Keywords: Slider, Manufacturing Process, 3D Printing.

Abstract: The transverse slider is one of the components in the 3D machine civil building printing which serves to help

bring the nozzle to the coordinates according to the desired building design in order to produce the shape

according to the design. 3D machine printing Civil buildings require a device designed to be a carrier for other

components. Transverse slider will carry the nozzle with the help of the motor movement, then with the help

of the control the slider will move according to its coordinates so as to help bring the nozzle to the coordinates

of the building design. The construction of the transverse slider on the Civil Building 3d printing machine is

carried out by machining and fabricating the parts such as lathe, milling, grinding, and welding. After the

Slider is completed and realized at the Bandung Manufacturing Polytechnic Department of Manufacturing

Engineering, it is hoped that the Slider can be used for the manufacture of civil buildings and function properly

and be useful for the Polman academy, and the State of Indonesia.

1 INTRODUCTION

Along with the times, the manufacturing industry is

always developing continuously so that advances in

manufacturing technology can simplify and speed up

the production process, as well as its relation to civil

technology that applies the Additive Manufacturing

method by means of 3D Print for building

construction. Additive Manufacturing is a

manufacturing process by adding material in layers so

that it can form something called finished product,

this building construction can be operated by 3D Print

which processing time is relatively faster compared to

manufacture by human labor.

3D Print building or 3D building concrete casting

machine (3D Concrete Building Printing) has a

working principle similar to 3D Print in general,

namely the FDM type, where the building to be

printed can be formed by adding concrete material

and removing it layer by layer through a nozzle whose

movement is operated by the program. 3D Print this

building requires nozzle for Secrete ingredient

geopolymer which becomes ingredient building, so it

is necessary sliders for bring nozzle to the desired

coordinates so that the designed building could

formed.

The working principle of the 3d printing

transverse slider for civil buildings is that the servo

motor will rotate according to the direction of the

computer. The servo motor will turn the gears on the

rack gear to move Slider according to coordinates.

The slider will bring the nozzle to form the desired

civil building design.

2 SOLUTION METHODS

In this solution method, it begins by making design

based on found references. After To do planning start

the planning process making about how sliders this

will made. After planning done so start at stage

material procurement, material procurement is

divided into 2, namely standard materials and non-

standard materials. On standard materials done QC

for knowing can the material used for construction

sliders machine 3d printing Building Civil. On non-

standard materials apply machining process for make

the desired part, after that then the part already

through the machining process enter Step QC for be

measured can parts used in construction sliders.

After all parts collected so start assembly process

is carried out or assembly for shape construction

sliders transverse. After the construction is done

assembled, a trial is carried out on the slider

construction to find out whether the slider can

function properly or not.

Slider already experience trial stage and test

results obtained that sliders could used for

construction machine 3d printing building Civil , then

the manufacturing process sliders transverse done.

2.1 Design

Slider transverse is the slider that brings the nozzle to

the required coordinates, the placement of the

transverse slider on the construction of a 3d printing

machine for civil buildings as in the following

picture:

slider is on the x-axis carrying the nozzle to direct the

nozzle to print the geopolymer according to the

desired design.

The design for the transverse slider is made as
