<p data-sourcepos="1:1-1:82" >Here are the common types of 3D printers you might find in a community makerspace:</p>
== Fused Deposition Modeling (FDM) Printer ==
<p>This is the most common type of 3D printer for hobbyists and makerspaces due to its affordability, ease of use, and wide variety of materials. FDM printers work by extruding a thin filament of thermoplastic material through a heated nozzle, building the object layer by layer.</p>

== '''Stereolithography (SLA) Printer''' ==
&nbsp;SLA printers use a vat of liquid resin and a laser to cure the resin layer by layer, creating a very high-resolution print. However, SLA printers can be more expensive than FDM printers and the resin can be messy and hazardous to handle.
**<p data-sourcepos="19:3-19:17">'''Advantages:'''</p>
****High resolution and smooth surface finish
****Good for creating detailed models and prototypes
**<p data-sourcepos="23:3-23:20">'''Disadvantages:'''</p>
****More expensive than FDM printers
****Limited material selection (mostly resins)
****Resin can be messy and hazardous to handle
****Requires post-processing (cleaning and curing)
**'''Common Materials:'''
****Standard Resins: Offer a good balance of properties for general-purpose printing.
****Tough Resins: Simulate ABS-like strength and durability.
****Flexible Resins: Mimic rubber-like qualities for functional parts requiring flexibility.
****Castable Resins: Designed for burning out the printed mold to create metal castings.
****Biocompatible Resins: Used for medical and dental applications requiring biocompatibility.

== '''Selective Laser Sintering (SLS) Printer''' ==
SLS printers use a laser to sinter together tiny particles of powder, such as nylon or metal. SLS printers can create very strong and functional parts, but they are the most expensive type of 3D printer on this list.
*<p data-sourcepos="31:3-31:17">'''Advantages:'''</p>
***Creates strong and functional parts
***Wide variety of materials (including nylon and metal)
***No need for support structures for most designs
*<p data-sourcepos="36:3-36:20">'''Disadvantages:'''</p>
***Most expensive type on this list
***Requires specialized ventilation due to fine powder particles
***SLS printed parts may have a slightly rough surface finish
*'''Common Materials:'''
***Nylon: The most common SLS material, offering good strength, flexibility, and heat resistance.
***Polypropylene (PP): Lightweight and chemically resistant, suitable for living hinges and functional parts.
***High Temperature Nylon (HT Nylon): Enhanced heat resistance for parts exposed to higher temperatures.
***Glass-filled Nylon: Nylon infused with glass particles for increased strength and stiffness.
***Selective Laser Melting (SLM) can also be included in this category, using metals like aluminum, stainless steel, and titanium for high-strength parts.

== '''PolyJet Printers''' ==
These printers work similarly to inkjet printers, but instead of ink, they jet droplets of a photopolymer resin that cures under UV light. Similar advantages to SLA (high resolution) but more expensive and complex.

'''Common Materials:'''
*Photopolymer Resins: Similar to SLA resins but come in a wider variety, including rigid, flexible, and biocompatible options.

== '''Digital Light Processing (DLP) Printers''' ==
DLP printers use a projector to cure a vat of liquid resin layer by layer, similar to SLA printers. Similar to SLA but potentially faster cure times due to projector light source.

'''Common Materials:'''
*Similar to SLA resins, offering a variety of options depending on the specific printer model.

== '''Binder Jetting Printers''' ==
These printers use a inkjet head to jet a binding agent onto a bed of powder, building the object layer by layer. More limited material options compared to FDM, but can be good for full-color printing.

'''Common Materials:'''
*Powdered Materials: Can include gypsum for creating detailed models, sandstone for a stone-like finish, and even full-color options using multi-material printing techniques.

== '''In summary:''' ==

**Choose FDM for affordability, ease of use, and a wide range of materials for initial forays into 3D printing.
**SLA is ideal for high-resolution prototypes and detailed models.
**SLS is suited for creating strong and functional parts when strength is a priority.
**Consider the other options for specific needs like full-color printing or faster cure times, but be aware of their potential drawbacks.
