Industrial plants need exact ways to make real parts. You choose between old ink systems and new additive manufacturing. Old ways put ink on surfaces with plates or screens. Additive systems stack raw materials layer by layer. They build solid 3D things.
Core Selection Parameters: Engineers pick the best way by checking dimensional accuracy, surface roughness, throughput, and isotropic material properties.
Dimensional accuracy checks exact part sizes. Surface roughness shows texture quality. Throughput tracks full production speed. Isotropic material properties give equal strength everywhere. You judge Printing Technologies well by checking these key measures against your part costs and strength needs.

Old factory methods split picture parts and blank parts. They use different surface shapes to do this. You can find four main shapes here. They are flat, raised, sunken, or holey surfaces. These old ways make matching copies very fast. Big factory runs cut your single item costs. They cost much less than 3D printing.
Offset lithography uses a flat top shape. Plant experts name this idea planography. Oil and water push away from each other. You use this trick instead of high walls. You treat metal plates with safe chemicals. This step makes picture spots hold oil ink. Blank spots hold water and push ink away. You roll ink onto a soft cylinder first. Next, the soft cylinder rolls ink on paper.
You put paper into machines as single sheets. You can also use long paper rolls. Sheet machines print flat paper, card boxes, and boards. Web machines print paper rolls at super fast speeds.
Press Category | Operational Benchmark | Maximum Speed Rate |
|---|---|---|
Sheetfed Offset | Standard production range | |
Flagship Sheetfed | Advanced commercial standard | |
Web Offset | Linear continuous web speed | 3,000 feet per minute |
Web Offset | Cut-off production rate | Up to 80,000 cut-offs per hour |
Flexography uses raised top shapes on parts. You stick bendy rubber plates onto spinning tubes. A hard ceramic roller moves set ink amounts. It sends ink to the high plate spots. Teeny holes cover the hard roller surface. These small holes hold exact ink amounts. The plate takes ink from the roller. Then it stamps ink right on your stuff.
ℹ️ Fast-Drying Ink Transfer: Flexography uses thin, fast-drying inks. You print stacked color coats with no mess.
Flexo tools print on nearly any item. Bendy plates fit rough items with ease. You can print on box boards and plastics. You can also print on foils and stickers. Fast flexo printing leads the huge box market.
Gravure printing uses sunken top shapes. You cut millions of teeny holes into steel. These heavy steel tubes have thin metal coats. A flat doctor blade scrapes extra ink away. Ink stays inside the tiny cut holes only. Your paper goes between two heavy spinning tubes. A soft tube presses paper deep into holes. This action pulls out all the wet ink.
Gravure tubes give great strong life. Metal coats shield the tiny holes from wear. This shield lasts over millions of non-stop prints. You make bright pictures with deep ink coats. You also get rich full color mixes. Big book shops and box makers pick gravure. These traditional printing technologies run well for long times.
Screen systems use open shapes. You pull fine mesh tight. A metal frame holds it. Strong plastic or steel wire works. Soft light-sensitive liquid coats it. Light blocks the plain spots. Water washes the open holes clean.
You put substrate right under it. Next, pour thick ink on top. A rubber blade presses down hard.
Squeegee Dynamics: You balance blade pressure and speed. Good control keeps edges sharp.
The blade pushes ink through holes. The mesh touches paper fast. Then, it snaps back up quickly. This step leaves crisp ink marks.
Screen systems print super thick ink. You print on thin glass plates. Ceramic, plastic, and cloth work too.
Factories build electronic parts now. You print silver circuits easily. Carbon lines and insulator coats work. Solar makers print silver lines fast.

Extrusion Tip: Keep nozzle heat steady. Bad heat makes weak layer bonds.
You push wet ink through small nozzles. Air pumps supply steady force. You lay fluid inks with zero heat. Air or UV light hardens paste lines. Engineers print hydrogels and clay pastes this way.
You fill a tub with liquid resin. UV light turns liquid resin hard fast. A UV laser traces your 3D design. Mirrors point the laser spot on liquid. The plate drops down after each layer.
Digital Light Processing uses a screen projector. You flash a whole 2D layer image.
SLA Resolution Scalability: System build size stays separate from print clear quality.
DLP Trade-Off: Quality depends on projector pixels. Closer screens shrink the build space.
Feature | Stereolithography (SLA) | Digital Light Processing (DLP) |
|---|---|---|
Curing Mechanism | Traces paths point-by-point using a UV laser beam | Flashes an entire 2D layer image simultaneously via a projector |
Feature Resolution | High fine XY resolution (<100 μm) with ultra-smooth interpolated curves; build volume is independent of resolution | Pixel-based resolution defined by voxel sizes; direct trade-off between print resolution and build volume |
Curing Speed | Generally slower because the laser must trace each feature individually | Faster print speeds for many parts due to single-flash full-layer curing |
You spread thin polymer powder in a box. A laser heats powder spots to melt them. You do not need extra solid supports. Loose powder holds up hanging parts easily.
Polymer powder systems mix 30 percent new powder with old powder for builds.
Adding 30 percent new powder stops material heat damage over time.
Multi Jet Fusion uses ink arrays and lamps. You spread plastic powder on hot beds. Ink sprays on exact part spots. Outer edge agents keep lines clean. Strong heat sweeps over the powder bed. Hot spots melt while plain powder stays cool.

Process Step | Operational Action |
|---|---|
1. Powder Layering | A counter-rotating roller spreads fine powder smoothly over the build plate. |
2. Selective Jetting | Inkjet nozzles drop liquid adhesive onto targeted powder areas. |
3. Curing Pass | An overhead heater dries the liquid glue to bind the current layer. |
4. Z-Axis Drop | The build platform drops down, ready for the next fresh layer of powder. |
You never melt powder during builds. Binder glues powder particles at room heat. Cold steps stop thermal heat stress. This stops heat warp defects too. Loose powder holds up hanging parts. You need no extra support structures.
You remove glued parts from powder. Experts call this a green part. Green parts stay weak and fragile. You bake metal parts in furnaces. Heat burns glue and fuses metal. This step makes strong metal parts.
Factories turn digital models into real plastic parts. You pick specific methods to meet your strength goals. Plastic builds use three main setups. These are nozzles, resin tubs, and powder beds. Heat or light changes these plastic items fast.
Fused Deposition Modeling melts long plastic wire. You push hard plastic into a hot tip. A drive gear pushes the wire inside. The plastic melts into soft goo quickly. The hot nozzle drops soft goo down flat. The nozzle moves along set computer paths. Soft plastic cools down and bonds fast. You stack thin layers to build solid items.
You use strong factory plastics in FDM tools. Plain PLA works well for quick tests. Hard jobs need tough plastic materials:
Acrylonitrile Butadiene Styrene (ABS): Pick ABS for tough, high-impact parts.
Polycarbonate (PC): Pick PC for super strong, heat-proof parts.
Polyether Ether Ketone (PEEK): Use PEEK for tough jobs with strong chemicals.

These materials give real factory part strength.
FDM parts show different strength across directions. Your printed item stays weaker between layers. The layer bonds stay weaker than plastic strands. Pulling layers up along the Z-axis causes breaks.
You change part strength by setting key printer values:
Nozzle Temperature: Higher heat makes layers stick much better.
Feed Rate: High speeds weaken bonds and cut strength.
Layer Thickness: Thickness shapes part strength and look.
Raster Angle: Angle sets print strength direction paths.
