One of the biggest lessons learned by first time 3D printer users is that not everything can be replicated and a printer is a machine and not a miracle worker. It has limitations in terms of what it can print as well as the quality of the output. For teeny tiny objects, the 0.8 mm nozzle will just not do and with resin printers on the rise, the question is, ‘are extruder printers obsolete?’
[Dorison Hugo] has made a mini version of the PS One using a Raspberry Pi which you can play games one. The kicker is that in his video, he does a comparison of an SLA printer and a cheaper extruder one for his enclosure. He goes through a laundry-list of steps to print, file, fill, repair, sand paint, sand, paint etc to try to get a good model replica of the original PS One. He then proceeds to print one with an SLA printer and finishes it to compare with the first model. The decals are printed on an inkjet for those who are wondering, and there is a custom cut heatsink in there as well that was salvaged from an old PC.
Spoiler alert! The SLA wins but in our view, just slightly. The idea is that with enough elbow grease and patience, you can get pretty close to making mini models with a cheaper machine. The SLA print needs work too but it is relatively less and for detailed models, it is a much better choice. We really enjoyed watching the process from start to finish including the Dremel work, since it is something that is forgotten when we see a 3D print. Creating something of beauty takes time and effort which stems from a passion to make.
Take a look at the video below of the time lapse and for SLA printer fans, have a look at the DIY SLA printer which is a Hackaday Prize Entry this year. Continue reading “Finishing A Mini PS One: SLA vs Extruded”
