重要： These dimensions assume standard 2020 extrusion and Voron-spec frame construction. If using an LDO kit, the frame tolerances can vary by 0.5-1mm. Measure your frame's internal opening (width between left/right extrusions, height between top/bottom extrusions) and subtract 2mm total for clearance before cutting. It's better to cut 1mm oversize and sand down than to cut undersize and have a visible gap.
面板材料选择
亚克力 (PMMA)
亚克力是 Voron 构建中最常用的面板材料，主要因其价格更低且更易获取。透明亚克力透明度高，可清晰观察打印机内部。
- 成本： $15-30 per 3mm sheet (600x600mm). Significantly cheaper than polycarbonate.
- 透明度： Excellent optical clarity. Crystal clear when new.
- 耐刮擦性： Poor. Acrylic scratches easily — even wiping dust with a dry cloth can leave micro-scratches. Use a microfiber cloth and acrylic-safe cleaner (Novus plastic polish) only.
- 抗冲击性： Low. Acrylic is brittle. It can crack or shatter if impacted, especially at the edges where cutting creates micro-fractures. Not suitable for the door if the printer is in a high-traffic area.
- 耐热性： Softens at 80-100°C. In a Voron enclosure at 55-65°C, acrylic is fine. At higher chamber temperatures (70°C+), the panels may begin to bow or warp, especially the larger 350mm panels.
- 切割： Lasers cut acrylic beautifully. Score-and-snap works for thin sheets (3mm) but produces a frosted edge. CNC routing works but the edges need flame-polishing for clarity.
聚碳酸酯 (Lexan, Makrolon)
聚碳酸酯 (PC) 是 Voron 面板的优选材料。价格更高，但比亚克力耐用得多。
- 成本： $30-60 per 3mm sheet (600x600mm). Roughly double the price of acrylic.
- 透明度： Good, but not as optically clear as acrylic. Some polycarbonate has a slight yellow tint (UV-stabilized grades).
- 耐刮擦性： Moderate. Better than acrylic but still scratches. Many builders choose to leave the protective film on during installation and only peel it off once the build is complete.
- 抗冲击性： Excellent. Polycarbonate is practically unbreakable in 3mm+ thickness. It bends rather than cracks or shatters. If you bump the door with a filament spool, the panel will flex, not shatter.
- 耐热性： 120-130°C glass transition temperature. No risk of warping in any Voron enclosure, even with active chamber heating for high-temperature printing.
- 切割： Polycarbonate does NOT laser-cut well — it produces toxic chlorine gas (from chlorine-containing grades) and melts rather than vaporizes. Use CNC routing, score-and-snap, or a jigsaw with a fine-tooth blade. Laser cutting will produce burned, melted edges even on laser-safe PC.
面板厚度建议
- 3mm: Standard for side panels (left, right), top panel, and rear panel. Lightweight, easy to clip into place, sufficient rigidity for non-door panels.
- 4-5mm： Recommended for the front door panel. The door is the largest unsupported panel and the most frequently handled. A 3mm door flexes and looks flimsy when opening/closing. 4-5mm provides the rigidity needed for a satisfying door action and prevents sagging over time.
- 6mm: Overkill for Voron enclosures. The extra weight puts stress on the hinges and clips, and the visual benefit over 4-5mm is negligible. Only use if you want a bulletproof enclosure for a printer in a high-traffic environment.
切割方法
- 激光切割（仅限亚克力）： The cleanest method for acrylic. Laser-cut edges are polished, dimensionally accurate to ±0.1mm, and require no post-processing. Many online services (SendCutSend, Ponoko, local makerspaces) offer laser cutting. Cost: $5-15 per panel.
- CNC 雕刻机： Works for both acrylic and polycarbonate. Produces clean edges but they may need flame-polishing (acrylic) or sanding (polycarbonate) for a transparent edge finish. Dimensionally accurate to ±0.2mm.
- 划痕折断法（亚克力）： For thin acrylic (3mm). Score a line with a scoring knife, snap along the line. The result is a frosted, rough edge that needs sanding with 400-800 grit sandpaper and flame-polishing for clarity. Risk of micro-cracks at the corner if not scored properly.
- 细齿曲线锯： Works for both materials but produces a messy edge. Use a blade with 10+ teeth per inch. Clamp the sheet firmly and cut slowly. Sand the edges with progressively finer grit (120 → 240 → 400 → 800) for a clean finish. A router with a flush-trim bit can clean up jigsaw-cut edges.
对大多数构建者，我们建议从服务商订购激光切割亚克力面板。所有 5 块面板（3mm 侧板 + 4mm 门板 + 3mm 顶板/背板）的总成本通常为 $50-80（含运费）。与 DIY 切割相比，其精度和成品质量值得投入。
门选项 — 铰链式 vs 滑动式
铰链门（最常见）
标准 Voron 门使用3D打印铰链安装在前部型材上。门从侧面打开。选项：
- 3D 打印铰链： The Voron spec includes printable hinge models (left-hinge.stl and right-hinge.stl). These use M3 screws and a printed hinge pin. They work well but printed hinges wear over time. Print in ABS or PC, not PLA (which will soften in the enclosure).
