Perakitan & Arsip Data

1. Persiapan Model

Sumber Model 3D:

Hasil scan
Website model 3D
Vendor / 3D modeller

Blender — Cleaning & Sizing

Import model 3D
Bersihkan:
- Non-manifold geometry
- Lubang besar
- Objek hasil scan yang tidak diperlukan
Set ukuran model ke ukuran akhir produk
Pastikan model solid (tidak hollow)
Export .obj

2. Retopologi & Validasi Mesh

Instant Meshes — Retopology

Import file hasil cleaning
Set Target Vertex Count sesuai kebutuhan finishing
- Semakin tinggi → detail naik, beban proses naik
Klik Solve (Orientation & Position Field)
Export .obj

Blender — Mesh Validation

Import file hasil retopologi
Cek:
- Siluet halus
- Kepadatan mesh merata (tidak terlalu padat di area datar)
Jika hasil buruk → ulangi tahap Retopologi

Base Preparation

Extrude sisi bawah model
Potong bagian bawah menggunakan Boolean
Export .obj

3. Shelling

Autodesk Meshmixer — Hollow

Import file hasil validasi mesh
Edit → Hollow
Offset Distance: 4 mm
Jika muncul lubang:
- Atur Solid Accuracy & Mesh Density
- Kecilkan Hole Radius bila perlu
Export .obj
- Nama file: NamaProyek_Model3D

4. Pemotongan Model

Blender — High Priority Cut

Import file hasil shelling
Identifikasi High Priority Surface
- Contoh: wajah patung, ornamen utama
Potong bagian high priority (Boolean)
Export:
- NamaProyek_HIGH_PRIORITY.stl
- NamaProyek_LUBAN.stl (badan utama)

5. Slicing & Printing

LuBAN — Modular Cut

Import file LUBAN
Mesh → Cut

Pengaturan Utama:

Method: Modular Cut
Unit: mm
Pastikan ukuran model sesuai ukuran akhir

3D Printer:

Bed Shape: Rectangle
Printer Size: 230 × 230 × 230 mm
Close Cut: ON
Axial Cut: ON
Part Number: Yes
- Start Number: 1
- Prefix: 2 huruf inisial model

Connector:

Type: Plug
Shape: Square (Number = 8)
Tolerance: 0.2 mm
Final Shape: Native
Klik Cut
Simpan ke folder: NamaProyek_MAIN_BODY_CUT
Hapus komponen berlabel tiny

6. Printing

Bambu Studio

Prepare → Add file:
- MAIN_BODY_CUT
- HIGH_PRIORITY
Load as single object with multiple parts: NO
Auto Arrange:
- Spacing: 2 mm
- Auto Rotate: ON
Allow multiple materials on same plate

Penataan Plate:

Sisi sambungan tidak kena support
Gunakan Lay on Face
Minimalkan overhang
Maksimalkan jumlah komponen per plate
Simpan project: NamaProyek_PLATE

Support & Slice:

Enable Support: ON
Type: Tree (Auto)
Slice All → Generate G-code
Print / Send ke printer Bambu Lab

7. Arsip Data

Simpan semua file:
- Model sumber
- File kerja (.obj, .stl)
- Project Bambu Studio
Upload ke Google Drive sesuai struktur proyek
