3D打印如何工作

数字模型被切片成层。每一层经固化、烧结或挤出后，再叠加下一层，直到零件完成。

  1. 读取文件

    上传STEP、STL或3MF。系统读取壁厚、体积与支撑风险。

  2. 匹配工艺

    在同一报价里对比工艺与材料——树脂、尼龙或金属。

  3. 设定后处理与数量

    下单前选择后处理（打磨、染色、气相抛光、机加）与数量。

  4. 打印发货

    我们打印、检测并发货，交期写在报价行上。

什么是3D打印

3D打印（增材制造）根据CAD或网格文件，把光敏树脂、热塑性塑料或金属粉末一层层堆成实体。材料只加在模型需要的位置，因此点阵、内部流道和单件异形不必单独开模。

在AIHFABS，同一份上传可以给树脂、尼龙和金属工艺报价。按外观、强度或耐热选工艺，再在报价里加染色、气相抛光或机加，不必另发一轮询价。

主要3D打印工艺

多数需求落在FDM、SLS、SLA、MJF。金属SLM、DLP、LCD在下方能力列表中。

这项3D打印服务擅长什么，以及边界在哪

先看优势栏判断增材是否该作为第一条路径；再看限制栏，知道何时该交给CNC或注塑。

优势

  • 少夹具的复杂结构 内部流道、点阵、一体化装配，CNC往往需要多次装夹。
  • 当周可出的原型 文件确认后，多数塑料件数小时到数天即可出厂。
  • 按需打印 模型留在库里，改版后再打，没有过期库存。
  • 按用途选材料 树脂做出细节，尼龙做卡扣和风道，TPU做弹性件，承热承力再上金属。
  • 从文件到零件一步完成 1–200件不必软模。改设计改CAD即可。
  • 减材废料更少 材料进入零件和支撑，而不是整块坯料。粉末床可回收未烧结粉。

限制

  • 不是所有材料都能打 主要是树脂、部分尼龙、TPU和有限金属。食品接触和部分合金要换工艺。
  • 成形尺寸 超过腔体的零件要拆件再粘接，增加时间和接缝。
  • 通常需要后处理 支撑、粉末和层纹要清理，外观面或密封面才能用。
  • 单价下降不明显 不像注塑，打到几千件时单价也不会大幅下降。
  • 分层结构 FDM各向异性更明显。受力路径应顺着层，或改SLS、MJF、CNC。
  • 公差因工艺而异 塑料件常见约±0.2–0.3 mm。关键孔仍建议打印后再机加。

3D打印常见问题

应该选哪种3D打印工艺？

按用途选：SLA/DLP/LCD适合光滑外观件；SLS/MJF适合耐用尼龙件；FDM适合低成本治具；SLM适合金属。各子页列出材料与限制。

在线3D打印精度如何？

塑料件一般约±0.2–0.3 mm；金属SLM机加后更紧。精确能力见各工艺页，并以报价确认为准。

可以3D打印和CNC混用吗？

可以。很多订单先打印近净形，再机加关键面。从本页开始，需要减材时再进入SLM或CNC落地页。

需要什么文件？

金属和后续机加优先STEP；塑料件STL或3MF即可。一次上传可为所选工艺报价。

Engineering guide to custom 3D printed parts

Industrial 3D printing builds a part layer by layer, but the choice of resin, powder or filament changes its mechanical behavior, surface and post-processing route. Select for the application rather than the technology name. Use the process comparison below to narrow the route, then review the linked process guide for the part geometry.

Process selection: application, material and design constraints
Process and materialsUseful applicationsEngineering tradeoff
SLA / DLP / LCD · photopolymer resinsDetailed visual models, masters and fit-check partsSupport contact and post-curing affect the finished part. Check heat, UV exposure and long-term load requirements for the selected resin.
SLS · nylon and supported flexible gradesClips, ducts, housings and functional prototypesPowder supports the build, but cavities still need cleaning access. Surface texture and thin features affect sealing and assembly.
MJF · supported nylon gradesFunctional polymer parts and repeated small batchesPacking and orientation influence build planning. Confirm grade, color, finish and critical interfaces rather than assuming all nylon parts behave alike.
FDM · thermoplastic filamentConcept models, fixtures and larger practical prototypesLayer direction and toolpath affect strength. Support-facing surfaces may differ from the top and side walls.
SLM · metal powder alloysComplex metal brackets, passages and consolidated assembliesResidual stress, support removal and finishing need planning. Precision bores or sealing faces may need secondary machining.

Design for orientation, supports and cleaning

Show the load direction, cosmetic face and mating interfaces before the build orientation is finalized. Avoid trapped powder or resin inside closed cavities. Provide accessible drains and cleaning paths for hollow parts, allow for support removal and identify thin features that need special review. A minimum wall value is meaningful only with its material, unsupported span and orientation.

Choose materials by service conditions

Check stiffness, impact behavior, sustained temperature, moisture exposure and the environment in which the part will be used. PA12, PA11, TPU, engineering resins and metal alloys solve different problems. Use the exact grade datasheet; a familiar trade name or an ABS-like label is not proof of equivalence to another manufacturing material.

Separate build accuracy from assembly fit

Whole-part dimensional accuracy, local feature resolution and a working clearance are different specifications. Holes, mating pins and thin walls can respond differently to orientation and finishing. Mark critical dimensions on a drawing and state the mating component or required fit. Confirm the accepted tolerance and measurement condition in the quote.

Plan post-processing before printing

Cleaning, curing or depowdering is part of the manufacturing route. Dyeing, painting, polishing, smoothing and metal machining add different effects to appearance and dimensions. Specify color, texture, visible surfaces, masking and fit-critical features. Coatings and smoothing can change a clearance; metal finishing may require machining stock.

Inspection and production release

Agree the material grade, file revision, orientation-sensitive requirements and finished-part dimensions before production. For a first run, use a sample to evaluate fit, surface and handling. Ask which dimensional or material documentation can be supplied for the order. Safety-critical or regulated applications require their own application validation and agreed acceptance plan.
