 ===ABS===
 ABS is a strong and reasonably impact-resistant material at a moderate price, but warps easily and smells worse while printing. Its low density makes it one of the lightest of all printable plastics (PLA is about 20% heavier for the exact same print). You'll probably need to print it in an enclosure for best results; this keeps its temperature even during printing, so that it only shrinks after printing instead of curling or warping during printing. Many hobbyists ventilate the enclosure to the outdoors with fan(s) due to the odor.
 ===TPU and flexibles===
-"TPU" is a name given to the wide range of semi-flexible filaments available for 3d printers. These are gaining popularity in combat robots because they can be used for "shock mounting" components in larger weight classes, or as armour in smaller weight classes. The advantage is that the material bends under forces, then springs back into shape, avoiding serious damage. TPU can be printed with medium difficulty on most 3d printers. The disadvantage is that it might not be sufficiently rigid for structural elements.

+Polycarbonate is super strong - your robot arena walls are probably made from it! Many printers can't print it, though, because it must be heated to an extreme temperature (about 275°C/525°F). However, you can buy clear sheet polycarbonate at hardware stores and plastic supply houses, and shape to suit your needs. You've probably seen robot kits with clear plastic covers; those are "polycarb" and they make for good armor against moderate attack strength.

 ==Budget==
 Desktop and office 3D Printers can range from as low as $150 to over $10,000 depending on their hardware, capabilities, build volume, and other factors. Here's a quick overview of what's available:
-*'''Budget-friendly/hobbyist 3D printers:''' Range from $150 - $750, normally limited in materials and build volume.  These include machines like the Creality Ender 3 series, and will normally have a maximum nozzle temperature of 245-250° Celsius.  These machines are meant for printing PLA, PETG, and ABS, but with varying degrees of modification can print more advanced materials like Nylon and TPU.
+*'''Budget-friendly/hobbyist 3D printers:''' Range from $150 - $750, normally limited in materials and build volume.  These include machines like the Creality Ender 3 series, and will normally have a maximum nozzle temperature of 245-250° Celsius.  These machines are meant for printing PLA, PETG, and ABS, but by replacing or modifying some components, they can print more advanced materials like Nylon and TPU.
-*'''Advanced materials printers:''' Range from $750 - $3,000, and are capable of printing materials like PLA, ABS, PETG, TPU, Nylon, Nylon Composites, and Polycarbonate blends with minimal or no aftermarket modifications. These will have a maximum nozzle temperature around 295-300° Celsius.
+:Note: Some low-end crafting printers don't have a heated printing surface. These should be avoided, since they don't work with a variety of plastics.
-*'''Engineering grade printers:''' Range from $3,000 - $10,000+, with few materials outside of their capabilities. These printers are often able to print not only advanced materials but also multiple materials using multiple extruders or multiple tool heads, allowing for even greater complexity. Dual extrusion can allow for a multi-color part (Black PLA/White PLA), multi-material finished product (PLA/PETG), or soluble support material like PVA/BCOH.
+*'''Advanced materials printers:''' Range from $750 - $3,000, and are capable of printing materials like PLA, ABS, PETG, TPU and other flexible types, Nylon and nylon composites, and Polycarbonate blends with minimal or no aftermarket modifications. These will have a maximum nozzle temperature around 295-300° Celsius and can heat their print surface to 100° Celsius or more.
