Test the rules of your printer

Test the rules of your printer I fist wanted to do a quick review of the different printing options that exist. our test will be done on

Ultimake 2+

Sindoh 3DWOX

for used a model I found on Thingiverse so that i can test abality of our printer capacity on making overhang, bridges, support,etc under this condition for Ulrimaker 2+

Nozzle & Material 0.4 mm ; PLA

Profile Hgh Quality -0.06m

Infill light

Enable support ticked

Build Plate Adhesion ticked

and this is the result i obtained
the bridge was so fine and the support was to hard even to remove them from the model was a difficult thing. But the inner surface was not smooth as i wish, this happens because of jumping of the nosal from one part of the model to another one

again We used two model to test our print on how acculacry we can have on different models to we took two scanner models one for mine and another for my classmate Denis

all model was printed with the same settings but in different printer

temperature testing

Ultimaker 2+ temperature testing

i printed this model under this setting as shown in image below

the result i found was not real good as i want what i realise i that it is not good to use higher temperature according to material used because it also take too long to cool down that cause deformation in model while it is colling down and it better to change the printing speed too beacuse all varies and play a big role in printing quality of a printer, this speed and temperature reduction can be also used solve the problem I faced in first test i mentioned above.

some problems on ultimaker2+ i faced with in this week and how i fixed

most of time the filament feed on ultimaker user gear to push the filament this feed is located at the back of the printer and some time can cause the material to be grounded down by the feeder to solve this problem i refered to the

ultimaker resource and i followed all steps and the problem was solved perfect you can find even some other common problems happen on ultimaker and how to solve them on ultimaker troubleshootings

while i was documenting this assignment i fund another rare problem on ultimaker 2+ that happen to one of our member while his was priniting his model finaly the model was inclined at a given angle relative to the building plate while when he was designing his model, the model was supposed to be vertical he called me to help him on this problem and honestly it was my first time to see this what i did i check the nosal and i found that may be there is some thing move it but i dessembly the nosal part and ressemble again but finaly i realised that that was not the cause because even if the nosal is not alligned well but the vector travel can not be changed now i check the movement of the X and Y axis of motor final on X axis pulley was not tight fixed so in moving backward was not actually completing the steps but in forward was working fine what i did i tight the pulley screw again using mini L shaped allen keys(hex screwdriver L shaped) and now is the printer is working fine but in dis trouble shooting i forget to take photos or video of the process but the pulley i fixed is this none

while i was making some research i fund another problem that happen to me seval times before when i was using thin walls of the material
to solve this before i haven't any idea but on this webpage of ultimaker community one person was suggesting to use Slic3r Instead of cura but this topic was in 2015 but in nowdays cura is supporting thin wall too no need to worry about this again

3D Printing

in 3D printing i created a model in solidworks because the solidworks is especial for CAM(Computer Aided Manufacturing) and it can be used in 2D and as well as 3D design its simulation is awsame but I tried to make a simulation in solidwork student version but not thing obtained may be it due to lack skills but am going to contunue working and learning hard and i test and I print It, the design i made in a hallow cylinder with twisted gaps on it vertical body and sperical ball inside

here there is the process i used in solidworks firstly I created a circle on top plane and I Extrude boss/base. After that I extruded cut a rectangle on the body of cylinder and i make a circular parttern to produce more features on body of cylinder. and i closed the upper part on the second design i made i draw i semi circle touching on a centerline on plane and i made a revolve boss base in order to have full sphere and i amde an assembly of those parts and final i obtained a final model and stl file and we used sindow to print this model, below there is the images showing the process of i used:

draw a circular base with 35 mm diameter

extrude boss base with 68 mm of height to get a fine cylinder

create a wall thickness os 2 mm by using shell feature and shell inside by 2 mm

draw a vertical rectangle extrude cut through the wall to create a gap through wall

by using circular parten you can duplicate the gap on circular path with relatice to the origin or circunference of the base

by passing thought insert option then feature you fund flux feature with give you option of twisting on this model i twisted by 270 degree after that i created a top cover with the same setting as base 35 mm diameter

to create a sphere in solidworks i used a semi-circle and i used rouft boss base to create a circular extrusion

my sphere

making an assymbly to create a complex structure that can not be done separately

print setting i used to print this model

3D scanning

within the 3D Scanner we used 3D sense scanner to scan ourserves in time i was making this assignment report i lost same of my screenshot within scanning process so i decide to make another scanning process but i didn't print it because i had already printed the first one so the printed image is deferent from the scanning process snapshot images here there is the process i used in 3D scanning.

• Connect your scanner to your PCusing long USB cable
• Open sense software
• Choose what you want to scan and start scanning
• share you scanned model or either save it and print

configuring Sense software

after downloading and installing the sense software open its and wait for booting

choose the language you prefer

connect your scanner to your computer and wait abit to be detected

activate you scanner by cliking on I have an activation code if you do not have activation code click on Get activation Code From Cubify.com

i struggled to get the key because the personal the scanner was on his name was not around i spend more than two days by contacting on cubify in order to change the name finaly I got the activation key

enter your activation key and click on activate

watch some tutorials at the beginning on how the software used of you want if you do not want you may skip it no problem

have look on same useful mouse and keyboard commands

here we go

choose what you want to scan on my self i choose human

choose head or full body depend on what you want

this scanner they do not make make full body perfecty i prefer to use it on object scan or head

Start scanning by clicking on start

move around the person or object slowly until you have all details in your scanner software

edit same missing part or remove the unwanted part in your file

you can make some few advanced editing like colorinng,trim and touch up

you can share your scanned file directly or save to your computer for future use

save the file

import the file in cura for 3D priniting

start printing

i got some support on my chin

final 3D printed body

3D printing limitations

material limitation

all filament or filament combinition can not be using in any print like ultimaker 2+ we have in our lab check on material compatibility

build volume limitation

the lastest of ultimaker 3 extended can that print large volume print only 215*215*300mm while the ultimaker 2+ we have can print only 223*223*205 mm, check on 3D printer comparison even Sindow 3D wox have almost the same problem of build volume limitation

connectivity limitaion

i said the limitation by comparing between ultimaker 2+ and Sindow 3D wox ultimaker can be interfaced with a computer using ony usb cable or SD card which means that if you do not have one of cable of sd card you can not use ultimaker 2+, while on sindow you can use even wifi to send file and other cool feature i like on sindow is the realtime printing streaming by using a small webcam builded in it which is a cool thing you can know where the process is reach in realtime even if you are in remote connected to the print

temporary memory

every thing am describing here are some missing for both ultimaker 2+ and Sindow 3D wox on sindow this problem is solved some how because if a printing process you can remove a device either cable or USB memory stick and continue using your memory in other use without any problem but on ultimaker if your are using cable on your computer with ultimaker you have to wait until a printing process is completed which is shamefull in case you using your portable laptop
