PRICE BALANCE - ~$2,000 sounds expensive but as it is in kit form, if you build in with care, consider the actual "real" value of the kit to be >$5,000.
KIT BUILDING - Built in less than 25 hours, my background is doing this sort of thing so found it easy, enjoyable and satisfying. Documentation and support is brilliant. Important thing is to take your time with the build and you should have as good of experience as I did.
PERFORMANCE - astounded that the first prints were simply perfect, and they have been getting better ever since after tweaking and playing with various settings and techniques. Have printed using PLA, ABS, Nylon, metal composites and various others with success.
USE - Mostly used for custom engineering items to support my projects rather than getting a fabricator to make them (at great expense and time). You can design and build with an FDM that has as much strength as a cnc fabricated item. Yes, built a lot of kids stuff and home solutions too. The printer was paid for by project income in the first 3 months of service.
RECOMMENDED MODIFICATIONS - Remembering the Max V3 is now available, much of my modifications and upgrades are incorporated in the V3 model already. Essential modifications I have made include:
- Temperature enclosure - I simply housed the printer in a melamine cupboard so the printer generated heat stays around the printer. No need to go fancy with an enclosure.
- Build Surface - Tried everything, now using PEI sheet which works perfectly with the problematic ABS. The PEI sheet is stuck directly on the glass build plate but suggest the PEI sheet on an aluminium or copper sheet would be better to allow heat spread to be more even.
- Extruder - standard extruder worked fine but wore out (started to slip) after huge number of hours of use (18 months of almost full time use so can't really complain). Upgraded to the Bondtech extruder which has a far stronger performance. Easy upgrade to do.
- Hot End - wanted to start using higher temperature filament so upgraded to the E3D V6. A bit of messing around to fit but perfect results straight away. Only issue I have is that PLA tends to clog in the E3D V6 a bit but that is manageable. I mostly print in ABS and ABS variants anyway.
- Delta Arms - Upgraded to the SeemeCNC ball cup arms. Easy to do and makes the assembly much more stable.
- Carriages - Upgraded to the SemeCNC injection moulded carriage set. Improved assembly stability even further.
- Lighting & Camera - sounds unimportant but adding some COB leds and a HD camera to the printer is useful as I can then keep an eye on prints without going into the workshop and opening the temperature enclosure.
FUTURE UPGRADE ASPIRATIONS - Although the Max V2 printer is doing a wonderful job, I can still see that more improvements can be made. Some noted below.
- Upgrade temperature enclosure - I will be changing the enclosure so the electronics base is dropped below the floor of the enclosure. This is so I can keep the electronics cool but be able to actively heat the entire chamber to >60degC.
- Upgrade microcontroller - not sure what to yet but aim is to improve resolution of prints.
- Dual hot end - with the aim to print using dissolvable supports through one hot end and ABS through the other. I'm not interested in colour mixing as I already have another Delta printer to do that using a Diamond mixer hotend.
The Max V2 is a joy to use and I can quite happily watch it do its thing all day. It is one of those oddly satisfying things to watch.
