Pricing, Staff Workflow, & Application Development for 3D Printing Service: Achieving the Best User Experience
Download as PPTX, PDF2 likes619 views
This document discusses best practices for pricing, staff workflow, and application development for a 3D printing service to achieve the best user experience. It recommends a time-based pricing structure of $1 per hour plus a $2 per print fee. It outlines a staff workflow with a journey map showing the process from job submission to completion. It also stresses developing easy-to-use applications to support the workflow for both users and staff.
![1.Pricing - Cost Factors
• Equipment wear/tear & eventual replacement
• Purchase amount and refresh cycle
• Electricity
• Staff time & expertise for service and maintenance
• Per print
• Filament (and other consumables)
• Proportionate to use
• $43-48 for ABS/PLA and $65 for dissolvable per 0.9 kg [2.00 lb] from
Makerbot](https://image.slidesharecdn.com/acrlpricing2017-170324042510/85/Pricing-Staff-Workflow-Application-Development-for-3D-Printing-Service-Achieving-the-Best-User-Experience-4-320.jpg)
![Calculate Away
• 3D plastic filament is $48 for ABS/PLA and $65 for dissolvable per
0.90 kg [2.00 lb] from Makerbot.
• $48/900 gm = $0.05 per gram - ABS/PLA
• $65/900 gm = $0.07 per gram - Dissolvable
• So on average, 6 cents per gram
• For an hour of 3D printing time, 0.26 x 60 min = 15.6 gm per hour.
• 15.6 gm x 6 cents = 94 cents per hour
• Roughly $1 per hour of 3D printing time for the cost-recovery of
filament only.](https://image.slidesharecdn.com/acrlpricing2017-170324042510/85/Pricing-Staff-Workflow-Application-Development-for-3D-Printing-Service-Achieving-the-Best-User-Experience-16-320.jpg)
![Upon the Visit: Using the 3D Printing Service
• Get the 3d print estimate (time/filament)
• Submit the 3D print job (upon the acceptance of the cost estimate)
• Confirmation of the job submission to the user.
• Notification of the job submission to the staff.
• [Model 3d-printed]
• Update of the job status.
• Notification to the user and the staff.
• Record of payment and pick-up.
