Hi,
While I think I understand what some of the posters here are saying I think that I don't fully agree with some of their comments.
On the one hand I do agree that anything that you can print from home on a relatively inexpensive printer will likely not be as "clean" or "well defined" as something that you can get done by a service (like Shapeways). However, even the stuff that I have bought from Shapeways has required some degree of clean up, especially with regards to the "striation" and other "artefacts" from the printing process.
In general I have found that with regards to cleaning up these type of print "artefacts" can be very difficult if you have a complex 3D printed shape. As such I have found that although you can potentially print a complex model as a single "piece" a lot of times it may actually be better to break a model into smaller assemblies that are easier to "clean" and "surface prep" prior to assembly into a single larger unit.
With this in mind I have found that even my older printer can still be of a great use to me. In a lot of ways I view my 3D printer more as a "scratchbuilding assistant" than as a "parts replicator" since I know that whatever I print will require some clean up and additional work after its printed. But it has been very useful to me in trying to assure that whatever I have printed is reasonably correct in dimensions and layout.
For instance, I have used my 3D printer to:
- make a rough shape for a 1/60 3D astronaut for a build. It eventually required a lot of putty and sanding/sealing, but by starting with a scaled 3D model that I downloaded off the internet I was able to make sure that what I was starting with had the proper dimensions and proportions, etc.
- Similarly, another time I 3D printed the rough "framework" for some sponsons that I wanted for a small aircraft carrier kitbash, and then covered those "frames" with sheet styrene, which I found easier than trying to build the "frame" out of styrene shapes, since there there were a number of varying dimensions, angles and such that I suspected might be difficult for me to cut and assmeble properly.
- In addition to those however I have also printed a couple ship hulls, that I then coated with balsa filler (and/or putty) and sanding sealer, which I then sanded smooth.
In each instance I could have potentially instead tried to completely "scratchbuild" the items the old fashioned way (such as building up a hull by tracing frames onto wood, cutting them out, assembling them, and then "planking the frames") however the use of my 3D printer has allowed me to greatly "simplify" alot of the steps in "scratch building" stuff in my model building.
