3D Scanning and Printing

Group assignment requirements

The group assignment for this week is the following:
- Test the design rules for your 3D printer(s)
- Document your work on the group work page and reflect on your individual page what you learned about characteristics of your printer(s)

Safety Guidelines for Using the 3D Printer

1. Follow Instructions Carefully

Always operate the printer according to the instructions provided in the user manual. This ensures safety and prevents injury or damage to the equipment.

2. Proper Placement

Ensure the printer is not placed near heat sources, flammable materials, or explosive substances. It’s best to place it in a well-ventilated, cool, and dust-free environment to maintain optimal performance.

3. Stable Environment

Position the printer on a stable surface, away from strong vibrations or unstable conditions. These factors can negatively impact print quality. Always use the recommended filaments to avoid clogs or damage to the extruder.

4. Use the Correct Power Cable

Do not use power cables from other devices. Always connect the printer to a grounded three-prong outlet using the cable provided with the printer.

5. Avoid Contact with Hot Surfaces

Never touch the nozzle or heated bed while the printer is operating. These components can reach high temperatures and may cause burns or injury.

6. Appropriate Clothing

Do not wear gloves, loose clothing, or wraps when using the printer to prevent the risk of entanglement in moving parts, which could lead to crushing or cutting injuries.

7. Safe Cleaning

Use the provided tools to remove filament from the extruder, taking advantage of the residual heat after printing. Avoid touching the extruder directly during cleaning to prevent burns.

8. Regular Maintenance

Perform regular cleaning by wiping down the printer with a dry cloth after powering it off. Remove any dust, leftover filament, or foreign debris from the guide rails to keep the printer in good working condition.

9. Supervision for Children

Children under the age of 10 should not use the printer without adult supervision to ensure safety and prevent potential injury.

Users must comply with the laws and regulations of their respective countries or regions where the printer is used. The printer must not be used for illegal activities. Creality is not responsible for any legal consequences resulting from misuse of the equipment.

Slicing

The design was sliced using [name] slicer software. [brief about the software used]

The settings used were the following:

Material: [PLA or other material used]
Rafts: Yes
Support: No
Resolution: [layer height. use 0.1 or finer]
Infill: [30% or whatever the test calls for]

The estimated time to finish printing was [time estimate from the slicer software], estimated amount of material needed was [material amount in meter or grams]

Printing process

Tutorial

Ultimaker

Import

Scale

Support + ‘slice’

Result

The support is too difficult to remove there is no enough spacing you could damage the design piece.

Adjustment

In ultimaker cura it is crucial to adjust the support overhang angle to 70 degrees

Transport to 3d-printer

Using SD card

Creality Print

In creality the support auto is good you if you want you can adjust the support overhang angle.

Step 1: Import file (.stl)

Step 2: Scale

Step 3: Support

Step 4: 3d-printer set-up

There is no issues the support was easily removed after print

Overhang

In the Forbiden fruit design there is an overheng were there is a gab in the sides that need to be supported by tree branch. Fixing the angle between 60-75 was best for printing were we can see important tree branch support needed not extra or few.

Bridge Test

3d-printer test should be with no support at all. Bridge test it is a way to see when the filament start to crash as the elevation of the nozzle increases and the width (distance travels) increases. As shown in the picture there fixed increase increment in each step the filament behave aggressive toward the gravity as it progress the filament become fragile and hair-liked structure

Fine details and accuracy

Comparision

The Creality 3d-printer create detailed print and easier tree support to remove tree support with minimum damage to the designed piece.

(Black (Ultimaker))- Forbiden Fruit) The lines are much brittle using ultimaker, were ther few hair like strand of material all over the printed peice. The adhesion of the PLA material to the designed object were high were the tree branches support were hard to remove and damage the detail of the printed peice.

(Yellow and Blue) On the other hand, The Creality 3d-printer create detailed print and easier tree support to remove tree support with minimum damage to the designed piece.

Result

Ultimaker - Black boat

There were some difficulty transporting the design to the machine were some laptops cannot read the SD card. The time of the Print is too much some us waited more than 12 hours and the final result was less than expected or even a failed attempt The tree branch were adhesive an damaged the printed design.

Creality- Yellow and Blue boat

both been printed with same material,condition and material specification, however for some unknown reason the yellow filement gave us better and clearer result specially regarding the curves and final finish.
