Once the prints are excavated, the powder remaining in the printer bed is vacuumed and recycled for future builds. The prints, especially if there are small features, can collapse under the weight of the excess powder if a thorough enough vacuuming isn’t performed. The 3D prints are very fragile and would easily crush in your hand if you applied force. Models are buried in powder so the vacuum sucks up the powder until enough model is exposed to very carefully move it into the attached de-powdering station. When the models have finished “drying”, they can be pulled from the printer bed and post-processed. The drying process helps the binders set so that the models are more robust for the post-processing step.
Post-print, the models must sit inside the bed of powder for an additional 90 minutes to “dry.” For example, a 14kg container of powder (pictured on the left below) costs $1,100. The consumables are quite expensive as many of them are proprietary to 3D Systems so 3D Systems charges as much as they can. It is advisable to maintain a service agreement on the printer for around $9,000 annually. It is usually recommended to print the 3D models laying on their side as this orients the 3D printing build lines straight up and down the model which helps hide them.Ĭonsumables for the printer you need to keep on hand include: the powder (zp151), yellow, cyan, magenta, clear and black binder cartridges, HP11 print heads, zbond cyanoacrylate (super glue) and waste disposal trays, along with choice maintenance materials including alcohol swabs and distilled water. The quality of the final 3D print is affected by the orientation of the model inside the 3D printer.
ZPrint was freeware made by Z Corporation which was aquired by 3DSystems and repurposed as a 3DSystems print utility for use with full colour printing.
The 3D printer is controlled by ZPrint software, which allows you to import models, position them in the build and start prints. It is also sometimes difficult to come by 20A circuits in office spaces and the printer has a vacuum cycle that runs every few minutes that produces a fair amount of noise. 3D Systems Projet 660: Everything you need to know about operating the printer
