3-D

printing

technology

was

first

developed

in

thenineteen

eighties.

But

high

cost

put

them

out

of

the

reach

ofmany

researchers

and

businesses.

Early

printers

were

limitedHigh

cost

market

wassmall.

Now,

lower-cost

printers

are

available

to

a

much

widermarket,

including

small

businesses

and

individuals.2What

is

3D

Printing?3We

all

know

what

printing

is

so

let’s

begin

with

the

3D

part

of

3D

printing.

3Dis

shorthand

for

three-dimensional.

When

you

print

a

page

on

a

printer,

there

are

onlytwo

dimensions:

the

front

of

the

page

and

the

back

of

the

page.

Three-dimensionalprinting

adds

a

third

dimension,

volume.3D

printing

uses

a

printer

to

create

three-dimensional

objects,

for

example,

acup

or

doll

or

phone

case.3D

printing

has

these

qualities:4Objects

are

created

by

adding

or

depositing

layers

of

material,

not

subtractingcutting

out

pieces

from

a

block

of

material.Because

objects

are

created

by

adding

layers,

the

computer

file

with

detailsabout

your

model

must

be

converted

into

slices

the

printer

will

create

layer

by

layer.Printing

a

three-dimensional

object

can

take

hours

or

days

to

complete,depending

on

the

complexity

and

size

of

the

object.Cost

is

based

on

materials

used,

among

other

factors.

In

contrast,

if

you

buy

apiece

of

wood

then

cut

out

pieces

to

create

your

object

you

pay

for

the

original

pieceof

wood.How

3D

Printing

is

Used5Today

3D

printing

is

mostly

done

by

business,

students,

and

designers.

Home

or

consumeruse

of

3D

printing

is

mostly

limited

to

people

trying

out

the

technology.

However,

there’s

a

loof

value

in

printing

three-dimensional

objects

for

students,

designers,

and

anyone

who

needs

asmall

object

to

demonstrate

their

ideas

or

create

usable

objects.

Students

as

young

as

10

yearsold

also

might

use

a

3D

printer

in

shop

class.It’s

the

future

uses

of

this

technology

which

have

people

excited.

For

example,

replacingthe

plastic

back

of

your

TV

remote

might

involve

going

to

a

website,

finding

the

part,

thenclicking

a

button

to

have

the

part

printed

locally

where

you

can

pick

it

up.

Today

you

eitherreplace

the

complete

remote

control

or

figure

out

where

to

get

the

replacement

part

which

hasbeen

created

elsewhere,

likely

overseas.More

interesting,

3D

printing

makes

it

possible

to

experiment

with

fashion

and

other

partsof

our

lives

we

take

for

granted.

might

be

possible

to

create

medical

implants,

for

example,using

tissue