- 钢琴铰链（连续铰链）： A 400-500mm aluminum or stainless steel piano hinge spanning the full height of the door. Much more durable than printed hinges. Mounts between the door and the front extrusion. Cost: $8-15 on AliExpress. Use M4 screws to attach.
- 磁吸铰链： Rare but clean. The door is held on with strong neodymium magnets embedded in the door and frame. The door lifts off completely for full access. Requires precise magnet alignment and 10x 8x3mm N52 magnets per side. Not recommended for heavy 5mm doors.
滑动门（替代方案）
一些建造者偏好可左右滑动或向上开启的推拉门。推拉门使用安装在上部型材上的T型导轨或线性导轨，门体连接滚轮或轴承滑块。推拉门无需打印机前方预留空间，但机械结构更复杂，且需妥善密封。
面板夹与安装
面板通过卡入2020型材T型槽的夹扣固定。Voron 规格使用打印的压入式夹扣。
- 标准压合夹扣： The Voron project provides STL files for panel clips. These press into the extrusion slots and the panel slides into place behind them. Each panel needs 4-6 clips (2 on each side minimum). Print in ABS. Cost: negligible (filament only).
- 快拆蝶形螺丝夹扣： A popular mod. Uses M3 thumb screws instead of press-fit. Allows tool-less panel removal. Print the clip body and use M3x8 thumb screws (AliExpress, $5 for 50). Much more convenient for accessing the printer interior.
- 磁吸夹扣： Use 6x3mm neodymium magnets embedded in printed clips. The panel is held by magnetic force. Quick to remove but weaker than screw-based clips. Sufficient for top and side panels but not recommended for the door.
面板密封 — 保持机箱气密性
打印 ABS 时，气密外壳至关重要。泄漏会导致热量散失，增加维持稳定腔室温度的难度。密封所有面板与框架接触的边缘。
- 闭孔泡沫胶带： 3mm thick, 6-10mm wide. Apply to the inside edge of each aluminum extrusion before installing the panel. Closed-cell foam doesn't absorb moisture and maintains its seal over years of enclosure heat cycles. Cost: $5-10 per roll (10m).
- 硅胶密封条： Apply a bead of high-temperature silicone (rated to 200°C+) along the extrusion channel before fitting the panel. Cleaner than foam tape but permanent — you can't remove the panel without breaking the silicone seal. Best for the rear panel which you rarely need to remove.
- 挡风雨条： EPDM rubber weather stripping (D-profile) from a hardware store. Cheaper than foam tape but may outgas at enclosure temperatures for the first few heat cycles. Let it bake at 60°C for 24 hours before putting any printed parts inside.
门密封最为关键。添加磁吸扣或门闩，使门紧密压合泡沫密封条。未完全密封的门会使外壳热效率降低50%。
面板组装顺序
- 粘贴密封胶带 to all extrusion faces that contact panels. Do this before installing any panels.
- 先安装后/背板。 It sits behind the Y-axis cable chain and is the least accessible once the printer is fully assembled. Slide it into place and secure with clips.
- 安装左右侧板。 These attach to the sides. If your left panel has an electronics bay cutout, ensure the panel orientation is correct (cutout at the bottom). Secure with clips.
- 安装门板。 Attach hinges to the left or right side (whichever you prefer for opening). Mount the door to the front extrusion. Adjust hinge tension so the door stays open at 90 degrees without slamming closed. Add the door handle.
- 最后安装顶板。 It sits above the gantry and is easiest to install last. If you have a Nevermore filter, install the filter mount in the top panel before attaching the panel to the frame.
最终紧固前测试所有面板贴合度。若面板略大，用锉刀或砂纸打磨边缘——切勿强行卡入夹扣，以免导致面板边缘开裂。若面板略小，可额外添加一层泡沫胶带填补间隙。
Nevermore 过滤器安装位置
Nevermore 碳过滤器通常安装于顶部面板或后面板。Nevermore V5 和 V6 设计有特定开孔模式：
- 顶部安装： The Nevermore sits on top of the printer, recirculating air through the top panel. Cut a 120mm x 120mm hole (for 120mm fan Nevermore) or 140mm x 140mm (for 140mm fan). The filter pulls air from inside the enclosure and exhausts back through the top panel. This is the most common placement.
- 后部安装： Mount the Nevermore on the inside of the rear panel. The filter recirculates air within the enclosure. No external exhaust hole needed — the filter inlet and outlet are both inside the chamber. This placement is cleaner but slightly less effective than top-mount because the rear panel location is not at the highest point of the enclosure (hot air rises).
- 侧面安装： Some builders mount the Nevermore on the left or right panel near the bottom, pulling cool air and pushing it through the carbon bed. Not recommended — the carbon filter works best at the top of the enclosure where the air is hottest (most volatile fumes present).
门把手选项
- 3D-printed handle: Many STL files available on the Voron user mods repository. Print in ABS or PC. Simple bar or hook design. Cost: negligible (filament only).
- Aluminum bar handle: A 100-150mm aluminum extrusion bar, 15-20mm wide, mounted with M4 screws through the door. Much more durable than printed handles. Cost: $5-10 on AliExpress.
- Plastic cabinet handle: A standard kitchen cabinet handle from a hardware store. Usually stainless steel or zinc alloy. Cost: $3-8. Choose a handle with enough clearance for your fingers to grip comfortably.
