Expactations vs Reality
Renders are very easy to create and are usefull to visualize a project in its early stages.
But they do not mirror the flaws and cosmetic defects, which will surface during 3d printing.
SOooo... --> DISCLAIMER/WARNING: Take past & future Renders with a spoon of salt!
Here are some examples for cosmetic defects that will occur during 3D printing:

For your information: most of these defects can be corrected through sanding or ironing with a soldering iron.
2. Prototype summary
Printing with ASA this time brought me lots of troubles, mainly because of the high temperature printing.
I was met with a lot of lacking bed-adhesion and underextrusion problems, resulting in lot of scrapped parts & wasted time
.
What I learned: never save on bed-adhesion glue-sticks!
In conclusion this "Project" has mainly four chapters:
1. Printing
If you trust your 3D printer you could print everything out in a week of time, initiating a print every 12 hours.
12 Prints x 30 min initiating time + 2x 60min scheduled maintaince = 8h |
2. Processing BTW I skipped this part
Freshly printed parts always have some small defects.
You have the option to sand them down, which is very cost effective, but time-consuming(15 min per part ~3h).
Second Option: use an electric hand sander ~1h.
TIP: Assemble the Case before Sanding --> sand only protruding defects --> uniformity
Third Option: use your (unavailable) Woodwork-(200€), NC-(500€) or CNC-router(2000€) with a flush trim bit <1h. I want a CNC too |
3. Having Fun Assembling
Now you have all the needed parts and you can start assembling your case. |
4. Modding
- Want to add another Radiator? Print yourself an expansion module!
- Want to change the look of the case? Design yourself your sidepanels!
you got the hang out of it! |
I will put the printfiles online after some small tweaks.
Printtime: ~110 hours
