Carbon DPR 10
DPR 10 is a fast, accurate material ideally suited for dental models. Its stone color is appropriate for dental and orthodontic applications.


Carbon’s AO Stack workflow is designed to enable labs to produce additional DPR 10 models overnight, without the need for additional operators to handle print turnover.

Dental CAD software such as 3shape or Exocad must be used to modify dental scans and design the production files.
- CAD programs can use a DME file to ensure dimensional accuracy and part fit. A DME file is a set of parameters that is tuned for specific manufacturing processes and resins.
- Carbon provides a DME for DPR 10.
- The DME file will hollow your models, apply vent holes, add friction bars to die pockets, enlarge die pins, and more.
- You may want to customize these parameters later for your specific needs.

DME settings for 3shape can be downloaded here: 3shape DME Settings for DPR 10

- Recommended wall thickness: 2.5 mm
- This thickness represents a good balance of resin usage, print speed and accuracy.
- Thinner walls could yield less accurate parts that can crack during part removal
- Variable wall thickness functionality is built into dental CAD programs. This feature will thicken walls as the part progresses, yielding fewer islands and more accurate parts.
The Carbon DME file will automatically apply this setting.
After hollowing, parts require vents (known as Side Drain Holes in 3Shape) to allow the free flow of resin and air into the interior of your part during printing. This prevents print failures due to internal vacuum forces within the part, uses less resin, and speeds up prints.
- 2-3 mm in diameter.
- Located at least 1 mm above the platform.
The Carbon DME file will automatically apply these settings.

Vents above platform
- Part is stronger at platform
- Lower chances of cracking during removal from platform

Vents at platform
- Vent can become point of failure during removal from platform
- Chances of cracking increase during removal from platform
HIPAA (Health Insurance Portability and Accountability Act of 1996) is United States legislation that provides data privacy and security provisions for safeguarding medical information.
- Due to HIPPA regulations, Carbon cannot receive files that have patient names in the file name or imprinted on the geometry.
If you need to send files to Carbon for technical support, remove the patient name from the file name and from the geometry.



- Select the Layout tab (Shift + L) in the top menu bar.
- Under Auto Layout, select Gen2.
- Gen2 usually gives the most effecient packing for dental devices.
- Enter at least 0.5 mm in Padding.
- Models require a minimum of 0.1 mm of space between them.
- Optimize starting rotation
- ON for models only or mixed builds
- OFF for dies only
- Leave Allowed rotations at the default setting.
- This gives the software maximum flexibility to fit the most possible parts on the build platform.
- Press the Auto Layout button to arrange your parts.

If necessary, nesting can be changed manually:
- Click and drag parts to adjust their position.
- Modify Z rotation by using the Spin tool or manual rotations under the Orient tab (Shift + O).
- Use the Part List tab as needed to more easily select models and focus on them.
Click Print Controls or Shift + P in the top menu bar.

Two print profiles for use with DPR 10 are available to all customers to provide Dental Labs with more control over print outcomes: DPR 10 Loosen Fit and DPR 10 Tighten Fit.
Reference Print Controls for more information.
For standard models, Carbon recommends a Slice Thickness of Standard (100 µ).
For crown and bridge, die fit, and analog implant models, Carbon recommends a Slice Thickness of Fine (50 µ).
- Select the Project Analysis tab.
- Click Start Analysis and wait for the processing to complete.
- Note the required resin volume and print time.
- Click Add to Queue.

Consult the protocol sheet for information about resin storage, dispensing, washing and curing.
If you have an AO Backpack, see Operation for information about using Automatic Mode for unattended printing.
To facilitate part cleaning, be sure to remove parts from the platform before washing.

Remove arches by putting the scraper under thick, strong features. The sides of this model are the thickest and strongest part with the smallest chance of breaking.
Apply less force at several locations rather than a large force at one location.

Be patient when removing models by putting the scraper blade under delicate features, as they can break during part removal.
Cleaning DPR 10 models with an orbital shaker requires two washes:
- First wash: 3 minutes in Container 1 with used IPA
- Second wash: 2 minutes in Container 2 with fresh IPA
"Used IPA" has cleaned one full platform of models.
Carbon recommends the following process for manual washing:
- First build of the day
- Fill both containers with fresh IPA.
- Perform both washes.
- Next build (see graphic below)
- Use Container 2 for first wash.
- Dispose of the used IPA from Container 1, refill with fresh IPA and use for second wash.
- Subsequent builds
- Continue the process from step 2 above.

Dispose of used IPA according to local regulations.
