How to make clear aligner
It explains how to make devices using 3D printers.
Select printer
DLP/SLA or FDM type printer can be selected according to user environment or purpose.
* Minimum specification: 100㎛ or less for X/Y/Z-axis resolution
DLP/SLA type
FDM type
Type of curing resin with light
Type of laminating by melting filaments
Strength
1. Popular
2. Cheap equipment and materials
3. Long product life
4. Strong print strength
5. Convenient post-processing
Weakness
1. Slow printing
2. The printout surface is rough and not precise
Strength
1. Fast printing
2. The printout surface is smooth
3. It can manufacture much smaller and more precise prints than FDM type
Weakness
1. It is difficult to make large prints due to brightness or distortion by wide light
2. Weak print strength
3. Short product life
4. Sensitive to temperature. Deformation occurs at room temperature over 60℃
5. Expensive equipment and materials
Sophisticated output: SLA > DLP
Printing speed: SLA < DLP
Maintenance: SLA < DLP
Preparation
Slicing program settings and
check points by equipment
By adjusting the Z-axis of slicing program,
lightly bury the model or us a floor aid to
prevent print failure.
Check points to avoid printing failure
Check floor temperature
Check for foreign objects
The resin should be well mixed
Check floor temperature
Check filament twisting
Check for nozzle clogging
DLP/SLA type
FDM type
Printing
DLP/SLA type
FDM type
Post-processing
This is a job only for DLP/SLA printers,
there is a process of removing excess resin remaining on the printout and curing.
Put the printout in a barrel filled with alcohol, remove excess resin with a fine-bristle toothbrush.
Put the dried printouts into the curing equipment.
