I’m fairly new to the 3d printing community and I loved the recent video out out by Tom on the cost of cloning the MK2. I have a question though. Are the any similar clone guides out there for a printer with a larger print bed . I’m hopeing to print in the 400 to 500 mm range all xyz so a prusa cr 10 super clone. Does anyone have any suggestions or point me in any directions. Thanks for any help you can give.
Hi OSUWOLF, nice to meet you.
You can always go through the following pages
Most of the Machines come with a GitHub Repo or some tutorials on how to build them
Welcome to the forum. If this is your first build, I would suggest you keep the print size to a more manageable 200mm range for a few reasons.
- Cost. A bigger bed is more expensive and will require a larger power supply.
- Rigidity. Larger printers must be stronger and have tighter tolerances. They will be less forgiving than a smaller printer.
- Maintaining temperatures. Ideally, a bed will have a uniform temperature to promote better adhesion. Finding a quality bed is tough enough at smaller sizes.
- Leveling. Similar issue to temperature. Beds are not perfectly flat, and definitely warp a bit when heated. Bigger beds may be more challenging to level (though not impossible).
- Weight. A more massive bed could cause artifacts in prints at higher speeds (tunable, but will be more work).
Building a bigger printer is certainly possible, but I imagine it will take quite a bit more work to get satisfactory prints. Prop makers on u-tube often find ways of designing large prints in multiple pieces rather than going bigger.
Either way, you’ll learn a lot and we’ll be here to help and cheer you on!
I appreciate the feed back and understand your advice. What if I went the other direction. Do you have any suggestions for a printer that prints small but very accurately, around 100mm xyz? Something I could start with before I work my way up to large prints.
The funny thing is that smaller in this case won’t necessarily be cheaper or more precise. My first printer was a Monoprice Mini. It has a print size of about 130 x 100. I used it to print all the parts of my first i3 clone, minus the controller cover and spool holder (the clone printed its own!) I really liked that printer and it was under $200 US.
For a little more than that, you might consider an i3 clone. Specifically, mk2 parts on a mk3 frame.
Ty for the insight. I really appreciate it, I will pick on of the mk models to start with. Ty
