This document summarizes the development of a low-cost 3D printer using fused deposition modeling (FDM) technology. FDM is currently the most commonly used 3D printing method. The proposed printer would have a build volume of 200x200x200 mm and cost around $20470 to produce, making it significantly cheaper than comparable FDM printers on the market. It uses many 3D printed parts and acrylic sheets to lower costs. The goal of the project is to make 3D printing more accessible by developing an affordable, portable FDM printer using a simple design.

1. “Development of low cost
fused deposition modelling
(FDM) 3D printer”

2. Additive manufacturing
or 3D printing
● It is a method of
converting virtual 3D
model into physical object
● where a 3D object is
created by laying down
successive layers of
materials

Why FDM?
Fused deposition modelling is the most used technology (36%), followed by
Stereolithography (33%) and Selective laser sintering (25%).

6. What is FDM?
Fused Deposition Modelling (FDM) 3D
printers use a thermoplastic filament,
which is heated to its melting point and
then extruded layer-by-layer to create a
3D object.

13. 3D Printing Applications

14. The machine is smaller hence space
is saved.
The machine has more build volume
compared to other printing machines.
The number of parts used in the
machine is reduced hence bringing
down the cost greatly.
The machine is portable.
Cast acrylic sheets are very brittle.
Limited number of materials can be printed.
As the complexity of the part increases the
time required to print also increases.
ADVANTAGES DISADVANTAGES

15. How is it cost effective?
Conventional printers make use of aluminium extrusions which makes
it expensive.
Most of the parts in the machine are 3D printed from PLA in order to
cut cost.
Acrylic plates as body panels are used for effective weight reduction
also making it cheaper.
CoreXY technique can be implemented with only three structural
plates, all of which can nest during fabrication. It is fast and flexible
which saves time and is economical.
