A

ABS = Acrylonitrile Butadiene Styrene 

ABS/PC = ABS and PolyCarbonate Blend

ASA = Acrylonitrile Styrene Acrylate

B

BMI = Building Information Modeling

BPA = Bisphenol-A (PSF)

 monomer used in production of some PolyCarbonates

C

CF = CARBON FIBRE

CNC = Computer Numerical Control

machining process using computer-controlled tools to machine tool the parts.

D

DDM = Direct Digital Manufacturing

 the additive fabrication directly from a CAD file, without tooling, moulding and machining; 3D printing.

DI = De-Ionised (Water)

DPM = Dipropylene Glycol Methyl Ether

E

EPDM = rubber

EPX = EPOXY

in the context of additive, this could refer to two-part EPX81 by Carbon 3D.

F

FPU = Flexible Poly Urethane

G

H

HCR = High Consistency Rubber

 one of the oldest materials producing silicone rubber parts via Injection Moulding

HDPE = High Density Poly Ethylene, RIC level 2 

called alkathene or polythene when used for pipes

HIPS = High Impact PolyStyrene

HSE = Health and Safety Executive

HTV = High Temperature Vulcanisation

high temperature curing rubbers for Injection Moulding

I

IM = Injection Moulding

IPA = Isopropyl Alcohol, Isopropanol; ALCOHOL C₃H₈O

colourless, and flammable liquid with strong odour, often used in washing systems; unlike stronger solvents like acetone (CH₃)₂CO, IPA is more practical solution for removing the uncured resin residue from SLA/DLP parts as it doesn't penetrate parts as aggressively.

J

K

L

LDPE = Low density Poly Ethylene, RIC level 4

LIM = Liquid Injection Moulding

LSR = Liquid Silicone Rubber

 liquid form of HTV; used in Injection Moulding

M

MIM = Metal Injection Moulding

can also refer to: Micro Injection Moulding

MSDS = Material Safety Data Sheet

 

N

NBR = Nitrile Butadiene Rubber

O

P (a-d)

PA = PolyAmideS

commonly known as Nylons, semicrystalline plastic. Most common variants used in Additive Manufacturing are PA12 (example: EOS PA2200)  biodegradable PA11 (example: EOS PA1102), PA6.

PBT = PolyButylene Terephtalate

PC = Poly Carbonate(s), RIC level 7 ♹

clear thermoplastics that can be easily machine worked, thermoformed and injection moulded.

PCL = Poly Capro Lactone

PDMS =Polydimethylsiloxane [(CH3)2SiO]n

also known as silicon oil or dimethicone, it is most widely used mineral organic polymer in siloxane (“silicone”) elastomers. Optically clear, inert, non-toxic and non-flammable, FDA-approved for cosmetic and even medical use.

In context of 3D Printers, often used as a non-stick coating of resin vats and build trays (example: Formlabs' Form2 SLA printer)

PDVF = Polyvinylidene fluoride

semi-crystalline, self-extinguishing thermoplastic resistant to many harsh chemicals. Discovered in Japan in 1969 by Dr Heijji Kawai. Suitable for injection moulding, compression moulding and hot moulding, recently it started to appear as specialised filament for industrial applications for FDM/FFF systems. 

P (e-l)

PEI = Poly Ether Imide

stong heat and impact resistant plastic, cheaper alternative to PEEK with slightly decreased properties; suitable for CNC and injection moulding

starch-derived polyester (NOT acid)

PLA/PHA = Polylactide and polyhydroxyalkanoate blend

blend of bio-polyesters suitable for desktop 3D printing. PHA additive counteracts brittleness of PLA, resulting in slightly stronger parts. First developed by Dutch company ColorFabb, sister company of Helian Polymers.
