇습니다.

Mendel_X-축 이송부(Carriage)

[[Mendel]의 X축 중간에서 압출기(extruder)를 고정하고 움직이는 조립체. 흔히 x-carriage라고 한다.


촉매는 자기 스스로 소모되지 않으면서 화학 반응의 속도를 촉진시키는 물질이다. 화학반응이 일어날 때 반응률을 변화(흔히 증가시키는 쪽으로)시키는 물질이다.


공중합체는 주 고분자의 특성을 향상시키기 위한 목적으로 고분자들을 섞은 것이다.

All polymers have principal properties that are desired, but bring others that are not. A good example is Styrene, which is clear, has great accuracy when molded into a shape but is very brittle and ages bad under sunlight. In certain commercial varnishes Butadyene can be added to give it some flexibility and UV protectors to make it more durable. The difference between copolymers and fillers is that the first ones participate in the chemical chain reaction and are bonded to the main monomer.


참조: Hardening.


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.


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.


Fillers are solid materials that are added to polymers (or cements) and that do not interact chemically with it. They remain inert but do add special desired mechanical features to the compound. These can range from density alteration (make the compound heavier or lighter) additional strength (fibers...), resistance to abrasion and improved thermal properties (sands...) or simply thinning the compound to reduce material cost (talc).


A group of parts which handles feeding and extruding of the build material. Consists of two assemblies: a cold end to pull and feed the thermoplastic from the spool, and a hot end that melts and extrudes the thermoplastic.


Fused Deposition Modeling; same as 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).


다음 두 가지로 사용된다:

  • 3D 프린터의 원재료로 사용하는 끈 형태의(주로 3mm나 1.75mm) 플라스틱 재료
  • 압출되는 플라스틱(주로 1mm 미만)


찌그러진 개구리로도 알려져 있으며 인쇄판이 연결되는 부품을 가리킨다. 개구리는 Y축 리니어 베어링에 직접 연결된다. 이 명칭은 오리지널 Sells Mendel 부품이 "찌그러진 개구리"처럼 생긴데서 유래되었다.


PC에서 컴퓨터 수치제어(CNC) 장비-- 대부분의 RepRap들을 포함하는 --로 유선을 통해 보내지는 정보는 G-코드이다. 원칙적으로는 사람이 직접 RepRap에 G-코드를 입력할 수 있지만 대부분의 사용자들은 STL 파일을 읽어 G코드로 변환한 후 장비에 유선으로 전송하는 다양한 CAM 툴체인(CAM Toolchains 중 하나를 이용하는 것을 선호한다. 몇몇 연구자들은 alternatives to G-code에 대해 개발중이다.


The process by which the model hardens to its final form.

가열판(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.

핫엔드(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.

캡톤 테이프(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.


A molecule that, under the correct conditions, can link together with others to form larger molecules called polymers. A monomer must be capable of forming two or more bonds to other monomers.


Usually meant to refer to a specific size of stepper motor.


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.


Oligomers are big molecules composed of monomer bricks, joined together in more or less branched fashion, so as to provide polymerization seeds for the final polymer. A free analogy would be that monomers are to oligomers what a water molecule is to a snowflake. In commercial resins, oligomers are mixed with their monomer components so as to achieve a polymer of desired properties, due to their ability to spatially organize the polymerization process.


(Adjective) Adjustable in all dimensions. A parametric model is one that can be resized and or distorted to suit the user's needs. In CAD software, If a widget has a 1 cm hole in it, you can select that hole and make it a 5 mm hole with a few clicks, as opposed to a triangular mesh (see #STL), which is more difficult to adjust.

The native format of several useful software packages can store parametric models.


Polyether Ether Ketone. A high temperature thermoplastic used as a thermal barrier in the extruder.


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.


Polyvinyl Alcohol, A watersoluble filament used as 3D printing material. Often PVA is used as support material.


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


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.


RepRap Arduino Mega Pololu Shield - one of the more popular flavors of the "Official" electronics.


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.

To reprap
v. To make something in a RepRap machine.
adj. Capable of being made in a RepRap machine.

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. These are becoming less common as Mendel printed plastic parts become more available, but are still very popular. They're often sold in kit form or custom-made from scrounged parts.

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

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.


Stereo Lithographic의 약자로 3D 오브젝트를 기술하는 recommended file format. 디자인 프로그램(예를 들면 AoI)은 3D 프린터나 3D 랜더링 그래픽 패키지에 사용할 수 있는 STL 파일을 생성할 수 있다. STL 파일을 대체할 수 있는지에 대한 논의가 a community specification for an improvement to STL files에서 이루어지고 있다..

찌그러진 개구리

Thick Sheet

A firm flat sheet of material 4-6 mm thick used as a printing surface. A variety of materials have been used, but the most important property is that it must be flat.


Viscosity is a property of fluids determining it's resistance to flow. The higher the viscosity, the more difficult a material will be to extrude or dispense (more energy/pressure will be needed). Also, the higher the viscosity, the less the deposited thread of material will sag or change shape until hardening.

For a detailed definition see Viscosity on Wikipedia.
