Re: 3D Printing

I have an Crealty Ender 3 from Banggood. It came as a kit cost was about 170.00 delivered. You tube had assembly instructions basically very easy to assemble.
I would recommend going to youtube to get ideas on setting up and use.
I have made a series of items that were taken from thingiverse. They include duel paddle key and an Anderson power distribution panel. The keys were gifts go CW friends have received good feed back on them.
Ii have to depend on items published to thinginverse as I am not well versed in the cad programs to design my own.

I've have a Makerbot replicator (dual extruder) and a Prusa I3.  The makerbot is junk, the prusa is great and open source.  

I have printed a lot of pla, abs, and petg.  Work related prototypes, radio parts, eurorack parts, camera parts, and many AR15 and other firearm lowers.  I highly suggest sticking with an open source machine and avoiding the really low end models.  A heated bed is very helpful also.  Dual extruded are generally unreliable.  

The best deal out there currently is the anycubic mega-s, a Chinese clone of the prusa for ~$300ish.

Stick to name brand filament unless you like wasting lots of time.  If your time isnt of value some of the cheaper Chinese stuff is ok to tinker with, but if like me you dont have much free time - buy quality and spend your time enjoying it.

Re: 3D Printing

My son and I have a Monoprice Maker Select Plus and it's been great after two specific upgrades. We replaced the carriage plate with a heavy duty one which made bed leveling so much easier, and added z-axis stabilizers, also contributing to better bed leveling and also overall print quality.

We've also replaced the hot end with an all metal one from Micro Swiss, but that was just so that we could use more exotic filaments like glow-in-the-dark.

As has been said, a lot of it comes down to the quality of the filament used... Hatchbox has been our "premium" filament and Inland our close second.

I'm craving for a Prusa printer but only because it does auto-bed leveling (bed leveling is, arguably, the most tedious but necessary part of printing).

None of the printer really needed adjusting (beyond bed leveling), but a lot of tweaks in the slicer software was necessary to get optimum prints... I used a x-y-z calibration cube model and made one parameter change at a time and printed a new cube. It took the better part of a Saturday afternoon but prints are at high quality now.

I have used a few printers.

I currently use a Ender3 but unlike KR0NS I got way more than I paid for. I have added a few mods to it like a BLtouch and it works great. The overall print quality of any printer is based on more than just the printer.

You will have a learning curve to get the settings right, line width, line height and more.

The filament is another big factor in prints. I have tested more than a few and have found Esun and HatchBox to be worth the 2-3$ over the cheap stuff. Inland has been o.k. too just stay away from amazon basics they are very hit or miss.

The slicer you choose can also make a difference from a good experience and a bad one. I have been using cura and its a good starting software but I will be moving to simplified 3d very soon.

If you take your time learn the machine and what settings do what you will have a good time with them.

In the current market you can get into a solid printer for under 300$. The "you get what you pay for" is not always true in the printing world, just do your research and find one that fits your budget and has a good community.

The DaVinci line has had issue over the years, so has some of the monoprice printers. If I had to buy one again it would be another creality ender or CR10 they are very good and can load custom firmware which is a huge bonus.

Re: 3D Printing

KR0NS
 

I have used two printers.

The first is the DaVinci 1.0 by XYZ printing. It is ABS only and was the cheapest printer available at time of purchase.
Replacing the proprietary firmware made the printer usable (Repetier host + Repetier firmware).
Part finish is not great but usually good enough and I've made many functional parts with it.
The main cost of this printer is in the time that you'll have to invest getting the process and settings, both software and mechanical, correct.

The second printer I've used (but not owned) is the Ultimaker3.
In stark contrast to my experience with the DaVInci, this printer required very little adjustment and those that were required were partially automated.
Find (create) a model, load the (expensive) filament, and print.
It just works. And the prints are beautiful.

At the end of the day you get what you pay for. What you're unwilling to pay for in cash, you'll pay for with your time or do without.

SSS Results

John Lonigro
 

It's too bad only 7 people participated in the Second Sunday Sprint this month. I guess with summer arriving (nearly), there's more outdoor family activity and maybe amateur radio's priority has dropped a bit for some.  Maybe the unsettled atmosphere had something to do with it as well.  However, most of those who participated saw pretty much action.  Carl WB0CFF came in first this month with a whopping 28 QSO points, followed closely by Chas W2SH with 19 and Gary KF7WNS with 11.  Carl will receive his June certificate shortly.

The overall leader for the year is Chas W2SH with 89 points but Carl is gaining fast with 80 points.  Nick WB5BKL is currently third with 57 points.

This marks the halfway point in the 2019 SSS.  Later this month is Field Day weekend.  Hopefully everyone will be able to get out for at least a few hours that weekend and have fun playing radio.

Thanks to the link to your 3 D project. I found 3D printing as additive as ham radio.
Since getting my printer and finding thinginverse I’ve made several items related to ham radio.

It isn't perfect, but it did come out looking pretty nice and sure will keep fingers (and fallen component leads, etc.) out of the exposed wiring as well as look decent on the bench.
