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.
10. Legal Compliance¶
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.
Design rule testing¶
Download app¶
Creality app¶
UltiMaker Cura¶
Check for models free online¶
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.
