Definitely agree. I have accidentally left a couple of Shapeways items in Bestine, overnight. One was truck frames. They literally crumbled.
Hi Dave did you ever find out what glue is best to use? I have some etched brass walk ways I need to fix to some Shape ways coaches....can anyone advise what glue to use?
Jason, At work, I use JB Weld, or JB Clear Weld. I like it better than Zap-A-Gap or other super glue brands when gluing SLA parts together or with other materials. Scott
I just got a building interior I printed at Shapeways in their fine detail resin/plastic. The current guidance on their website advises either a soak in hot-ish (170-180) water with dish soap for a few hours or a dunk in an ultrasonic cleaner. That is supposed to clean off any oil and wax residue. I have to say my model came back pretty clean already. But definitely no mention of Bestine for this specific material.
Were I work, we bath our parts in 99% isopropyl alcohol from 5-10 minutes, depending on the resin. But that is what the resin manufacturer recommends. I think following Shapeways recommendation is wise. Scott
I use Bestine, as other methods did not do the job. Those included the hot dish soap soak and scrub, plus other modelers suggestions for degreasers. Bestine is essentially a residue/greaseremover, which is what we are doing with what we receive from Shapeways. It might also be worth noting that the materials they and others use now have improved since 3D printing began. So that is also a factor.
Shapeways....The water temperature should be around 70ºC/158ºF. Let the parts soak for a couple of hours, the water may turn cloudy as wax and oil separate from your models - you can repeat this process without harming your parts if necessary. You can also use an ultrasonic cleaning machine, or dip the models in acetone for about 5 minutes - if you choose to try acetone, make sure to clean the model thoroughly when you're done soaking. https://support.shapeways.com/hc/en...aning-and-painting-Fine-Detail-Plastic-models On that page they do mention acetone and if you look at peoples posts elsewhere you often see people preferring either Bestine or acetone. Looks like a personal choice, some liking one others like the other. The other possible fly in the ointment is that if I understand it right not all Shapeways prints are from the same material. The Doodlebug drive gears I just got are in smooth white and James who designed them recommends... If printed in the Smooth Fine Detail Plastic materials it will require cleaning before painting. I recommend washing with warm soapy water then soaking in 'Goo Gone' or a similar non-corrosive product for 24 hours. Then rinsing off with warm water and allowing to dry. He has that on the page with the gears but I don't plan on painting them so think it is his general recommendations that covers his other items such as loco shells. He is in the UK and from reading other posts on the subject 'Goo Gone' is a choice there as they can't get some of the other alternatives. Kind of pick your poison situation, Sumner
