What is 3D Printing
3D Printing is an Additive Manufacturing technology that creates 3d objects by building layer by layer.
Build volume : 25 x 21 x 21 cm
Layer height : 0.05 – 0.35 mm
Max travel speed: 200+ mm/s
Max hotend/heatbed temp. : 300 °C / 120 °C (572 °F / 248 °F)
Supports only a 1.75 mm filament.
3D printing filament is a type of plastic called thermoplastics that becomes flexible when it is exposed to heat with the right temperature. This material allows the printer to create different shapes by forming the filament before it cools down.
1- ABS Filament
2- PLA Filament
3- PET Filament
4- PETT Filament
5- Nylon Filament
6- PVA Filament
7- Sandstone Filament
8- Wood Filament
9- Metal Filament
10- HIPS Filament
11- Magnetic Iron Filament
12- Conductive Filament
13- Carbon Fiber Filament
14- TPE Filament
15- Glow in the Dark Filament
16- Amphora Filament
OK, We have 3 types of 3D printers in the lab, CR-10, Ultimaker 2+extended and Prusa MK3s.
the one that I am using almost all the time is Prusa, for all the specs and extra futurs that are available in it. I also have Alfawise u20 in my home, just as hoppy printing and so on.....
Now let's go with prusa MK3s specs :building space (25 x 21 x 21 cm)
filament size (1.75mm)
Layer height start from 0.05mm
support for a lot of materials PLA, ABS, PET, HIPS, Flex PP... etc. , we usually use PLA..... the nozzle and bed can also support all these materials with a variety of temperatures
Heated bed
what else.... there are alto to like in this printer, and for more info please check this link: Prusa MK3
most of use are using Prusa for printing, so all the team agreed to work and test prusa sitting, and what else to search on for STL file that the grate Thingiverse (All In One 3D Printer test)
scale test
overhang test
hole test
diameter test
bridging test
We are using PLA filament and 0.4mm nozzle:
how to use the slicing software Prusa Slicer
first what are slicer softwares? They are a converstors from 3D objects that we design in 3D design softwares like onshape and others to a layer that the 3D printer can understand and work on..
We are using this sitting for printing with .2mm lighter height (can be described as the resolution of the print), then the filament we are suing (PLA), printer type, if there is any need to add support or not and finally, how much material we need inside the print (20% of the print is filled) :
with the previous sitting, the slicer is giving the following needed time, materials info for the print:
It will take 4h and ~40m and it will use ~50gr of filament Save "Export G-code" and go to the printer
Printing, layer by layer....
after printing, we saw some problems with the finishing...
As you can see, there are some thin lines between the parts flying,Scaling was not perfect as well. with error of 6% for X with fast printing sittings and 0.2mm layer height almost all other things were good
