I have and injection molding machine. I was thinking about making some standard parts for Delta 3D Printers. I wanted to get a sense of the level of interest and recommendations on which designs/parts people are interested in. https://reprap.org/forum/read.php?178,396322,396322#msg-396322 Wed, 16 Sep 2026 23:13:54 -0400 Phorum 5.2.23 https://reprap.org/forum/read.php?178,396322,401318#msg-401318 https://reprap.org/forum/read.php?178,396322,401318#msg-401318
I am currently casting an extruder for my Rostock. I can't stand using an FDM part for any mechanical purpose. Dogisht.

We've been looking into injection molding the Griffin Pro parts as a stretch goal and found that even the "simple" frame parts require multi-part molds, 4 for the lower, 6 for the upper. The Kossel Mini would probably require 6 parts for the upper and 6 for the lower, and based on the numbers we were given, you can expect several tens of thousands of dollars just for those unless you're an experienced mold maker.

Here's something else to consider,
I remember someone ramping up Rostock kits, and no sooner had they started production when the Kossel and Cerberus Pup came out and demand for Rostocks dropped nearly to zero. That's something you need to consider, you could spend a ton getting molds and a new delta could hit the next day leaving you stuck with no way to recover your costs.


@ Replace
See that cost estimate, a delta really only needs 6 or 7 unique (printed) parts, they get re-used over and over again. A cartesian has a pile of different parts and each part will require several thousand dollars each for a mold.]]> sheepdog43 Delta Machines Wed, 20 Aug 2014 04:54:15 -0400 https://reprap.org/forum/read.php?178,396322,396916#msg-396916 https://reprap.org/forum/read.php?178,396322,396916#msg-396916

I think that for lots of designs, a casing for the standard 8mm liniari bearing is interesting.
With a flat side and 2 holes bolting the bearing to any carriage.

If you want to sell stuff, you better aim at a specific design and mold all of the parts fir that one.
So you sell kits without vitamines.
