Post 3D Printing 101

For someone who is new to 3D Printing...
Where should one start?
Which software / hardware / printer should one start with?

Pretty subjective but my 2 cents

Here is generally how i got started last month.

1st coming up with a general budget that you might consider spending and what size of work you might want to do and what you might want to print for (toys, functional parts, etc). Printer costs vary from a few hundred to millions of dollars and everything in between.


2nd narrow down a list of a few in that range and check out youtube and online reviews to see how they fare. There are alot of good reviews out there on all the major printers and kits.


3rd concurrent to all of this checkout thingiverse to see what is available to print as well as download a free modeling software - something like fusion 360/sketchup/etc. and try drawing. If you dont like the modeling then your likely going to hate printing unless its just files your finding online. From here you can decide what software you need to buy (if any). I am using a free version of sketchup and fusion 360. The slicer is Cura which is also free but there are software packages that do offer more features later that i might purchase.

For me i use autocad/revit occasionally at work so getting into sketchup and now fusion 360 really hasn't been a big deal. I wanted to spend no more then $300 and i wanted to print around 220mm square. My goal was to print functional parts for things like RC cars as well as a full scale kit car so i wanted to be able to print in a variety of materials. I ended up with a Creality Ender 3 Pro for around 210.

Hello,

I have a Zortrax M200 FDM printer. It's not cheap but could print beautiful.
It has a own slicing software. Very easy to use. It prints with 1.75 ABS filament.
Nozzle diameter 0.4 mm

Some rule of thumb according to my FDM experiences:

- Offset by holes + 0.3-0.4 mm in diameter

- Against warping you have to make permanent temprature. I covered my printer with a simple cartonbox.
For me this cheap carton solved this issue.

- Minimum wall thickness must be 1,2 mm rather 1,5 mm by the main body of a RC car for exaple.
I always had problems with parts, which had smaller.

- By functional parts for exaple suspension bars, minimum 2-3 mm rather 4-5 mm
But for sure you cuold stregth them with more infilling.
Normally 30-40 % of infill is enough.

I just bought my first 3D printer and it’s being shipped right now. If you are looking at an Ender 3 Pro then take a look at the CR-20 Pro also. It is the same as the Ender 3 Pro, but it has a better extruder, Capricorn tubing, BL auto bed leveling, a newer control board. It also comes basically completely assembled. 4 screws and you are ready to print. It also costs less than an Ender 3 with some of those upgrades. I bought it because all the reviews I have seen which say the Ender 3 is a great machine and even better with a few upgrades. The CR-20 Pro is ready and has all the upgrades out of the box. I got mine for $315.

3D Printing is great fun! Get Tinkercad to start. It's free and very easy to use, and to make basic parts. I use Cura for slicing. The printer I have is called the Monoprice Maker Select for $240, assembled. It is a copy of the Wanhao Duplicator i3, which has prooved to work very well. I did the Z-Axis stabilzer mod and glass bed, which made big differences.

I have liked it alot. I did some basic printed mod's like the filament guides. I probably have about 1.5 KG of material through it and its been solid. A few failed adhesion issues with PETG and the factory bed material. I purchased a glass bed and that has cured those issues.

I like the CR-20 pro that was mentioned especially at 315 bucks! When i bought my pro it was 209 shipped and i think the 20 pro was another 150 bucks. But for me i dont need a filament sensor and i personally like to level my bed by hand - its not difficult and i only do it maybe once every 5 prints just for good measure. Putting together the ender 3 was fun as well. If you like building model RC cars then I see it as a bonus to actually assemble the ender 3 (about 2 hours and watch the youtube video while you do it for all the tricks).
