sorta curious, how long was it before you got your first order, and do you have any tips to that help you get the word out,
and two if I am having warping issues with abs I use hairspray and whatnot will pla be better or worse as far as warping?

Regarding first order, it took a while. Of course I’m in the Seattle area where there are a lot of folks with 3D printers, so it’s mostly a matter of how close your customers are. Also, what equipment you have. One of my customers has his own 3D printer but uses my service because his own printer simply won’t do the job. I expect he’ll eventually just upgrade printers and won’t need my service any more.
Regarding warping, I’ve had much, much less problems with PLA than with ABS. Heated bed makes more difference than hair-spray for me. And orientation of the print. I also found that using a raft helps too.
My first order was two months after setting up my hub, mainly I think because my prices were very high. I reccommend adding pictues of prints and your setup onto your hub for more attention.
As for warping PLA warps a lot less than ABS. I use a heated bed at 110c and a glue stick. I found that a lot better as you can concentrate the stickiness to one area. I sometimes have to use a raft for small objects though. It’s all about trial and error with your printer!

I find that a heated bed is not needed with PLA. Often I will wipe down the blue masking tape with rubbing alcohol to get really good adhesion. Things that have square or rectangular footprints want to curl up/lift so I always put a Brim around that first layer. I have also added circular pads (1 -2 layers thick) on each corner to increase the surface area touching the build plate. This has solved the problem for me when working with models that really want to warp. If need be, you can create a box that will help shield the print from drafts and temperature changes (usually not necessary with PLA). Also, it is helpful to store your filament in an air tight container out of sunlight, and keep it CLEAN. I am convinced that one of my spools became unprintable due to moisture and dust. It’s always a good idea to check the calibration of your printer bed if there are problems getting prints to stick.
I agree with the others that posting photos of objects that have come off of your printer is what would convince me to go with one provider or another. If possible show a “torture test” model - something that is either very precision (take photo with ruler or something to showcase accuracy) or something with overhangs, nooks and crannies or connected movable parts. Showing one or two different finishes on prints will also make you stand out and possibly get more orders. It certainly would convince me!

Some PLA does warp more than others but I really think you should test colorFabb PLA/PHA. The warping effect is almost non-existent. And if you want to have tougher objects, consider XT and XT-CF20. They should easily replace ABS for many projects.
Concerning the first order delay, it depends a lot on how you “sell” your hub and how many potential customers you have in your area.
- You should consider adding as much different HQ photos as you can (which I need to improve for Gloomy Spark)
- Think about the price you set
- Participate to special communities prints (do not know how 3DHubs call them) like the Fairphone cases prints
- And cherry on the cake if you have time: do some Marketing! 3DHubs is not a customer provider, but more a customer facilitator
- participate / create events near your hub
- print flyers and place them at strategic points like technical schools, art galleries, …
- get involved into Fablabs’ life
- …
Thanks for reading!
